RVmagnetics' MicroWire technology offers the smallest passive sensor, facilitating deep, internal sensing for advanced ...

Sensor-based passive RFID tags have been on the market for just a few years, but according to U.K.-based market-research firm IDTechEx, they have accomplished sufficient growth in niche markets that ...

“We wondered whether we could repurpose RFID tags to do battery-free sensing and tracking,” says Nagarjun Bhat, a Ph.D. student in electrical engineering and lead author of a new study. Data is power.

Our October print edition includes a feature article on modular systems for IC test, and our July issue included a special report on bench and modular instruments for semiconductor test applications.

The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.
