The University of Bristol is part of a project to to put a quantum satellite into orbit.
The RefQ project is led by Craft Prospect in Glasgow with the University of Strathclyde to test out quantum key distribution (QKD).
The group is developing a space-based photonics source of quantum signals for launch on the Canadian QYESSat (Quantum Encryption and Science Satellite) mission.
Bristol researchers are working on the quantum source to be integrated into the satellite and the testing of new ways to distribute quantum encryption keys from space. Strathclyde will also collaborate with the project’s academic lead, the University of Waterloo in Ontario, on theory and modelling of the quantum payload, as well as developing secure communication protocols based on the new hardware.
The first prototypes of the UK systems have been delivered and are now undergoing integration testing in Canada.
“The quantum key distribution technology developed in this project represents a major step towards realising space-to-ground secure key distribution, a truly transformative technology,” said Prof John Rarity from the University of Bristol’s Quantum Information Institute.
“The source we develop with our project partners, Craft Prospect and the University of Strathclyde, will fly on board the QEYSSat Satellite extending the scope of the mission to demonstrate links to ground stations on both sides of the Atlantic.”
“This project aligns with the efforts to build collaborations between Strathclyde and the University of Waterloo in the area of quantum technologies. Craft Prospect is also a long-term commercial partner with Strathclyde in the development of CubeSat quantum key distribution,” said Daniel Oi, Senior Lecturer in Strathclyde’s Department of Physics, is the University’s lead on RefQ.
“In addition, RefQ is connected with the UK Quantum Technology Hub in Quantum Communications, in which Strathclyde is a partner, in its mission to launch a CubeSat in 2023-24.”
The quantum key distribution technology developed in this project is targeted to fly on board QEYSSat, demonstrating links to ground stations on
“We are only at the start of developing quantum technologies, but it is already clear that they offer us a world of opportunity across entire sectors like healthcare, communications and financial services,” said UK Science Minister Amanda Solloway.
“The UK and Canada have a strong collaborative relationship in science and technology. By our businesses and academics working together, these incredible new projects will help us accelerate the development, scale up and commercialisation of quantum technologies, ensuring the UK remains a world-leader in this area,” she added.
Members of the SETsquared university spinout accelerator network across the SouthWest raised a record £616m (E716m, $870m) in 2020. This as up 40 percent on the previous year despite the Covid-19 pandemic.
The investments for companies in the SETsquared network were largely venture funding for start-ups and scale-ups, ranged from pre-seed/seed rounds of £250-500k through to the latest £118m funding round for Graphcore in Bristol.
SETsquared is a partnership of the UK universities of Bath, Bristol, Exeter, Southampton and Surrey that supports tech-based businesses from start-up to scale-up. Private investment accounted for 90 percent of the sum raised, with the remaining co-investment from publicly funded R&D grants and innovation loans.
“The record-setting £616m raise reflects the hard work of hundreds of committed founders and innovators across the SETsquared ecosystem who are developing technologies which will transform the future, from the way we live, travel and learn to the way we care for each other and our environment” said Simon Bond, Innovation Director at SETsquared.
“It shows that even during a global pandemic, strong ventures with good university connections, ambitious teams and the right support, will continue to raise investment.”
Bristol member LettUs Grow secured £2.35m in funding for their patent-pending indoor aeroponic growing facilities designed to address global food security and sustainability concerns.
“This investment gave us the platform to really accelerate in 2020 and scale-up the delivery of our game-changing technology to farmers across the country. We’re seeing rising demand from around the world for new technologies to help farmers grow crops in ways that mitigate against the effects of climate change and ever-increasing extreme weather events,” said Charlie Guy, Co-founder and CEO of LettUs Grow in Bristol.
SpaceForge in Wales is developing production methods for materials in space raised £600k funding from the Development Bank of Wales, alongside Bristol Private Equity Club and Innovate UK. The company benefited from an Investment Programme delivered by SETsquared and funded by Innovate UK which aimed to secure private Angel investment alongside public funding.
“It was amazing to receive this funding at such a critical time for our company. It enabled us to create jobs and start development of a new product called Fielder – an innovative method for satellite recovery, which can rendezvous with returning satellites and catch them rather than them burning up in the atmosphere and leaving harmful debris or ending up in the sea. The environmental benefits are huge, as we also have a method of refurbishing and reusing them,” said Joshua Western, CEO and Founder of SpaceForge.
