An IoT battery to last a billion years

0 Posted by - 1st November 2016 - Technology

The widespread deployment of Internet of Things devices is being held back by a significant limiting factor: battery life.

Wiring field sensors and devices to a power source defeats the objective of the IoT, so batteries that support the required algorithm processing and the sending of data packets need to be deployed alongside them.

But if devices are to be embedded in parking spaces, pavements, on the top of high-rises and in sewers underground, the potential cost around first finding and then replacing those sensors’ batteries with any regularity starts to become prohibitive.

Researchers at the University of Cambridge in the UK last week published a paper that could solve the problem completely with a way to power transistors that doesn’t require a battery at all.
