Experimental study on energy-generation performance of a zigzag-shaped beam piezoelectric energy harvester
FERROELECTRICS(2023)
Abstract
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 k omega, 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.
