O pavimento como instrumento de geração de energia para o desenvolvimento sustentável de cidades inteligentes

Abstract

Sustainability has become a concept widely studied and applied, being linked to sustainable development, becoming possible only with the joint consideration of the social, economic and environmental spheres. Based on this assumption, the road pavement emerges as a sustainable alternative for generating energy that does not depend on the natural system. It’s seen as the meeting point of people and vehicles, obtaining electrical energy through the transformation of mechanical energy transmitted by the vehicle to the pavement, using piezoelectric cells or the conversion of solar energy through photovoltaic panels or heat exchanger systems. Therefore, this work was developed based on the instigation of pavement usefulness as a mechanism to contribute to the sustainable development of smart cities, in order to show the possibility of its use with the purpose of reducing the environmental impact related to energy. The methodology was carried out by means of an exploratory study and the realization of simulations, with the proposition of a prototype and simulation of application in a real section. It was possible to identify the main publications about pavement as an instrument of energy harvesting, also listing its advantages and disadvantages. In addition, it was possible to measure which geometric properties have a direct influence on the electrical potential, as well as suggest places of application from the analysis of frequency and load submitted to the piezoelectric discs.