“At its core, SETsquared’s partner universities have developed major research portfolios and this globally competitive concentration of research talent is attractive to founders, innovators and investors,” said Bond. “Looking ahead, I expect to see more venture capital deployed in our ecosystem. However, it is a contested space and our government’s own innovation target to grow the value of domestic R&D to 2.4 percent of GDP is part of a competitive international race. This is set to build-on the great UK success story of the ‘Golden Triangle’ and add several new investment funds from the major university collaborations of the Northern Accelerator in the North East, Northern Gritstone in the North West, MICRA in the Midlands and SETsquared in the South,” he said.
Bristol-based chip designer Graphcore is leading a European project to create a supercomputing framework for emerging AI applications in the real world.
The €2.6m three-year SparCity project will focus specifically on sparse AI, where there is not much correlation in the data. The tools developed during the project will be used to demonstrate the effectiveness of the framework in four real-world areas: computational cardiology, social networks, bioinformatics and autonomous driving.
SparCity is part of the broader EuroHPC Joint Undertaking (JU) launched in 2018 to increase Europe’s competitiveness in high-performance computing through the development of multiple next generation supercomputers.
Graphcore was one of the original proposers of the project, alongside Sabanci Universitesi in Turkey, Simula Research Laboratory in Norway, INESC-ID in Portugal and Ludwig-Maximilians-Universitaet Muenchen in Germany, with the coordination of Koç University (Turkey).
The company has raised $710m for the development, valuing the company at over $2bn and making it the best funded AI chip startup in the world.
Graphcore’s IPU chip and software technology is specifically designed for AI compute and includes characteristics such as the ability to execute many, very different calculations independently and in parallel, which are essential for sparse computations. This can reduce the power consumption but needed new hardware and software.
Sparsity is also supported at a software level with sparse kernels and libraries. These will be used and further developed during this project, along with performance and energy modelling, with the resulting models used to drive optimisations.
Researchers at the University of Bristol have used 3D printing to accelerate development of lab-on-chip diagnostic systems.
Microfluidic underpin lab-on-a-chip (LOC) technologies for rapid diagnostics, and the shape of the channels are key.
The team at Bristol used low cost 3D printing to produce the soft-lithographic moulds used for fabricating these microfluidic channels down to 100 microns wide. A 5000-piece physical library of mix-and-match channel scaffolds can be printed for less than $0.50.
“Previously, techniques for producing the soft-lithographic scaffolds/moulds (microfluidic channel patterns) were time-consuming and extremely expensive, while other low-cost alternatives were prone to unfavourable properties,” said Dr Robert Hughes who led the study. “This development could put LOC prototyping into the hands of researchers and clinicians who know the challenges best, in particular those in resource-limited settings, where rapid diagnostics may often have the greatest impact,”
“This technique is so simple, quick and cheap that devices can be fabricated using only everyday domestic or educational appliances and at a negligible cost around 0.05 percent of the cost of materials for a single microfluidic device. This means researchers and clinicians could use our technique and resources to help fabricate rapid medical diagnostic tools, quickly and cheaply, with minimal additional expertise or resources required,” said researcher Harry Felton.
“It is our hope that this will democratise microfluidics and lab-on-a-chip technology, help to advance the development of point-of-care diagnostics, and inspire the next generation of researchers and clinicians in the field,” said Hughes.
The next step for the team is to identify potential collaborators in both research and education to help demonstrate the impact this technology could have in both settings by developing and supporting outreach activities and applications for on-chip diagnostic testing.
A UK project including researchers from the University of Bristol is aiming to develop and test a remotely operated drone system for industrial and urban environments.
“As a leading research institution in 5G and beyond, we will provide expertise on the design of end-to-end network architecture for the future operation of drones,” said Professor Reza Nejabati, an expert in high performance and autonomous networks from the University of Bristol’s Smart Internet Lab. “Our experts will evaluate a combination of multiple 3GPP (4G and 5G), non 3GPP (WiFi), MEC and network slicing technologies in multi-operator settings with private and public operators. We are very well placed to train the next generation of engineers with unique and cross disciplinary skills in integration of telecommunication with drone systems.”
