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 ...

The wireless cooking temperature sensor device “NICK” using all-solid-state batteries (left), and the Maxell’s all-solid-state battery “PSB401010H” mounted on the circuit board (enlarged ...

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 ...

Wanting to know the outside temperature, [Jamie Maloway] built his own temperature sensor that can be read with a Bluetooth device. Let’s take a tour of the hardware above from right to left.… ...

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 ...

Diamonds may be forever… and they may also be at the heart of a precision quantum-based current sensor for EVs.
