C6.1 - Topology Optimization of a Piezoelectric Energy Harvester

Fabian Wein, Elias Weller, Thorsten Albach, Alexander Sutor & Reinhard Lerch
We use a thin piezoelectric layer attached to a mechanical plate to harvest mechanical energy as available at the vibrating skin of machinery. By modifying the material distribution of the piezoelectric layer the resonance frequency of the energy harvester is adjusted to maximize the objective function. In this paper the electric energy and the electric potential is maximized. This topology optimization problem is performed by a variant of the SIMP (Solid Isotropic Material with Penalization)...
