Abstract: This paper presents the conversion of mechanical vibration into electrical energy using piezoelectric cantilever based energy harvester. By using Comsol Multiphysics 5.2 we constructed various geometries of the cantilever beam in order to compare displacement and voltage and hence calculate the generated power. The effect of these geometries is studied by applying stress or load on the cantilever beam. The H-Shaped cantilever generates a maximum power of 98.37µW at frequency of 65.32Hz, whereas the L-shaped cantilever, rectangular cantilever, rectangular cantilever with a rectangular hole generates less power 55.16µW, 2.85µW and 4.09µW respectively. This piezoelectric energy harvester can be used for powering sensors associated with internet of things (IoT).
