Abstract

Modelling of piezoelectric energy harvesting systems from vibration point of view is of interest of many researchers and plays an important role in the estimation of power output for these systems. This paper deals with the dilemma of damping modelling in piezoelectric harvesters as in most of modelling techniques only the viscous damping is considered. A discussion is firstly presented about the effect of damping modelling on the power output. Then a modelling approach for different damping mechanisms is presented by which energy dissipation in the piezoelectric harvester can accurately be modelled. Finally, based on this damping model, an analytical model is derived for power output estimation of piezoelectric energy harvesters.
