Performance enhancement of ultrasonic transducer made of textured PNN-PZT ceramic

In this paper, 0.36Pb(Ni1/3Nb2/3)O-3-0.24PbZrO(3)-0.40PbTiO(3)(PNN-PZT) ceramic was prepared, and texture engineering was performed on this PNN-PZT ceramic to improve its electromechanical properties and temperature stability. Single element ultrasonic transducers were prepared using PNN-PZT, PNN-PZT textured ceramics, and their performance were evaluated and compared using a PZT-5H ceramic based transducer as the benchmark. It is shown that the sensitivity and bandwidth of the PNN-PZT textured ceramic-based transducer are much superior to regular PNN-PZT ceramic and PZT-5H ceramic based transducers.
