Polymer/ceramic composite piezoelectric materials with 0-3 connectivity have been produced by dispersing ceramic powder of calcium modified lead titanate into the matrix of three different host polymers. The piezoelectric coefficient and the dielectric constant as well as the electromechanical coupling factor of the composite films are determined. Two piezoelectric transducers have been constructed using these films. The composite piezoelectric sensors were used to monitor strain and acoustic emission levels during tensile testing.
