uBeam: Wireless Electricity

The New York Times' Nick Bilton brings to attention the wireless charging platforms created by uBeam. The system works by using ultrasound to send electricity to a device through the air.

When Meredith Perry, 25, started studying astrobiology at the University of Pennsylvania, her career goal was to eventually find life on other planets. Instead, Ms. Perry accidentally stumbled upon something even more exciting: the ability to charge portable electronics, like cellphones and laptops, wirelessly using ultrasound.

To do this, Ms. Perry created a technology that can take electricity, convert it into sound and send that audio through the air over ultrasound. Then a receiver attached to a portable electronic device catches the sound and converts it back into electricity.

The technology makes it possible for a device to move freely around a room, in a pocket or purse, while constantly charging.
