A Pb(Zr, Ti)O3+0.5 Nb2O5 ceramic composite transducer exhibiting 3–3 connectivity was prepared by conventional powder methods. The dielectric, elastic and piezoelectric properties were measured. It exhibits a large piezoelectric voltage output coefficient (g-constant) of 130×10-3 V·m/N. Utilizing the new material, hydrophone sensitivity was increased to nearly four times that of normal Pb(Zr, Ti)O3 ceramics.
