The performance characteristics we focus on are the hydrostatic charge coefficient , the hydrophone figure of merit , and the electromechanical coupling factor . 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 and , the optimal transversally isotopic matrix material has negative Poisson's ratio in certain directions. When we design for maximum , the optimal matrix microstructure is layered and simple to build. Copyright © Materials Research Society 1998 Sigmund O.
