Project Sozu: Self-Powered Radio Tags for Building-Scale Activity Sensing

Sozu is a low-cost sensing system that can detect a wide range of events wirelessly, through walls and without line of sight, at whole-building scale. Instead of using batteries, Sozu tags convert energy from activities that they sense into RF broadcasts, acting like miniature self-powered radio stations.
