Electricity from Air: An efficient way of Wireless Power Tapping

Abstract

Electromagnetic (EM) radiations are emitted by almost all electrically energized devices such as laptops, smartphones, wireless routers, Wi-Fi, etc. The radiations emitted from the antennas of these electrically charged bodies, when exposed to human tissue without any electromagnetic compatibility protection, can cause severe damage. The presence of electrically charged components is nevertheless increasing day by day and, in turn, increasing the presence of electromagnetic radiation. In present days, electromagnetic radiations consist of radio waves in higher percentages and are present abundantly everywhere. These electromagnetic radiations to be a source of renewable source of energy. The primary aim of this work is to fabricate an electromagnetic collector to energize a battery by absorbing surrounding natural radiation. The gatherer should assemble free power from pretty much anything, including PCs, cell phones, overhead electrical cables, iceboxes, or even the outflows from Wi-Fi or cell phone. This is achieved by the process of wireless power transfer (WPT). One harvester might not be useful, but several such harvesters put together with power electronic converters can generate high output power. A case study is carried out, and the same is demonstrated using a simulation study on the MATLAB/Simulink platform.