The consortium, led by specialist drone command and control system developer, sees.ai, includes 16 organisations such as BAE Systems, the UK’s National Air Traffic Control Services (NATS) and nuclear operator Sellafield.
BVLOS monitoring
The Beyond Visual Line of Sight (BVLOS) system will enable remote inspection and monitoring of industrial sites such as nuclear, construction and oil and gas, as well as urban sites in the public domain including road and rail and telecoms infrastructure, and live emergency services support.
The system uses AI on Nvidia GPU processors to enable drones to be flown under tight human supervision by pilots based in a central control room hundreds of miles away. Pilots can precisely execute complex missions remotely – even reactive missions (designed on-the-fly) and close-quarter missions encountering GPS problems, magnetic interference and degradation and loss of communications.
Operating safely in congested area is a major challenge, and it requires the consortium of aviation, aerospace, industrial and emergency service giants, to advance the system and integrate it into the wider aviation ecosystem.
“The Future Flight Challenge funding will accelerate us towards a future where drones fly autonomously at scale – high up alongside manned aviation and low down inside our industrial sites, suburbs and cities,” said John McKenna, CEO of sees.ai in West Sussex.
The Smart Internet Lab is among the technical contributors to the consortium, alongside Vodafone, The Met Office, Flock Cover and UAM Consult Ltd.
During these tests the system will be operated by two of the world’s leading drone service providers, Terra Drone and Sky-Futures or by the in-house drone teams at Sellafield, Network Rail, and the Lancashire Fire and Rescue Service.
Researchers in Bristol have built a multiplexed eight user quantum key distribution network with just eight receivers, a fraction of the number of devices currently required.
The international team of researchers has developed the first distributed network for sharing quantum keys in a breakthrough design.
So far, quantum key distribution has been point to point, even over satellites, but this limits the use in a network. The multiplexed photonic quantum key distribution (QKD) system, published in Science Advances, supports eight users and can be easily scaled up.
“This represents a massive breakthrough and makes the quantum internet a much more realistic proposition,” said Dr Siddarth Joshi, who headed the project at the Quantum Engineering Technology (QET) Labs at the University of Bristol, UK. “Until now, building a quantum network has entailed huge cost, time, and resource, as well as often compromising on its security which defeats the whole purpose.”
“Our solution is scalable, relatively cheap and, most important of all, impregnable. That means it’s an exciting game changer and paves the way for much more rapid development and widespread rollout of this technology,” he said.
Photonic QKD systems use entangled photons to ensure an encryption key is not intercepted.
“Until now efforts to expand the network have involved vast infrastructure and a system which requires the creation of another transmitter and receiver for every additional user. Sharing messages in this way, known as trusted nodes, is just not good enough because it uses so much extra hardware which could leak and would no longer be totally secure.”
The team includes researchers from the UK’s University of Leeds, Croatia’s Ruder Boskovic Institute (RBI) in Zagreb, Austria’s Institute for Quantum Optics and Quantum Information (IQOQI), in Vienna, and China’s National University of Defence Technology (NUDT) in Changsha.
The team used multiplexing to develop an eight user system with eight transceivers, rather than the 56 that would previously be needed for each user to have a point to point link.
The receivers were connected to optical fibres via different locations across Bristol and the ability to transmit messages via quantum communication was tested using the city’s existing optical fibre network.
“Besides being completely secure, the beauty of this new technique is its streamline agility, which requires minimal hardware because it integrates with existing technology,” said Joshi.
The network was created within months for less than £300,000, enabling secure networks for a fraction of the cost today. The system also features traffic management, delivering better network control which allows, for instance, certain users to be prioritised with a faster connection.
“With these economies of scale, the prospect of a quantum internet for universal usage is much less far-fetched. We have proved the concept and by further refining our multiplexing methods to optimise and share resources in the network, we could be looking at serving not just hundreds or thousands, but potentially millions of users in the not too distant future,” said Joshi.
“The ramifications of the COVID-19 pandemic have not only shown importance and potential of the internet, and our growing dependence on it, but also how its absolute security is paramount. Multiplexing entanglement could hold the vital key to making this security a much-needed reality.”
The research received funding from the Quantum Communications Hubs of the Engineering and Physical Science Research Council (EPSRC), Ministry of Science and Education (MSE) of Croatia, and the Austrian Research Promotion Agency (FFG).
