Abstract

We use a topology optimization method to design 1-3 piezocomposites with optimal performance characteristics for hydrophone applications. The performance characteristics we focus on are the hydrostatic charge coefficient d^(*)_h, the hydrophone figure of merit d^(*)_hg^(*)_h, and the electromechanical coupling factor k^(*)_h. The piezocomposite consists of piezoelectric rods embedded in an optimal polymer matrix. We use the topology optimization method to design the optimal (porous) matrix microstructure. When we design for maximum d^(*)_h and d^(*)_hg^(*)_h, the optimal transversally isotopic matrix material has negative Poisson's ratio in certain directions. When we design for maximum k^(*)_h, the optimal matrix microstructure is layered and simple to build.
