Title: STUDY OF THE ACOUSTIC PIEZO SENSOR MATERIAL INFLUENCE ON THE SENSOR’S CHARACTERISTICS
Keywords: acoustic sensor, COMSOL modelling, material properties

Abstract: In this paper we have studied the behaviour of piezoacoustic transducer that converts the electrical charges produced by the piezoelectric material. The study examines the change in the pressure level on the surface of the membrane at different frequencies from 10 kHz to 60 kHz, which partially overlaps with the ultrasonic range. Three different materials are used and examined for the 2D model in COMSOL: BaTIO3 ceramics, lead zirconate titanate and piezoelectric polymers (PVDF).
