Abstract

Polymer ultrasonic transducers for 1.5-10 MHz transverse waves were first developed using thickness shear resonators composed of multi-layered lamellar crystalline films or single crystalline films of P(VDF/TrFE), and their performance was evaluated. These transducers can transmit and receive pure shear waves with high efficiency. The S/N ratio of these transducers is higher than that of conventional PZT shear mode transducers. The developed transducers are usable for practical applications such as NDE and physical acoustics after some trivial improvements
