POTENTIAL CLEAN ENERGY: PIEZOELECTRICITY AS AN ALTERNATIVE FOR BRAZIL

Abstract

Piezoelectricity is a form of energy generation that converts mechanical pressure into electricity, discovered by the Curie brothers. This phenomenon occurs in specific materials, such as piezoelectric ceramics (e.g. PZT), which are widely used in various applications, such as sensors, medical devices and electronics. Piezoelectricity can be exploited to generate energy from everyday movements, such as pedestrian and vehicle traffic, offering innovative and sustainable solutions. In Brazil, academic projects have demonstrated the potential of piezoelectricity. Research at Unesp has revealed that piezoelectric composites can convert the force of traffic into electricity. Studies have shown that piezoelectric pads in high-traffic areas can meet energy demands, and there is feasibility of generating energy on sidewalks, suggesting significant potential in urban areas. These initiatives highlight piezoelectricity as a promising alternative for energy generation in Brazil, contributing to energy efficiency and innovation in infrastructure. With investment in research and development, piezoelectricity could become a relevant and sustainable source of energy in Brazil.
