The Wave of the Future: Wireless Charging via Ultrasound?

uBeam, a wireless charging platform that uses ultrasound to send electricity to devices through the air.


That’s right. Ultrasound.

uBeam founder, Meredith Perry, has created technology that can take electricity and convert it into sound and then send that sound through the air over ultrasound. A device then catches the sound which then converts it back to electricity.

“This is the only wireless power system that allows you to be on your phone and moving around a room freely while you’re device is charging,” Ms. Perry said in an interview. “It allows for a Wi-Fi-like experience of charging; with everything else you have to be in close range of a transmitter.”

Pretty crazy, right?
