Piezoelectric Effect in Composite Polyurethane–Ferroelectric Ceramics

Year: 1999

Type: article

Abstract: Flexible and free-standing films of piezoelectric composites made up of lead zirconate titanate (PZT) ceramic powder dispersed in a castor oil-based polyurethane (PU) matrix were obtained by spin coating and characterised as materials for sensor applications. The piezoelectric coefficients d31 and d33 were measured with the usual technique. The piezoelectric charge constant d33 yields values up to ≤ 24 pC/N, even at lower PZT content (33 vol%). Some desirable properties like piezoelectricity, flexibility and good mechanical resistance show this new material to be a good alternative for use as sensors and actuators.