Researchers at the University of Bath in the UK have developed the first fuel cell that can be stacked in a printed circuit board for wearable designs.
Glucose Fuel Cells (GFCs) generate power from any body fluid at room temperature, including sweat for wearables and blood for embedded medical devices
The team led by Carla Gonzalez-Solino at the Centre for Biosensors, Bioelectronics and Biodevices (C3Bio) at the University of Bath developed an integrated arrays of GFCs and successfully demonstrate their operation at physiological concentrations of glucose.
Each GFC consists of a porous gold anode and a Pt/Au cathode in a single layer, and generates a maximum power of 14.3 μW/cm2 (in 6 mM of glucose) a 297mV, with a linear response to glucose within a concentration range that includes both low and high glucose levels.
The challenge for individual GFCs is the low voltage output. So the team also connected four GFCs in parallel in a stack on a PCB. This generated between 1.4V and 0.9V.
Each board measures 42.5 mm x 34.5 mm consisted of four rows that include a circular electrode (geometric area: 1.54 mm2) used as the anode, and a crescent electrode, used as the cathode (geometric area: 7.22 mm2).
To demonstrate meaningful energy harvesting, the four GFC stack was connected to a commercial off-the-shelf power management system using a BQ25504 PMIC from Texas Instruments that can handle the low output voltage. The BQ25504 system is designed to operate with input voltages as low as 100 mV, a range that covers most fuel cells. It has a built-in Maximum Power Point Tracking (MPPT) function that finds the open circuit potential (OCP) of the fuel cell and sets the operating point by varying the effective load impedance seen by the fuel cell to around 80 percent of this voltage.
The OCP is sampled for 256 ms, which, for the GFCs proposed in this work, is sufficient for the cells to reach full OCP. The BQ25504 system also includes a battery management system, which was connected to a storage capacitor. Both the 4-GFC voltage and the voltage over the energy storage element were continually logged using a Pico datalogger to record the voltage over time.
Three leading Bristol-based companies are attending the global mobile tech conference
Companies from the South West region are demonstrating their world-beating technologies at Mobile World Congress (MWC) in Barcelona later this month – an event that brings together leading technology companies and telecoms operators from around the world.
Bristol-based XMOS Semiconductor is showcasing its far-field voice capture systems. These are used in the voice-enabled stereos, smart TVs, soundbars, set-top boxes and digital media adapter markets which use the company’s innovative processor.
The XMOS technology includes the world’s first stereo acoustic echo cancellation (AEC) far-field linear microphone array solution. This is based on a voice processor which delivers dual channel full stereo. Its VocalSorcery technology can identify individual speakers or conversations in a crowded noisy audio environment. This could be used for example to diarize voice conferences, and give a full transcript, by speaker of multi-person conversations, and ensure that all speakers on a conference call are heard with equal volume.
“We’re demonstrating our next generation of source separation algorithms, VocalSorcery, which solves what is sometimes described as the ‘Cocktail Party Problem’ and enables commercial solutions for improved conference calls and in-car phone calls,” says Mark Lippett, President and CEO at XMOS.
“With our next generation of algorithms we are confident that we have the most comprehensive portfolio of voice products available today.”
At the same time, Zeetta Networks‘ NetOS software-defined networking technology has been nominated as the Best Network Software Breakthrough at the show.
NetOS makes a 5G wireless network fully programmable, opening new opportunities for smart cities and smart venues. It is already being used at Bristol’s Ashton Gate sports stadium as part of a live ‘data lab’.
The category of Best Network Software Breakthrough is new this year and aims to highlight outstanding software innovations leading to dramatic changes in network costs, functionality and business cases.
“We are delighted that our NetOS technology has been nominated for a world-class GLOMO award,” says Vassilis Seferidis, CEO of Zeetta Networks. “Our vision at Zeetta Networks has always been to create software that transforms the network into a dynamic, programmable platform that allows our customers to maximize the value from their networking assets. NetOS is a core component in delivering dynamic, multi-tenancy and multi-vendor networks and has already been deployed successfully in production networks, working across multiple technologies whether fibre, packet switched Wi-Fi or the Internet of Things.”
NetOS is also a central component to the ‘Bristol is Open‘ Smart City testbed and to the UK Government’s 5G Hub, which is testing out network virtualisation and slicing for 5G services.
