Estudo de captação de energia utilizando palmilhas acopladas a pastilhas piezoelétricas

Abstract

In the context of the evolution of the global energy matrix, the demand for technological innovations within the study of electrical energy and its derivations is essential for the advancement of sustainable solutions, especially in a scenario of increasing technological dependence. This work presents an alternative to the development of a vibration energy capture system, based on the use of piezoelectric inserts in the insole of shoes. The main objective is to evaluate the use of mechanical energy generated by human movement during walking for conversion into electrical energy, which can be stored or used to power portable electronic devices. The mechanism consists of three main components: piezoelectric inserts, which are devices that convert mechanical energy into electrical energy when subjected to pressure; the insoles, which are adapted to fix the piezoelectric inserts to the sole of the shoe; and the Arduino, which is a microcontroller board that is used to collect data from the piezoelectric inserts. The proposed prototype was developed and tested at the Federal Technological University of Paraná, Francisco Beltrão campus. As a result, it was observed that the system is capable of generating a voltage of up to 5 volts, which is enough to power low-power portable electronic devices. The improvement of the proposed method contributes to the creation of future research within the field of piezoelectric energy and the development of high power.
