Abstract
This paper reports, for the first time, the implementation of a microsystem powered entirely from ambient vibrations. Sufficient electrical energy is harvested to power a radio-frequency (RF) linked accelerometer based microsystem. The microsystem is energy aware and will adjust the measurement/transmit duty cycle according to the available energy; this is typically every 50 seconds during normal operation. The system is fully powered from 45 muWrms scavenged by a miniature electromagnetic (EM) vibration energy harvester of volume ; level of 0.6ms-2.Keywords
