Abstract

The use of Piezoelectric Energy Harvesters (PEHs) offers a promising solution for emerging low-power electronics and IoT devices. This study investigates the performance of a nonlinear PEH model, which incorporates two permanent magnets in a bimorph configuration. Both analytical methods and COMSOL Multiphysics simulations are employed. The results reveal two distinct peaks, with the maximum voltage and power output reaching 7.83 V and 2.47 mW, respectively, at 74 Hz. It is observed that increasing the distance between the magnets decreases the output results. Although the voltage output closely matches experimental findings, there are slight differences in parameters. A comparison highlights the potential of the nonlinear model to improve output while also acknowledging its inherent complexity. Future research directions include optimizing magnet configurations, integrating with energy management systems, and exploring advanced materials.
