Um estudo preliminar da piezoeletricidade como fonte renovável de energia aplicada aos pavimentos do Colégio Militar de Fortaleza

Abstract

The growing demand for electricity in today's society makes it a universal theme for economic, social, and environmental development. Thus, there is a need for alternatives for the production and generation of energy that make it possible to reduce environmental damage and supply the system. Piezoelectric energy represents an excellent clean energy alternative as it does not depend on climate or large areas for its application. The study presented here aims to investigate the potential and feasibility of piezoelectric energy as a clean energy alternative for use in self-sustainable projects of pavements. To this end, the characteristics and properties of piezoelectric materials were addressed, the benefits of using this type of energy were identified, and the different spaces where piezoelectricity can be used, in addition to its use at the Colégio Militar de Fortaleza (CMF) and in Ceará. A piezoelectric mat was designed to carry out physical tests, which were submitted to the passage of students and teachers from the college. It was observed that the cells lit more ease when the weight was higher, and the speed used by the pedestrian was higher. Through experiments with a surface treatment coating prototype, it was also possible to verify the efficiency of piezoelectric cells when used for lighting LED lamps.
