Exploiting a quantum principle in a novel way, researchers at the US National Institute of Standards and Technology (NIST) have created a miniature thermometer that works below 1K with errors less that 14mK and a response time of 5ms. Two of the novel temperature sensors (top right, bottom left) are bonded to a chip under ...

Microchip has released 8bit PIC18 MCUs that can transmit and receive data through CAN bus Flexible Data rate (CAN FD) bus. It has created the family, called PIC18 Q84, for transporting sensor data to a CAN FD bus without the need for gateways or sophisticated network switching techniques. “CAN FD will play a critical role in ...

In what might be the lowest power sensor ever deliberately made, engineers at Washington University in St Louis have used quantum tunnelling as a data logger to keep a record of vibration. The recording device is a floating gate in a modified transistor structure. When charged, the floating gate is designed to gradually discharge through Fowler-Nordheim tunnelling. ...

At Electronica, Grenoble-based Teledyne e2v revealed a 12bit 11Gsample/s ADC proof-of-concept “able to deliver performance parameters that are beyond the scope of anything currently on the market”, it claimed, “It can achieve SHF [super-high frequency] direct sampling, reaching all the way into the Ka frequency band. Called EV12PS640, it was demonstrated alongside the recently announced ...

Researchers from the University of Bristol have made a detector to measure quantum features of light in more detail than ever before, with a sensor “clocked at an order of magnitude faster than the previous state-of-the-art,” said Bristol. It was used to measure the unique properties of ‘squeezed’ quantum light at record high speeds, according to ...

For the safe transport of vaccines, drugs and medical samples, Timestrip of Cambridge has developed a tell-tale temperature monitor that permanently indicates if storage temperature rules have been transgressed. Called TC489, it uses a set of three LEDs to provide a clear, non-reversible indication of upper and lower temperature breaches as well as normal operation, ...

UnitedSiC has added four silicon carbide junction barrier Schottky (JBS) diodes complement its SiC FET and JFET transistor products. The UJ3D 1,200V and 1,700V devices are part of the company’s 3rd generation of ‘merged-PiN-Schottky’ (MPS) diodes. The Vf x Qc figure-of-merit is emphasised by the company. Picking one of the four at random, this typically ...

Renesas has teamed up with consultancy Altran to develop a social distancing wearable platform based on ultra-wideband (UWB) radio technology – earlier this year Renesas licensed UWB technology from fabless chip firm 3db Access. Worn like a wristwatch, it combines a S128 MCU with secure ranging based on UWB. “Unlike other social distancing wearables based ...

Mallory Sonalert has a series of 31mm diameter indicator lights in one, two or three colours selected from red, yellow and green. Called Stacklights, they mount with an M22 thread through a 22.5mm hole. Some versions have the lights just above the mounting surface and some are extended 100mm above the mounting surface (see photo, ...
