This research proposes the development of an energy harvesting system applied to sports shoe insoles, which uses human footsteps for energy generation. The concepts of energy harvesting and the phenomenon of piezoelectricity were used to manufacture a prototype consisting of a system with eleven piezoelectric sensors and a 3D printed insole made from PLA material. The prototype was tested using simulated footsteps, thus generating up to 1 V when an LED diode turned on. However, the energy generated was not enough to charge a low-power storage unit.

The subject of this project is the study of the technical feasibility of developing a piezoelectric energy harvester system with application in sports shoe insoles. The objective is to propose a system for capturing the energy generated from the footsteps while walking, for the charging of low-power devices. The first chapter presents the problem that was detailed with the introduction, the problem statement, the general and specific objectives, the hypothesis to be validated at the end of the project, and the technical, inventive and environmental sustainability justifications. The second chapter deals with the theoretical framework of the research. Scientific articles and thesis were reviewed to elaborate the referential framework, and key concepts were defined as part of the conceptual framework and the glossary of terms. The third chapter exposes the engineering of the project. Exist...
