‘Near-zero-power’ temperature sensor could make wearables, smart devices less power-hungry

Electrical engineers have developed a temperature sensor that runs on only 113 picowatts of power — 628 times lower power than the state of the art and about 10 billion times smaller than a watt. This near-zero-power temperature sensor could extend the battery life of wearable or implantable devices that monitor body temperature, smart home monitoring systems, Internet of Things devices and environmental monitoring systems.
