Abstract

This paper presented an equivalent circuit simulation model of the cantilevered piezoelectric bimorph energy harvester for predicting the electrical power output of the energy harvester. The alternating voltage in the equivalent circuit model is identified from FE transducer model and the parameters of the resistance, capacitance and inductance in the equivalent circuit model are identified from FE actuator model. To valid the equivalent circuit simulation model, the power output values are compared with those obtained from the coupled piezoelectric-circuit finite element analysis. The results demonstrate the accuracy of the equivalent circuit simulation model.
