IoT inspires new components for energy, wireless

Stephen Lawson | July 25, 2014
The expected boom in demand for small, often isolated devices in the Internet of Things is driving developers to craft new types of components.

"For IoT, the criteria are different," Edgar said. "It's small amounts of data, occasionally." For example, a temperature sensor in a home might take readings every 15 minutes and send a few hundred bytes. Whisper might also be used in industrial sensors, wearable devices or smart electrical grids, he said.

Whisper is designed for use in chips built with the MIPS architecture, which Imagination acquired in 2012. It can be implemented in a MIPS chip specifically for communications or built into a single chip that also handles application processing and other tasks, Edgar said. The Whisper is scheduled to ship in a series of different versions starting in the fourth quarter.

It's hard to say whether the Omron-Holst vibration-harvesting design could power a device using Imagination's new architecture, because there are many ways to measure energy, Edgar said. But the voltages it could generate are within the right range.
