DESCRIPTION:The energy efficiency of computing has improved by a factor of
  more than a trillion since the electronic computer was invented.  This as
 tounding energy efficiency scaling is creating the opportunity for battery
 -free sensing and computing systems that are powered by radio waves and ot
 her ambient energy sources.  Such devices can be implanted inside the body
 \, permanently built into structures\, or deployed at scales where batteri
 es and wires are infeasible.  I will describe my group’s work aiming to 
 enable battery-free\, perpetual sensing and computing systems.  I will des
 cribe our work on RF energy harvesting\, wireless power transfer\, and amb
 ient backscatter communication\, as well as sensor systems built using the
 se building blocks\, including a battery-free mobile phone and camera syst
 ems.  I will also describe computer science research challenges that can h
 elp make perpetual computing systems a reality.
