Abstract

The piezoelectric properties of several different composites with 0-3 connectivity are reviewed. In these composites a piezoelectric ceramic powder such as PbZr_1-xTi_x0₃ (PZT), PbTi03 or Pb_l-xBi_x-Ti_l-TFex0₃ is used as a filler in a polymer matrix. The values of hydrostatic voltage coefficient ih of these composites are higher than the corresponding properties of single phase materials. Composites with PbTi03 or (Pb.Bi)(Ti.Fe)O₃ as fillers have higher piezoelectric voltage coefficients than PZTpolymer composites because of the greater anisotropy and lower dielectric constants of these systems. By adding a small amount of carbon to the piezoelectric composite, poling can be carried out at much lower voltages and shorter poling times, making it possible to mass produce the composites. Fabrication of 0-3 composites is a relatively simple process which can be adapted to the production of piezoelectric fabrics, piezoelectric cables, and piezoelectric paint.
