1. SISTEMA PARA APROVEITAMENTO DE ENERGIA VIBRACIONAL BASEADOS EM TRANSDUTORES ACÚSTICOS PIEZELÉTRICOS DE BAIXO CUSTO / MICROGENERATION BASED ON A LOW-COST PIEZOELECTRIC ACOUSTIC TRANSDUCER
This dissertation presents the development of a system for converting the mechanical energy from vibrations into electrical energy. The conversion is performed in a low-cost piezoelectric transducer, commonly known as buzzer. The main purpose of this system is to charge, or to extend the time between charges, of chargeable batteries up to 2V. In order to con
