Perforated PZT-polymer composites with 3–1 con- nectivity patterns have been fabricated by drilling square holes perpendicular to the poling direction in prepoled PZT blocks and filling the holes with epoxy polymer. The influence of the separation between the holes on the dielectric and piezoelectric properties of the composite was studied. The finite element method has been used to calculate the stress distributions in this composite. The hydrostatic dh and gh coefficients have been calculated by summing the individual element polarization. The calculated values are compared with experimental results.
