Modeling and Analysis of Ultrasonic Transducer with Single Crystal Piezoelectric Material
압전단결정을 이용한 초음파 탐촉자 모델링 및 해석
Abstract
In this research, modeling and analysis of an ultrasonic transducer composed of single crystal piezoelectric material(PMN-28PT) are conducted with FEM in reference with that composed of piezoelectric ceramic(PZT-4). Acoustic performances of the ultrasonic transducer are compared with magnitude, phase of impedance and trasmitting voltage response according to the type of piezoelectric materials.
