摘要：

In this paper, a percussive piezoelectric energy harvester device is proposed, which can better obtain the vibration energy in the low frequency. Through the construction of the experimental prototype and the experimental test, the results show that the output power is affected by the acceleration and the thickness of the percussive beam. When the free end mass of the piezoelectric beam is 3 g and the excitation frequency is 12.8 Hz, the maximum output power of the energy harvester is 316.8 mu W. It is 2.3 times of the maximum output power of the energy harvester without mass.
