New temperature sensor runs on near-zero power

In a groundbreaking invention, researchers at the University of California, San Diego have engineered a temperature sensor that runs only on 113 picowatts, around 10 billion times less power than a watt.

The near-zero sensors open up the possibility of a new set of devices that could harvest energy from low-power sources like ambient temperature or body heat, writes UC San Diego.

Hui Wang, an author of the study, says the new sensor can help build wearables and electronic systems that will stay live for years with just a tiny battery, notes Engadget.
