Researchers led by Alanson Sample, associate lab director and leader of Disney Research’s Wireless Systems group, devised an ultra-low-power system of sensors that transmit data to a central receiver by reflecting the ambient radio waves from commercial broadcasting systems that already bathe most office environments.

“Our idea is to reuse all the radio signals that are around us as a medium for transmitting data, much like sending ripples across a pond,” Sample said… More at EurekAlert!

This is the kind of thinking that will be the innovation we want to see in future devices.
