Many wireless applications rely on remote battery-powered electronics, and with the explosion of IoT these are set to be numbered in billions. Power for these sensors, meters, remote data concentrators, gateways and more, is often only practically available from an integral battery which may need to be physically small with consequent limited energy storage. This makes low power consumption critical, and often designers will look for additional solutions to extend battery life and reduce downtime.

In the latest post on Engineers' Insight, Martin Keenan explains how supercapacitors can be deployed in conjunction with batteries to extend their operational life and reduce maintenance and replacement costs.
