Abstract

The paper presents a two-phase FEM-based topology optimization for piezoelectric energy harvesting devices. The goal of this research is to improve energy conversion efficiency of the piezoelectric cantilevered plates as an energy harvesting device based on the piezoelectric effect when applied to external loads. Owing to the friability of piezoelectric material, the piezoelectric energy harvesting devices can contain both piezoelectric material and elastic material. Therefore, an alternative way to express the piezoelectric material property interpolation for two-phase materials structure has been proposed. With this method, the structure composed of two materials, including elastic material and piezoelectric material, is regarded as the design variable under the topology optimization formulation. It seems to be a more reasonable solution for the topology optimization of piezoelectric composite materials. The method of moving asymptotes (MMA) is used to update the design variables. The energy conversion efficiency is compared using a developed FEM-based optimization code to verify the performance of the proposed method. Some numerical examples are presented and investigated to verify the availability of the proposed method.
