An acoustic energy harvester using piezoelectric backplate has been studied numerically using COMSOL Multiphysics 4.3. There are many research activities focusing on harvesting various environmental energies. However, acoustic energy harvesting has seldom been studied. In this study, a Helmholtz Res...
