From the last few decades, the piezoelectric materials are playing a vital role in the field of energy harvesting because of their capability to convert mechanical energy from the surroundings into useful electrical energy. In this research, the performance of the piezoelectric energy harvester (PEH) in cantilever configuration with varying length and width of the patch as compared to the beam was analyzed. Moreover, the induced voltage and power harvested by the designed PEH are analyzed for the various configurations of piezoelectric patch (PZTp). The effect of length and width of the PZTp and beam is predicted for the energy harvesting phenomenon. The effect of different piezoelectric materials [i.e. Lead zirconate titanate (PZT-5A) and Barium titanate (BaTiO₃)] bonded to different non-piezoelectric materials (i.e. Aluminum (Al) and fiberglass) is studied analytically. An analytical model is developed for three …
