A new power saving chip developed by engineers at the University of California San Diego could significantly reduce or eliminate the need to replace batteries in Internet of Things (IoT) devices and wearables. The so-called wake-up receiver wakes up a device only when it needs to communicate and perform its function. It allows the device to stay dormant the rest of the time and reduce power use.


The technology is useful for applications that do not always need to be transmitting data, like IoT devices that let consumers instantly order household items they are about to run out of, or wearable health monitors that take readings a handful of times a day.
