Experimental study on power generation performances of a novel piezoelectric energy harvester

AbstractIn 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.Keywords: Vibration energycantilever beampiezoelectricscavenge energy Additional informationFundingThis work was supported by the Shandong Provincial Natural Science Foundation (ZR2022ME053), National Natural Science Foundation of China (No. 51975303), Shandong Provincial Key Laboratory of Precision Manufacturing and Non-traditional Machining and The Youth Innovation Team Development Program of Shandong Provincial Higher Education Institutions (2022KJ234, 2022KJ235).
