Piezoelectric materials are widely used as an input transducer to harvest electrical energy. In this research, an optimized piezoelectric transducer (PZT-5H) has been designed for maximum efficiency. The transition system consists of an ideal mass, spring and damper. It has been modeled using MATLAB Simscape Toolbox™. Routh–Hurwitz criterion is applied to assess the stability of the transition system. The root-locus and step-response plots are generated for the stability analysis. Effects of varying stiffness, damping coefficient and thickness have been studied in designing of stack PZT-5H. The statistical analysis based on a Taguchi design of experiment and analysis of variance approaches is implemented to obtain the optimum output response from the energy harvester. Consequently, interval plots and a regression model are designed to establish an adequate relationship between the controllable …
