Radio Waves as Power Source

Radio Waves as Power Source

A Californian startup has built a wireless charging system that transmits electricity using high-frequency radio waves, specifically the millimeter wave (mmWave) variety that underpins burgeoning 5G cell networks in the US.

Guru has unveiled three prototype charging products it wants to develop in partnership with electronics manufacturers. The three prototypes include a desk charging system that can wirelessly charge pretty much any gadget within a few feet, a room-scale version the size of a ceiling tile that has significantly more range, and a roving Roomba-like robot that’s designed to move around a large space and charge small, smart home-style gadgets like cameras and IoT sensors.

The real innovation Guru claims it has pioneered is something the company calls Smart RF Lensing. It allows Guru to send multiple beams of energy to even tiny receivers, which is what allows the transmission devices to be shrunk down enough to fit on your desk or be mounted to a wall. It also allows Guru’s system to charge devices as small as cellphones and even smaller IoT and smart home devices.
