Investigation on the influence of Lead Zirconate Titanate piezo material on different diaphragm materials in the mechanical deformation process

This paper focuses on the effect of Lead Zirconate Titanate (PZT-5H) piezoelectric material on different diaphragm materials to investigate the mechanical deformation of piezo and diaphragm materials. This model is based on the application of piezoelectric devices for its actuator function by using the COMSOL Multiphysics simulation software. The fundamental theory of piezoelectricity is used to describe the deformation in which applied potential voltage is converted into mechanical deformation. For the electric potential of 10 V, 15 V and 20 V, the distribution of Von Mises stress, minimum & maximum deformation in piezo material and different diaphragm materials has been calculated. Thus the outcome of this technical paper may provide a better understanding of behaviour of different diaphragm materials for piezoelectric applications.
