Abstract

Flexible piezoelectric composites made from PZT and polymer with 0-0-3 connectivity were fabricated using several types of Eccogel polymer. The conductivity of the composite is controlled by adding small amounts of a semiconductor filler such as carbon, germanium or silicon. By controlling conductivity, poling can be carried out very rapidly at low voltages, resulting in properties comparable to composites prepared without a conductive phase. For composites optimized for hydrophone performance, the hydrostatic voltage coefficient g_h and hydrostatic figure of merit g_hd_h are an order of magnitude larger than those of single phase PZT.
