Resumo: Based on the necessity for cleaner and renewable energy and the growing global demand, energy harvesting stands out increasingly in this scenario. This technique is notable for the possibility of converting some types of energy that are generally neglected into electrical energy that can be used to power low-consumption electronic devices. In this context, piezoelectric materials demonstrate excellent applicability due to their ability to convert kinetic energy into electrical energy. Although these concepts and principles of conversion have been known for a long time, their use has increasingly grown in recent years. Thus, the present work objectively focuses on the electrical characterization of a thin-film piezoelectric sensor of Polyvinylidene Fluoride (PVDF) and a computational modeling of its behavior in LTSpice® software as a preliminary step of a study aimed at the development of a piezoelectric energy harvester (PEH). Consequently, this work allows for identifying and analyzing the intrinsic needs of the project, contributing to the optimization of the PEH performance.
