Sistema de captación de energía piezoeléctrica para aprovechar las vibraciones generadas en zonas transitadas

Abstract

This project aims to design and implement a piezoelectric energy harvesting system through intelligent tiles, focused on fostering energy sustainability and reducing the environmental impact caused by disposable batteries. The hypothesis states that the mechanical energy generated by footsteps can be transformed into useful electrical energy, contributing to the extension of battery life in low-power sensors. The justification lies in the need to propose distributed generation alternatives that optimize resources and promote efficiency in smart buildings. For the development of the project, the problem was identified, the environment was analyzed, and the structure was designed under specific physical restrictions. An electrical system was implemented using piezoelectric disc-type materials, rectification circuits, buck regulators, and charge controllers, complemented by structural simulations and electrical validations carried out under technical standards of safety and performance. The results demonstrated the feasibility of the proposal, showing an energy conversion sufficient to power low-consumption devices and the preparation of a preliminary cost scheme. In conclusion, the project confirms that piezoelectric harvesting is an efficient, safe, and adaptable alternative within the framework of energy sustainability. Key words: Piezoelectric, vibrations, batteries, sensors, sustainability.
