This E-Team developed Powercast, technology that powers small electronic devices by electricity broadcast through the air. A transmitter plugs into the wall, and a dime-size receiver can be embedded into any low-voltage device. The receiver turns radio waves into DC electricity, recharging the device's battery at a distance of up to three feet.
Markets abound for Powercast, ranging from cell phones to lighting to pacemakers and defibrillators. The team has partnered with electronics giant Philips, and recently won Best of Show at the 2007 Consumer Electronics Exposition in Las Vegas.
