Improving battery life by harvesting ambient energy
Yesterday, the New York Times featured an article discussing the ongoing research towards alternate methods of powering mobile devices (http://goo.gl/78N9tN
). Among the methods mentioned was the design of a system that enables devices to communicate using ambient radio frequency (RF) energy as the only source of power.
In the paper Ambient Backscatter: Wireless Communication Out of Thin Air
, recipient of Best Paper at SIGCOMM 2013 (http://goo.gl/FsOmpa
), University of Washington PhD student Vincent Liu and co-authors demonstrate a new communication system that backscatters ambient RF signals, allowing data transmission without drawing on the device’s battery.
This work builds upon the Wireless Ambient Radio Power (WARP)
research by two of the paper’s co-authors, PhD student +Aaron Parks
and Associate Professor +Joshua R Smith
, on development of remote sensor units powered by the ambient RF signals. Read more about WARP, recipient of the Google Faculty Research Award (http://goo.gl/6XFmi
) in 2011 and 2012, in our previous post at http://goo.gl/eE4yWI
