Abstract
A three-dimensional finite element model is developed to completely characterize the electromechanical response of a general piezoelectric material with spherical or cylindrical porosity, respectively, with zero-dimensional (3-0) or one-dimensional (3-1) connectivity and to obtain a quantitative assessment of the effects of porosity connectivity on the effective performance characteristics of porous piezoelectric materials. By considering materials with different crystal symmetries, it is demonstrated that piezoelectric materials designed with spherical porosity (with 3-0 connectivity) exhibit enhanced hydrostatic figure of merit and are more suitable for hydrophone applications, as compared to materials engineered with cylindrical porosity (with 3-1 connectivity).
