Electrical characterization and modelling of polyvinylidene fluoride thin film for application in piezoelectric energy harvesting

The search for clean and sustainable energy sources has increased dramatically in recent years. As a result, research into Energy Harvesting (EH) technology has become increasingly important. EH allows powering low-consumption electronic devices by converting types of energy that are commonly neglected into electrical energy. In this scenario, piezoelectric materials stand out due to their property of converting kinetic energy into electrical energy. Therefore, this article aims to focus on the electrical characterization of a Polyvinylidene Fluoride (PVDF) piezoelectric transducer and a computer modelling of its behavior using the LTspice® software, as well as its coupling to an EH power management chip (LTC3588-1), as the initial phase of a research project aimed at developing a piezoelectric energy harvester (PEH).
