Abstract: Piezoelectric energy harvesting has garnered significant interest as a sustainable method for generating electrical power from mechanical vibrations. In this study, we compare the performance of three commonly used piezoelectric materials—Lead Zirconate Titanate (PZT), Aluminum Nitride (AlN), and Polyvinylidene Fluoride (PVDF)—for vibrational energy harvesting applications. Using computational simulations, we analyze the average harvested power, peak power, power density, and power-to-acceleration ratio for varying thicknesses of each material. Our results reveal distinct performance characteristics among the materials, with PZT exhibiting superior power output and efficiency compared to AlN and PVDF. AlN demonstrates moderate performance across the parameters studied, while PVDF exhibits comparatively lower power output and efficiency. These findings provide valuable insights for engineers and researchers in selecting the most suitable piezoelectric material for energy harvesting applications based on specific performance requirements and constraints.
