Piezoelectric Coefficient and Permittivity Changes in Piezoelectric Material ZnO as Functions of Applied Electric Field

The piezoelectric coefficient and permittivity of a piezoelectric material depend on the crystal structure which can be modified by an external electrical field. In this research, we aim to find out a relationship between external electrical field and the piezoelectric and permittivity properties of ZnO. The numerical analysis, finite element analysis, and experimental measurements are to be addressed in this paper. The result of this work can be a good source for the study of piezoelectric material.
