Rubbery transistors make stretchy logic and touch sensors

University of Houston have created an elastic semiconductor with 8.57cm2/Vs charge carrier mobility, and then made transistors, logic and a sensor array from it. Carrier mobility is largely retained when stretched by 50%. The semiconductor concerned is poly(3-hexylthiophene) – ‘P3HT’. This is not the first time the team has made stretchy transistors from this material, but it ...

Tiny 30V 4.5A 25mΩ photo-relay is 3.4 x 2.1 x 1.3mm

Toshiba has released three tiny photo-relays in a 3.4 x 2.1 x 1.3mm package called P-SON4. Back-to-back output mosfets means that AC voltage and current switching is possible. “Each have OFF-state output terminal voltage ratings and ON-state current ratings that are comparable to larger SOP-packaged devices,” according to the company. “Their 7.2mm2 (typ.) mounting area is approximately ...

Add noise for clearer signals

Adding just the right amount of noise can improve signal to noise ratio in certain non-linear systems. The effect is known as ‘stochastic resonance’, where mixing of noise and signal in the system non-linearity can sometimes push a previously buried signal just above the noise floor. Now researchers at Penn State University have exploited it ...

Better x-ray photon detector for CT scanning

French research lab CEA-Leti has created a novel x-ray photon-counting detector module (PCDM) for CT scanners, based on cadmium telluride (CdTe). CT scanners computer-process combinations of many X-ray images taken from different angles to produce 3D data. “Current x-ray CT scanners produce images with energy-integrating detectors [EIDs], which are based on indirect conversion technology: X-ray photons are first ...

Arm’s Cortex-R82 embedded processor for big-memory products

Arm has announced its first 64bit, Linux-capable Cortex-R processor, designed for computational storage solutions. Called the Cortex-R82, it is a successor to the 32bit Cortex-R5 and Cortex-R8 processors used in solid-stare drives. “These systems have historically required less then 4Gbyte of DRAM and addressable space, and have not had a need to run Linux,” according to ...
