Comparative simulation study of a cylindrical piezoelectric pressure sensor using COMSOL Multiphysics
In this work, a two-dimensional (2D) axisymmetric model of a cylindrical piezoelectric pressure sensor was established to exploit its rotational symmetry. Five piezoelectric materials, i.e., PZT-5H, PZT-5A, PVDF, BaTiO3, and AlN, were evaluated to compare their piezoelectric response under internal pressures ranging fr...
