Abstract

PZT/P(VDF-TrFE) 1-3 composites were fabricated by embedding pre-sintered PZT rods in a pre-poled copolymer matrix. The rods were then poled using an electric field much lower than the coercive field of the copolymer. The electromechanical coupling factor kt, and the resonance characteristics of the composites were measured. The resonance characteristics of the composites were found to be dominated by the individual PZT rods. Poling of the copolymer matrix results in broadening of the main resonance peak. For transducer applications, it is advisable to pole the copolymer and the PZT rods in the same direction as this gives a higher ktvalue.
