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?
