A plenty of research has been conducted recently to increase the power output and broaden the working bandwidth of energy harvesters. We proposed a high-efficiency compressive-mode energy harvester using piezoelectric materials, which exhibited a superior power-generation capability and nonlinearity-induced wide bandwidth. This study aims to develop a comprehensive electromechanical model for the proposed energy harvester. Specifically, using the Hamilton principle and the Euler-Bernoulli beam theory, we first obtained the governing equations of the electromechanical system. The model was then discretized using a Galerkin expansion and solved numerically. We finally compared the simulation results with the experimental data tested from a fabricated prototype. The developed distributed-parameter model gives us a deep insight into the dynamic characteristics of the system that can help further enhance the performance.