5G future
Blu Wireless Technology (BWT) will also be demonstrating its millimetre 5G wireless technology at the show. The company recently joined the Telecom Infrastructure Project (TIP) as part of the recently established mmWave working group to develop the latest 60GHz networking technology.
TIP is the engineering-focused initiative co-chaired by Facebook and Deutsche Telekom, bringing together expertise from pioneering technology companies.
“Our mission goes beyond simply delivering advanced technology to our customers, but rather providing deep domain expertise, from a technology and market perspective,” says Henry Nurser, CEO of BWT.
“Being amongst this forward-thinking, highly esteemed collection of companies gives us access to shared ideas and the opportunity to play an integral part in the future of this rapidly emerging global technology ecosystem.”
Global tech companies back Bristol’s leading drone competition and the latest research proposals on the use of drones in the city
The MAAXX Europe 2018 drone racing competition returns to the region on 23 and 24 March with triple the flying area at the Exhibition and Conference Centre at UWE Bristol.
Working with leading chip maker NVIDIA, phone and system maker Huawei and the Aerospace Bristol museum as part of their celebration of the RAF’s 100th anniversary, the flying area now has two large arenas to test out the latest drone technologies.
Check out what MAAXX Europe was like at last year’s event in the video below:
With 12 industry and university teams, the event aims to push the boundaries of control systems for autonomous aircraft. There’s an overnight build-a-drone event with significant support from Huawei and other companies along with teams from the leading UK and EU universities.
The industry day on Friday 23 March will also feature a research poster exhibition from some of the brightest post-graduates around.
MAAXX Europe’s co-organiser, High Tech Bristol and Bath (HBB), is also applying to the NESTA Flying High Challenge. This four-month consultation would provide the framework for a future bid for funding to examine the use of drones in urban situations.
“NESTA is looking for five cities in the UK to be the centre for all things drone,” says John Bradford, CEO of HBB. “We are looking at infrastructure monitoring, contested airspace around the port at Avonmouth and the airport as well as emergency and health response. Then there’s a crowd safety and management around large events such as the Harbour Festival,” he adds.
You can find out more about MAXX Europe and register for free tickets via the MAAXX Europe 2018 website. For updates on Bristol’s involvement in the Flying High challenge, you can follow HBB on Twitter here: @hbb_cic.
Researchers at the University of Bristol have been able to trap objects larger than the wavelength of sound in a beam. This opens the door to the manipulation of drug capsules or even controlling tiny surgical implements within the body in sterile environments.
“Acoustic tractor beams have huge potential in many applications. I’m particularly excited by the idea of contactless production lines where delicate objects are assembled without touching them,” says Bruce Drinkwater, Professor of Ultrasonics at the University’s Department of Mechanical Engineering.
Current theory says these tractor beams were fundamentally limited to levitating small objects as all the previous attempts to trap particles larger than the wavelength had been unstable, with objects spinning uncontrollably.
Instead the team used rapidly fluctuating acoustic vortices, which are similar to tornadoes of sound, to create a stable core. They were then able to increase the size of the silent core allowing it to hold larger objects. Working with ultrasonic waves at a pitch of 40kHz, the researchers held a 2cm polystyrene sphere in the tractor beam (pictured left).
This sphere is over twice the acoustic wavelength and is the largest yet trapped in a tractor beam. The research suggests that, in the future, much larger objects could be levitated in this way by boosting the power of the ultrasound.
“Acoustic researchers have been frustrated by the size limit for years, so it’s satisfying to find a way to overcome it. I think it opens the door to many new applications,” says Dr. Asier Marzo at Bristol’s Department of Mechanical Engineering.
Ultrasound is a key area for Bristol. The University team has previously shown smaller objects being moved around by the beams, while Ultrahaptics in the city is using focused ultrasound beams to provide the feeling of touch in mid-air.
A trial is starting in Bristol this month to use connected vehicles to monitor air pollution in real time.
Bristol Waste, which operates the refuse and recycling service in Bristol, is working with US connected car company Tantalum and data researchers from Imperial College London on “Air.Car” which provides highly accurate, real-time feedback on the levels of nitrous oxide (NOx), a key pollutant.
According to research by US scientists, excess emissions of NOx exhaust gases can be linked to 38,000 premature deaths worldwide and it is a key measure for meeting UK and European pollution limits.
