Wire-Free Charging of Electronic Devices Within 15-Foot Radius

San Jose, CA-based company Energous Corporation is developing WattUp™, a wire-free charging technology for electronic devices that provides power at a distance, and recently held demonstrations during 2015 International CES. In this video, Energous CTO Michael Leabman demonstrates the technology. A WattUp transmitter, or power router, sends energy via a radio frequency (RF) signal to a user's WattUp-enabled electronic devices when requested. It delivers energy within a 15-foot radius of where they are installed, creating a 30-foot envelope of wire-free charging space. Each power router can charge up to 12 devices at the same time. WattUp receivers use multiple miniature antennas to harvest the micro energy beams sent from the transmitter. The whole wire-free charging system is software controlled. Using either a mobile app or cloud-based web portal, users can to identify which devices they want to receive power and when.

00:00:16 hi my name is Michael Liebman I'm the CTO and founder of energist corporation I'm here today to give a demonstration of our wire free energy router I have two devices I'm going to demonstrate charging I have a receiver cover on an iPhone I also have a universal receiver that we designed to charge into any any different device in this case we're showing another iPhone the last thing I

00:00:40 have here is our software management tool or app that allows us to select which devices we charge and when we charge those devices now our energy router you see today is on a tripod you can imagine it being on your desk at home on a bookshelf being in a coffee house wherever you would go you would charge your device I'm going to tell our software app to go ahead and

00:01:02 start charging the phone and what you'll see is the phone will start charging whether I'm five feet away or I move five ten feet away we're still charging the device it's completely mobile now if I go to fifteen feet away and you'll see we're still charging the first device I'm going to tell the software go ahead locate the second device once the transmitter finds the device and

00:01:26 authenticates it the device will start charging well there you have it wire free charging of multiple devices at up to 15 feet for more information visit us at energies calm you
