Abstract

An analytical model for doubly clamped piezoelectric energy harvesters with segmented electrodes, considering the effect of strain nodes formation and charges cancellation issues, is presented. The single-mode power and voltage outputs of each of the lead zirconate titanate segments are obtained and are connected in series across a resistive load for the total outputs. The analytical solutions are found to closely agree with the Finite Element Method (FEM) simulation results obtained from COMSOL Multiphysics.
