Time synchronisation for energy efficient sensors
24.01.2017 - 23:53
One of the key ideas behind the IoT is the use of sensor networks to gather data. But when there may be thousands of sensors in a network, each sensor needs to be as low cost as possible. However, low cost sensors often have limited energy and computing capacities, so making the most of these limited resources is important and Austrian resear...
Topological photonic crystal made of silicon
24.01.2017 - 23:41
A new principle, in which electromagnetic waves, including light, can propagate on the edge of a 2D photonic crystal without being scattered, has been developed by researchers from Japan’s International Center for Materials Nanoarchitectonics (MANA) and the National Institute for Materials Science (NIMS). It was known that scattering of...
Update - New class of topological metals with special electronic properties
24.01.2017 - 23:36
A new class of metals, revealed by researchers at Princeton, Yale, and the University of Zurich, possesses electronic properties that could help scientists find other, similarly-endowed materials. The study described the class of metals based on their symmetry and a mathematical classification known as a topological number, which is predictiv...
Mechanical pixels for energy efficient colour displays
24.01.2017 - 23:17
Researchers from TU Delft and Graphenea in Spain have found a way to create what they call 'mechanical pixels'. While the pixels, created using balloon like structures, do not emit light, they could be used in energy-efficient colour displays for a range of applications. The 'pixels' are 13µm wide circular indents in sil...
Predicting noise in photonic circuits
24.01.2017 - 23:11
Researchers at the Moscow Institute of Physics and Technology believe it will be possible to predict accurately the level of noise caused by the amplification of photonic and plasmonic signals in nanoscale optoelectronic circuits. The scientists say their approach could be used not only to evaluate the ultimate data transfer rates in emerging op...
Wireless sensor module for range of apps
07.01.2017 - 21:16
A wireless sensor module developed by Samtec and STMicroelectronics is said to be a production-ready solution that allows engineers to sense and measure inertial, environmental and acoustical parameters remotely. Measuring 13.5mm x 13.5mm, the module contains an accelerometer, gyroscope, magnetometer, pressure sensor and microphone – pa...
Process to print flexible e-stickers
07.01.2017 - 20:58
A process developed by KAUST prints silicon-based networked sensors on to soft, sticker-like surfaces that can be attached anywhere. Pressure-sensitive ‘e-stickers’ contain all the functionality of traditional silicon circuits, but can be fabricated into complex, flexible shapes such as butterflies. Flexible printed circuits requi...
MCUs for automotive radar systems
07.01.2017 - 16:16
Renesas Electronics has unveiled a series of MCUs intended for use with automotive radar systems. The RH850 based parts are said by the company to deliver the performance and features required for future advanced driver assistance systems (ADAS) and autonomous driving vehicles. Looking to address a range of needs, Renesas has launched the RH8...
Nanowire inks enable printable electronics
07.01.2017 - 15:59
By suspending tiny metal nanoparticles in liquids, Duke University scientists are creating conductive ‘inks’ that can be used to print inexpensive, customisable circuit patterns on any surface. According to the researchers, printed electronics currently have one major drawback: for the circuits to work, they first have to be heate...
Diamondoids to make wires three atoms wide
07.01.2017 - 15:40
Scientists at Stanford University and the US Department of Energy’s SLAC National Accelerator Laboratory have discovered a way to use diamondoids – the smallest possible bits of diamond – to assemble atoms into electrical wires just three atoms wide. The technique could potentially be used to build wires for a range of appli...
