Transparent transistors have been fabricated around glass tubes of 2mm diameter, at Oregon State University. It replaces a polymer transistor, printed on film and wrapped around the tube, which fell apart when tested as part of an artificial pancreas – a catheter intended to detect blood sugar levels and transmit the information to a wearable ...

An all-optical four port isolator has been demonstrated by the University of Science and Technology of China (USTC), without the use of magnetic fields. For the circulator (see diagram) the signal light incident from the ports 1, 2, 3 and 4, exits from the ports 2, 3, 4 and 1, respectively, constituting a 1-2-3-4-1 circular ...

The life of lithium-sulphur batteries can be extended from ~100 to >200 charging cycles, according to researchers from Purdue University. This compares with ~600 cycles for common laptop Li-ion cells and far more from specialist types. When charge is applied to Li-S cells, lithium ions migrate to the sulphur and lithium sulphide is produced. A ...

Diodes Inc has created a family of two-pin constant current chips that can work at up to 400V. Intended to control strings of LEDs running direct from rectifier mains, and called AL5890, it is available 10mA, 15mA, 20mA, 30mA, and 40mA variants “Its simple two-pin design means it can be inserted directly in the LED ...

In a blow to Arm’s multi-decade effort to get its cores into servers, Qualcomm is reported by Bloomberg to be giving up on its Arm-based server chip programme. Qualcomm will either close its server chip operation or sell it. Cavium, which announced its latest Arm-based server chip ThunderX2 on Monday, could be interested, as could ...

Researchers at the University at Buffalo School of Engineering and Applied Sciences have developed an inexpensive sniffer IC which they hope will be be used in police detection systems for drivers who are under the influence of drugs. They say the chip can detect drugs from samples of blood, breath, urine or saliva. The chip ...
