Plucked Piezoelectric Bimorphs for Energy Harvesting

Chapter

Abstract

In this chapter, the plucking technique of frequency up-conversion is introduced, modelled and applied to energy harvesting. The aim of the technique is to bridge the gap between the high-frequency response of piezoelectric energy harvesters and the low-frequency input that is most often available from the ambient environment. After covering the general principle of plucking excitation, the plucking action is modelled analytically as well as with finite element analysis. Finally, the application of plucked piezoelectric bimorphs to a wearable knee-joint harvester (the pizzicato energy harvester) is discussed in some depth to show the potential of the plucking technique of frequency up-conversion.
