“…Computational modeling provides a powerful tool to gain insight into the electromechanical behaviors and guide the design of PVDFbased harvesters. Various authors conducted finite element studies on the displacement of PVDF cantilever and actuator beams against the clamped end, [46][47][48][49][50][51][52] but there are scarcely literatures reported on the displacement along the arc length of PVDF arrays or nanofibers. [53][54][55][56] However, several works reported the distributions of piezoelectric potential under mechanical loadings.…”

Poly(vinylidene fluoride) (PVDF) is a promising piezoelectric and pyroelectric material for energy harvesting applications. This paper investigates the electrical outputs of PVDF microarrays using both simulation studies and theoretical calculations. The finite element method in COMSOL Multiphysics® is utilized to model PVDF microarrays and simulate their responses under mechanical loading and temperature changes. Theoretical calculations are also performed to estimate the piezoelectric and pyroelectric voltage outputs using established mathematical formulas. A series of PVDF microarrays are modeled in two dimensions with defined geometry, materials, boundary conditions, and parametric sweeps of wind speed and temperature. The simulation results for electrical outputs show good agreement with the theoretical calculations, demonstrating the validity of both approaches. The maximum voltage outputs are on the order of 10−3 V for the range of wind speeds from 6.5 to 11 m/s and temperatures from 319.3 to 336.3 K. In addition, the mechanical and thermal sensitivities are quantified. This work provides a framework for design and optimization of PVDF‐based energy harvesters. The combined methodology enables characterization of the relationships between operational conditions, PVDF microarray properties, and electrical outputs.

“…In another study, a numerical model of a Glass Fiber Reinforced Polymer (GFRP) cantilever beam with the piezoelectric materials, PZT and PVDF was considered for energy harvesting and a comparison of PZT and PVDF materials was presented. 34 Lee et al 35 provided a shape optimization study for a cantilever type piezoelectric energy harvester by conducting numerical simulations. In this study, the cantilever harvester was subjected to vibration on the tip and PZT and PVDF layers were considered with different combinations of shapes.…”

Increasing energy consumption has led recent efforts towards energy harvesting technologies. Among them, piezoelectric energy harvesting with piezo-based sensors and energy harvesters have gained significant attention due to their applicability and efficacy for microscale power generation systems. Present study aims to investigate energy harvesting with piezoelectric materials from structural vibration propagating throughout the structure from vibration sources. For this purpose, a use case of a mechanical pump mounted on a steel foundation is chosen. A Finite Element (FE) model of the foundation of the pump with piezoelectric energy harvesters is developed and validated in an experimental setup. Measured frequency response functions (FRFs) show particularly good match with simulation results. Afterwards, a real measured acceleration data from the mechanical pump is applied. Simulations are performed and effectiveness of the piezoelectric energy harvester for two different locations are demonstrated. In this study, piezoceramic (PZT), PVDF polymer, ZnO film and a PMN-PT single crystal composite is considered as harvester material and the effectiveness of each piezoelectric material are compared.
