Diseño e Implementación de un Prototipo Portable de Generación Piezoeléctrica

This document presents a research on the design and evaluation of a piezoelectric energy harvesting system using a mat with multiple piezoelectric elements. The research begins with an introduction on the importance of developing alternative sources of renewable energy for portable electronic devices. Subsequently, a literature review on human motion energy harvesting technologies is presented, with a focus on piezoelectric materials. The methodology describes the design of a piezoelectric mat prototype consisting of a rubber layer, an acrylic sheet, and multiple piezoelectric elements connected in parallel to an energy harvesting circuit. Tests were conducted to characterize the response of the piezoelectric sensors and evaluate the energy harvesting system under different configurations. The results indicate that a single element generated 18,59 μJ, while 10 connected elements produced 297,4 μJ with a voltage of 0,57 V. Furthermore, the system enables remote data acquisition through the IoT platform Thingspeak.
