What is Abdelkefi Energy Harvester Using Piezoelectric Cantilever Beams Undergoing Coupled Bending Torsion Vibrations about?

This document presents a novel piezoelectric energy harvester using unimorph cantilever beams that undergo coupled bending-torsion vibrations. The design incorporates asymmetric tip masses to enhance energy conversion efficiency, achieving a 30% increase in harvested power compared to traditional bending-only designs. A distributed-parameter model is developed to analyze the system dynamics and optimize geometric properties for improved energy harvesting performance.
