Abstract

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.
