摘要：

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 win 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 mu W-rms scavenged by a miniature electromagnetic (EM) vibration energy harvester of volume approximate to 150mm(3) from a modest vibration level of 0.6ms(-2)
