Performance Evaluation of Novel Piezoelectric Cantilever Beam Structure for Energy Harvesting

This study proposes an elastic compact Piezoelectric energy harvester (PEH) in multiple configurations, including a single cantilever beam, beam with hole, two beams hole contributing towards wider operating bandwidth. The are designed structural forms and section shapes, symmetrical uniform rectangle frames. Natural frequencies, vibration modes, output voltages of PEH estimated using Finite element software, the frame acting as rigid body plate deformed structure. A rectangular surrounded by is attached to platform customized fixture simulation software. design meets requirements natural frequency high voltage low-frequency band. structure simulated variety piezoelectric materials, primarily PZT4 PZT5H, barium titanate, lithium niobate, zinc oxide, polyvinylidene difluoride (PVDF) finite method. In configuration holes, exhibited maximum 32.832 V for Zinc oxide compared other materials. So, it can be concluded that insertion variation geometry along plays vital role achieving large from vibrations PEH. HIGHLIGHTS approach was used develop simulate cantilever-based harvesting Multiple designs, plate, plates different materials frame, insertion, modification all play important roles generating substantial presents Eigen analysis structures GRAPHICAL ABSTRACT
