Abstract: Needle-type hydrophones for the calibration of medical ultrasonic transducers have been fabricated using lead zirconate titanate (PZT)/poly(vinylidene fluoride-trifluoroethylene) (PZT/P(VDF-TrFE)) 0-3 nanocomposite films. The 0-3 nanocomposite film has been prepared by incorporating nanosized PZT powder (derived from a sol-gel process) in a P(VDF-TrFE) matrix. Since the piezoelectric coefficients of PZT and P(VDF-TrFE) have opposite signs, the PZT and P(VDF-TrFE) phases in the nanocomposites have been poled in opposite directions in order to give enhanced piezoelectric activity. A nanocomposite hydrophone with 0.2 volume fraction of PZT has been characterized and found to be more sensitive than a P(VDF-TrFE) hydrophone of similar structure.
