Comparison between four piezoelectric energy harvesting circuits

Jinhao Qiu, Hao Jiang, Hongli Ji, Kongjun ZHU

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 2,   Pages 153-159 doi: 10.1007/s11465-009-0031-z

Abstract: This paper investigates and compares the efficiencies of four different interfaces for vibration-based energy harvesting systems. Among those four circuits, two circuits adopt the synchronous switching technique, in which the circuit is switched synchronously with the vibration. In this study, a simple source-less trigger circuit used to control the synchronized switch is proposed and two interface circuits of energy harvesting systems are designed based on the trigger circuit. To validate the effectiveness of the proposed circuits, an experimental system was established and the power harvested by those circuits from a vibration beam was measured. Experimental results show that the two new circuits can increase the harvested power by factors 2.6 and 7, respectively, without consuming extra power in the circuits.
