SOZU MONITORING SYSTEM HARVESTS ACTIVITY ENERGY RUNS WITHOUT BATTERIES

SOZU MONITORING SYSTEM HARVESTS ACTIVITY ENERGY & RUNS WITHOUT BATTERIES

A team of Researchers at Carnegie Mellon University’s Future Interfaces Group have developed self-powered radio tags called Sozu, which enables building-scale activity sensing, without the need for line-of-sight and at a very low cost. They claim a 99 percent detection rate and “almost no false positives.” The team of researchers includes Yang Zhang, Yasha Iravantchi, Haojian Jin, Swarun Kumar, and Chris Harrison. Sozu
