Abstract

Due to developments in additive manufacturing, the production of Piezoelectric materials with complex geometries is becoming viable and enabling the manufacturing of thicker Harvesters. Therefore, in this study a Piezoelectric harvesting device is modelled as a bimorph cantilever beam with a series connection and an intermediate metallic substrate using the plane strain hypothesis. On the other hand, the thickness of the Harvester’ s Piezoelectric material is structurally optimized using a discrete topology optimization method. Moreover, different optimization parameters are varied to investigate the algorithm’ s convergence. The results of the optimization are presented and analyzed to examine the influence of the Harvester's geometry and its different substrate materials on the Harvester’ s energy conversion efficiency.
