Simulation of an Ultrasonic Transducer for Medical Applications Using the Finite Element Method

This paper presents the simulation of a PIC255 commercial piezoelectric ceramic which was used in the design of an 8 MHz ultrasonic transducer, as a novelty a biocompatible material known as rexolite was incorporated as acoustic matching. The FEM (Finite element method) was used in the simulation. This work shows that it is feasible to predict the response of the ceramic in each one of the stages generating with this a significant saving in time and human resources. Frequency responses are presented in addition to the stress and strain responses of the ceramic.