“We run a large fleet of vehicles across the city of Bristol and understanding the environmental impact of our operation is a key part of our sustainability plan and our commitment to contributing to a cleaner and greener Bristol,” says Tracey Morgan (pictured centre right), Bristol Waste Company’s Managing Director.
“The data from this trial, which will include at least 40 of our heavy vehicles, will enable us to make more informed decisions around which of them we use, at what times and on which routes to help us manage that impact.”
This is part of a 1,000-vehicle trial that also includes the University of Oxford, where units are being installed in diesel vehicles to estimate real-time NOx emissions in major cities across the UK.
The £2m project started last July and taps into the On Board Diagnostic (OBD) port on the vehicle to access the engine control unit to gather data, and the data will be used to develop a tool from Tantalum to provide a detailed understanding of the environmental impact of vehicles and the tools to minimise it.
Ozgur Tohumcu, CEO of Tantalum tells us: “There’s a real buzz around how we can use data cleverly to improve people’s lives. It will be transformative for managing and reducing the silent killer, NOx, in the world’s towns and cities.”
2018 is set to be a stellar year in the region and there are eight tech companies to keep an eye on.
Kudan
With engineering in Bristol and marketing in Tokyo, Kudan is making significant steps with its Simultaneous Localisation and Mapping (SLAM) technology which helps driverless cars and drones navigate more accurately.
It’s currently dealing with major car makers for both mainstream and driverless cars, major Asian mobile phone makers and large drone makers who are all driving the adoption of the designs.
KETS Quantum Security
Bristol is a global hub of expertise in quantum technology, so it’s no surprise that one of the companies on the list for 2018 comes from the Quantum Entrepreneur’s hub.
KETS Quantum Security is providing photonic security technology that is small and light enough to be used on drones for uncrackable communications. It has won several awards and accelerator deals for the commercialisation of the technology.
Dyson
Dyson is a big name in home appliances and it’s now set to expand its expertise and success to electric cars. Its car and battery research and development centre in Malmesbury is set to shake up the automotive world and its design centre in Bristol is leading the way for developments in the Internet of Things.
Amazon FreeRTOS
Amazon already has a presence in Bristol with its cloud team, but its importance is stepping up a gear with the release of the Amazon FreeRTOS.
The world’s most popular real-time operating technology was developed in Bristol and with the backing of Amazon it’s set to be even more significant, allowing the easy connection of sensors and controllers to cloud services in the Internet of Things.
UltraSoC
Cambridge-based UltraSoC has just opened its second office, tapping into the tech expertise in the Bristol and Bath region.
Its team started out developing analytics hardware that is designed into chips for development. This is now a way of gaining invaluable insights into all activities across the Internet of Things.
Cerberus Labs
Cerberus Labs taps into the skills of highly experienced engineers from ST Microelectronics. Their expertise in encryption and chip design has led to innovative security chips for a range of IoT applications, especially to secure the communications between vehicles.
Not only is the company providing the hardware designs but it’s also offering network support for messaging between the chips.
Reach Robotics
We are also saying welcome back to Reach Robotics after time in the US at a leading accelerator. Its MekaMon battling robots were launched in November last year after the company raised $7.5m for the bot’s development. You can check them out in action in the video below:
The team is now driving manufacturing and growth and is planning for further expansion this year. A deal to sell its robots in Apple stores will also see a boost during 2018.
Silas Adekunle, CEO of Reach Robotics previously told us: “It was important for us here at Reach Robotics to remain loyal to Bristol, given the support we’ve already had from Bristol Robotics Lab and UWE Bristol.”
Compound Semiconductor Catapult
While not a company, the £50m Compound Semiconductor Catapult in Newport starts operations this year, developing and enhancing the latest technology in chips for wireless chargers, more efficient power systems and next-generation radio-frequency systems for 5G and 6G equipment.
Aiming to have 2000 researchers and developers just across the Severn Bridge (which will eliminate tolls later this year), the national research centre will be just 20 minutes from Bristol and a huge boost to technology development in the region.
A new laboratory at UWE in Bristol is set to combine traditional print techniques with cutting-edge sensor and materials technology.
UWE Bristol’s Centre for Fine Print Research (CFPR) is set to start a five-year £1.5m project in January on new designs for print heads for commercial printers and the development of the next generation of inks with distinctive properties and new ways of printing.
