This paper presents a piezoelectric energy harvesting skin (EHS) design using topology optimization. EHS was motivated to embody a power-generating skin structure by attaching thin piezoelectric patches onto a vibrating skin for the purpose of self-sustainable health monitoring with wireless sensors. In this paper the hybrid cellular automata (HCA) algorithm is involved to optimize piezoelectric material distribution on a harmonically vibrating skin structure. Valid computational (finite element) models for vibrating structure are constructed, and the optimal piezoelectric material distribution is found on a surface of the structure. The piezoelectric material is modeled with penalization, and the optimal density and poling direction is found per each piezoelectric finite element using HCA algorithm. HCA algorithm demonstrated its ability to find the optimal design for piezoelectric material to yield maximum power output.
