In this article, a new type of piezoelectric energy harvester device is proposed, which has good output performance and can scavenge a large amount of vibration energy at low frequency. By setting up the experimental platform and testing, the results show that the external resistance, the mass of the cantilever end, the excitation acceleration and the magnet distance have an impact on the device. When the mass of the end of the cantilever beam is 15 g and the acceleration is 0.5 g, the output power of the device is 5.2 mW, and the output performance is good. [ABSTRACT FROM AUTHOR]

Aiming at the problem that the energy harvestaing efficiency of traditional piezoelectric energy harvester is not high enough. A zigzag-shaped beam vibration energy harvester was proposed, which has excellent output performance. The effects of external resistance, mass weight, excitation acceleration and mass placement position on the output performance of the harvester were researched using the experimental platform. The results show that under the condition of 100 kΩ, when the mass weight is 9 g and the acceleration is 0.3 g, the maximum output voltage and power are 19.98 V and 3.992 mW respectively.
