Consideration of macrosymmetry and interphase connectivity has been used to explore possible macrostructures of interest as piezoelectric composites. Based on these design considerations, ceramic polymer composites have been fabricated with 3-3, 3-1, and 1-3 phase connectivity. In general these composites yield a lower permittivity, higher hydrostatic charge coefficient (d//h) and voltage coefficient (g//h), and in some cases increased thickness coupling coefficient (k//t). These composites can be used to construct hydrophones, broad band filters, and deformable mirror base. The composites can be made flexible and conformal using an elastomer as the second phase.
