Transmissão elétrica sem fio por indução eletromagnética e ressonância acoplada: os fundamentos teóricos e a física por trás desta tecnologia

Abstract

The present work studies part of the theoretical and physical concepts of the transmission of electric energy without the use of conductive wires (airborne transmission) using a very old basic concept, the electromagnetic induction. In which, by associating a properly magnetized equipment, it provides enough energy to other equipment that is magnetic resonance of its materials. The work relies on the construction of a prototype model of a battery charger for smartphones, for illustrative purposes, to aid in understanding the phenomenon of wireless energy transfer. Technology improved by researchers at the Massachusetts Institute of Technology (MIT) who had its results published in the year 2007, and made possible a significant advance in the follow-up "Witricity".
