Abstract

This paper reports a wireless sensing device which is completely powered by inertial motion. Self-synchronous switching is applied to the device using switching diodes and reed switches, which allows the system to function in response to its moving proof mass. By combining piezoelectric energy harvesting and radio frequency (RF) transmission, a fully functional piezoelectric system is achieved, for the first time, allowing instantaneous wireless monitoring of signals from a passive sensor using frequency modulation (FM).
