Abstract

Abstract: In this article, a nonlinear piezoelectric harvester coupled with a standard rectifying circuit is developed. Contrary to traditional Duffing-type magnetic harvester mechanism, the nonlinear effect in the system is induced by a dynamic tipmass with embedded magnet. Further, dynamic equation of the system is derived and subsequently, its equivalent circuit model is devised to evaluate its performance with a conventional harvester. Simulation and experimental results exhibit that the nonlinear effect due to the force coupling has a profound effect on peak output power and operational bandwidth of the harvester as compared to linear system with DC interface circuit.
