摘要：

Harvesting electric energy from mechanical vibration using a mechanically excited piezoelectric circular membrane array is presented in this paper. The piezoelectric circular diaphragm array is consisted of four plates with parallel connection, and the electrical characteristics of the array are examined under dynamic conditions. With an optimal load resistor of 11 k Omega, an output power of 27 mW was generated at 150 Hz under a pre-stress of 0.8 N force and a vibration acceleration of 9.8 m/s(2). The results show that using a parallel array can increase significantly the output of energy compared with the use of a single plate.
