| Research Abstract |
Copolymer of vinylidene fluoride and trifluoroethylene [P(VDF/TrFE)] has the largest coupling factor (kt=0.3) among piezoelectric polymers.Furthermore, it is possible to transmit and receive the ultrasonic waves at MHz range,because of that low acoustic impedance of P(VDF/TrFE) transducer. In this study, Acousticimaging of the substance inside was tried using P(VDF/TrFE) transducers made by asolution casting method for use in the MHz range in air. As the results, acoustic imagingusing the air coupled P(VDF/TrFE) transduces at 2.5 MHz had succeeded to display a chipof IC (ROCKWELL/11229-12).
