Dr Michael Kraft and his team at the University of Southampton’s School of Electronics & Computer Science (ECS) are working with a Belgian company, Melexis, to develop innovative control and interface systems to improve the performance of existing micromachined sensors.
In this three-year research project, Melexis, a growing Belgium-based company, which produces integrated semiconductor device systems for use in the automotive market, has supplied micromachined accelerometers (a device for measuring acceleration) so that the team can assess and improve its performance using their interface and control circuits
‘There is a huge, just recently emerging demand for higher performance inertial sensors for intelligent automotive systems and many others,’ commented Dr Kraft. ‘Six to eight airbags are standard already; they need to be deployed by accelerometers that accurately sense the impact of a crash.’
According to Dr Kraft existing commercial accelerometers may not meet these increasing performance specifications. His research programme will take the Melexis accelerometer and use advanced electronics and control engineering to make it better, more versatile and easier to integrate at a system level.
‘This research suggests a radically different approach to improve the performance of these sensors, namely to work on the electronic interface and control systems aspects of these sensors, rather than the microfabricated sensing elements themselves,’ said Dr Kraft.
The prime beneficiaries of this research will be companies supplying sensors for automotive safety systems. Other applications such as for GPS (Global Positioning System) back-up systems, virtual reality systems, inertial navigation and guidance, and seismology, also require sensors with very high specification characteristics.
‘Little research has been done in this field, yet there is huge potential to make a real impact,’ said Dr Kraft. ‘With this approach it should be possible to develop a very versatile interface chip that can be used with a range of micromachined sensors.’

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
