Study on Power Generation Performance of Quad-Stable Wake Galloping Energy Harvester

Abstract

Advances in MEMS technology have greatly reduced the power consumption of the sensor, and it is possible to power it with environmental energy. In this paper, a quad-stable cantilever piezoelectric wake-galloping energy harvester is proposed by introducing nonlinear quad-stable vibration into the system. The mechanical model of the harvester system is established, and governing equations are obtained. The effect laws of the potential well depth on the harvesting performance of the quad-stable wake-galloping energy harvester are studied. The above research results can provide some reference for the study of wake-galloping energy harvesters.
