New chip that wakes up device only when it needs

NEW YORK: Engineers at the University of California San Diego have developed a new power-saving chip that 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.