This could lead to new applications such as a T-shirt that can warn its wearer when dangerous chemicals are in the air, or pharmaceutical packaging with ink signifying when pills have been tampered with.
The lab will be run by Dr Susanne Klein, who used to work for printer maker Hewlett Packard as a senior researcher at its labs in Bristol.
The research will combine the CFPR’s knowledge of traditional photomechanical printing methods, such as Lippmann and Woodbury, and use the techniques for use on a 2.5D printer, which creates texture as part of an image on a substrate.
Using her expertise in colloidal chemistry (working with particles suspended in a solution), and liquid crystals, Klein will also develop specialist inks that can change colour in certain environments.
Such properties could mean a T-shirt print might be able to detect chemicals in the environment that have a proven link to cardiovascular disease, and change colour to warn the wearer. Similar ink on the garment could also react to heat and change colour when the wearer has spent a long time in the sun.
Smart inks could also help manufacturers trace a product as it passes through the supply chain, or curb counterfeiting.
“There are lots of problems with counterfeiting of pharmaceuticals and sometimes products are found to be counterfeited where the packaging is identical to the original,” said Dr Klein. “We will produce packaging with printing ink that will change colour every time it passes through and is authorised at a different stage on its way to the customer.
“Another application could be in the case of food that needs to remain cold in its packaging. The technology could lead to labels that react to heat, switch to another colour if they have warmed and stay that colour,” she said.
“The printing landscape is changing and I think our research will contribute to that, but the industry is traditional with its own way of doing things, and no big printer will make any radical changes. Our plan is to feed in little advances, bit by bit, so that commercial printers can adapt slowly to new technologies.”
The funding will provide £300,000 per year for five years to the University and Klein will set up a team comprising a post-doctorate student and a technician to work with the CFPR to develop this new printing approach.
“This funding is unprecedented nationally in an art school environment,” said Professor Carinna Parraman, Director of the CFPR. “This is a unique opportunity to pair an experienced material scientist, coming into academia with industrial and manufacturing process knowledge and skills, with the CFPR’s expertise in photomechanical processes invented in the 19th century.”
The CFPR has already been working with advanced 3D printing technology with a wide range of materials including ceramics.
Researchers are rolling out a network of basestations across Bristol to communicate with driverless cars.
The basestations will use the latest Vehicle-to-Infrastructure (V2I) technology with a Bristol twist. Instead of using expensive dedicated hardware and software, the researchers have used low cost commercial Wi-Fi chips and their own software.
The technology can also be used with sensors on the infrastructure.
IQD Frequency Products in Crewkerne, Somerset, has been bought by German component maker Würth Elektronik.
The 44 year old company makes quartz crystals and oscillators that provide the timing for all kinds of electronics and along with its US subsidiary IQD Frequency Products Inc in Palm Springs will be part of the Würth Elektronik eiSos Group.
IQD is among the leading manufacturers of frequency control devices in Europe, and is active in over 80 countries. The deal will enable the company to make even greater investments in the further development of technologies and products, says Würth.
“With IQD our group has now acquired a highly innovative company with cutting-edge technologies and component solutions which are a logical extension of the range of products we offer. We are particularly pleased that we’re now able to offer valuable extensions for IoT, WiFi, GPS and 5G applications,” said Oliver Konz, CEO of Würth Elektronik eiSos Group.
IQD develops, manufactures and markets quartz crystals, oscillators, VCXOs, TCXOs, OCXOs, GPS-synchronised OCXOs and rubidium oscillators. The company also offers product solutions built to customer’s specifications.
“In our eyes, Würth Elektronik eiSos is the ideal partner for us,” said Paul Fear, former Group Managing Director of IQD. “Supported by Würth Elektronik eiSos’ global sales strength, IQD will be able to continue its growth whilst at the same time expanding its range of innovative product solutions.”
Amazon has tapped SouthWest technology for the embedded software to control billions of devices in the Internet of Things (IoT).
The company has launched its own version of the world’s most popular embedded operating system, FreeRTOS, developed in Bristol by Richard Barry who worked for Wittenstein High Integrity Systems (WHIS).
Last year Barry joined Amazon as a principal engineer and, as a result, the FreeRTOS kernel version 10 is now under the MIT licence – allowing it to be used freely (instead of its previous and more restrictive GPLv2 licence).
