Abstract
This study uses computer tomography (CT) and a finite element method (FEM) criterion to establish a digital twin (DT) model for Polyvinylidene fluoride (PVDF) film. The CT provides sliced images of the PVDF film with 50 μm, and we have developed a standard procedure to rebuild the stereo and interior model of the PVDF film. We also use a d33 meter to measure the piezoelectric effect of the PVDF film and utilize the value in the FEM model. The primary material of the piezoelectric film is polyvinylidene fluoride, which has a unique dielectric effect, piezoelectric effect, and pyroelectric effect. In this study, computer tomography was used to establish the microstructure model of the film, and ANSYS software was used to establish the microstructure model. The primary purpose of simulating the piezoelectric effect of the self-made piezoelectric film is to compare the small holes contained in the film structure and the forward and reverse piezoelectric responses of different structures in the same environment. This study has established three different DT-FEM models and simulated the piezoelectric effect of the thin film. The DT-FEM model contributes to the emerging technology of material science and helps scientists to investigate the piezoelectric effect at the micro- and macro-scale.
