Design and Performance Analysis of Different Structures for Low-Frequency Piezoelectric Energy Harv piezoelectric energy harvester (PEH) applications. For proper selection of the material, a comparison is made among different piezoelectric materials and it is observed that for capturing low-frequency range Lead Zirconate Titanate (PZT-5H) is a better choice. All cantilever structures discussed in