Simplified licensing has long been requested by the FreeRTOS community and the choice of the MIT licence was based on the needs of the embedded systems community. Open source Amazon has also developed its own version, Amazon FreeRTOS, which is based on the FreeRTOS kernel and adds support for Amazon Web Service (AWS) and IoT use cases. This includes software libraries that make it easy to securely connect devices to the cloud and on a local network. This works on boards developed by STMicroelectronics which also had a large embedded technology centre in the region for many years.
SEGGER had just completed a new linker just when Somnium’s technology came onto the market, but was sceptical of the technology claims. It is at odds to point out that its linker is complete and contains no technology derived from Somnium.
There are no firm plans to unite the two linkers right now, and the company is now looking to pick up Somnium customers (and presumably offer them the new linker).
A major Silicon Valley investor, Sequoia Capital, has identified Graphcore in Bristol as the world’s leading chip designer for machine learning (ML) and artificial intelligence (AI), backing the startup with $50m in a third round of funding to bring the total to over $110m.
Sequoia has previously backed companies such as Apple, Cisco, Google, NVIDIA and Microchip. “Machine intelligence will cause an explosion of new applications and services that will transform every industry. We believe Graphcore’s product architecture, team and early market interest make it the best positioned new entrant in this market,” said Matt Miller, the partner at Sequoia who will join the Graphcore board of directors.
The funding will be used to scale up production of its Intelligence Processing Unit (IPU) chips and accelerator cards, building a community of developers around its Poplar ML software platform, driving Graphcore’s extended product roadmap, and investing in its Palo Alto-based US team to help support customers.
The company is planning to ship its first IPU devices to early access customers at the start of 2018, slightly later than its original plan of the end of 2017. Early benchmarking has shown 10x to 100x speed up in running AI algorithms and the ability to scale across many separate accelerator cards.

The University of Southampton is set to benefit from two major investments in research partnerships that will strengthen the links between the UK’s research base, industry and business partners. Both investments show the pivotal importance of engineering and the physical sciences to the country’s continued development as a global research and innovation leader.
The first is a set of new ‘Prosperity Partnerships’ which will receive £31m of government funding from the Engineering and Physical Sciences Research Council (EPSRC) and the Industrial Strategy Challenge Fund (ISCF). This is matched by a further £36m from partner organisations in cash or in-kind contributions, plus £11m from universities’ funds, totalling £78m in all.
Ten universities will lead on 11 projects that range from future networks for digital infrastructure to offshore wind. Over five years, the University of Southampton’s Silicon Photonics Group (part of the Optoelectronics Research Centre – ORC) will receive £2.7m from the EPSRC, working with its partner Rockley Photonics – who will contribute a further £2m. The University will provide an additional £148,000.
The money will support research into the use of silicon photonics technology within communications networks in data centres. The aim is to improve their speed and energy efficiency by changing the datacentre architecture. Silicon photonics is an emerging technology which uses optical signals to transfer data between computers, servers and the wider world.
“Dr Andrew Rickman, Chief Executive Officer of Rockley Photonics, is the world’s leading entrepreneur in this field. We have a long history of working together in many different ways, since 1989, and this collaboration is almost the perfect fit for the remit of the Prosperity Partnerships – a truly mutual relationship between university and industry,” said Graham Reed, Professor of Silicon Photonics at Southampton. “Our expertise and facilities offer a unique environment for silicon photonics research and innovation. One of the world’s most pressing problems is how to handle our relentless desire for more data, and we are striving to make significant improvements. The Prosperity Partnership is the perfect vehicle for our work with Rockley Photonics; it enables a relatively young, growing company to invest in university research at an early stage.”
The second EPSRC investment is £60m for 33 universities to advance their Impact Acceleration Accounts (IAA). The University of Southampton will receive almost £3m for IAAs over three years.

“Previously, techniques for producing the soft-lithographic scaffolds/moulds (microfluidic channel patterns) were time-consuming and extremely expensive, while other low-cost alternatives were prone to unfavourable properties,” said Dr Robert Hughes who led the study. “This development could put LOC prototyping into the hands of researchers and clinicians who know the challenges best, in particular those in resource-limited settings, where rapid diagnostics may often have the greatest impact,”
