Interface Circuits for Piezoelectric Polyvinylidene Fluoride (PVDF) Films

This work explores the modeling of polyvinylidene fluoride (PVDF) films based on their physical characteristics. Additionally, it highlights the performance of various circuit interfaces used with PVDF films through both simulation and hardware implementation. Simulation results indicate that ideal specifications are met; however, in practical applications, environmental factors must be considered as they affect the electrical characteristics of PVDF films and, consequently, the performance of the entire circuitry.
