Abstract
This study provides the first comprehensive experimental validation of isolated high-energy orbits and broken bands in nonlinear piezoelectric energy harvesters (NPEHs), phenomena previously predicted only through numerical simulations. These high-energy orbits, emerging in bistable configurations, significantly enhance energy harvesting efficiency. The broken band phenomenon, observed in both monostable and bistable systems, offers practical guidance for optimizing resistance selection. Our experimental results confirm the reliability of our previously proposed analysis framework and deepen the understanding of NPEH dynamics. These findings lay a foundation for developing more efficient energy harvesting strategies and have significant implications for practical applications.
