A group of Dutch researchers have created an interesting sensor solution that needs no battery for power. The tiny sensor is two square millimeters and is a wireless temperature sensor.

The Pyros-3GT2-DWB from Farsens S.L., San Sebastián, Spain, is a battery free RFID sensor tag capable of transmitting a unique identifier and the associated temperature measurement data to a ...

With its radio receiver and radio transmitter consuming just 0.85 mA and 2.1 mA, respectively, the GTI-ATM3330e Bluetooth module can extend battery life in a broad range of IoT applications. To assist ...

Ultra-low-power ZigBee-based wireless mesh networks, powered by a variety of energy-harvesting technologies, make it possible to create the first truly wireless and battery-less sense and control ...

They've built an extra-small (2 square millimeters) wireless temperature sensor that gets its power from the radio waves that make up its wireless network.

The battery module presented was constructed, assembled and tested in order to demonstrate measures for spatial and temporal temperature homogenisation. As such, conventional aluminium cooling plates ...
