A composite of PZT Lead Zirconate Titanate and a compliant polymer having 1-3-0 connectivity is described. A polymer self-connected in all three mutually perpendicular directions with a void in the center has an array of parallel PZT rod elements embedded therein and extending through the void. The void isolates a region of the PZT rods from the polymer. The axes of the PZT rods are along the direction of the poling electric field. Such an arrangement significantly enhances the hydrostatic piezoelectric charge and voltage coefficients d sub h and g sub h. Keywords Piezoelectric materials Hydrophones Hydrostatic pressure.
