Wireless Electric Concept and Application in a Living Room

The exploration of wireless technology nowadays has widened into a bigger
area. One of the areas that is currently being researched by companies and
universities around the world is supplying power to the electrical appliances
wirelessly. The research is being done since the effect of the technology beneficial to
both the human and sciences where power can be distributed wirelessly around the
globe. This project presents an overview of a design and implementation of Wireless
Electric Concept and Application in a Living Room. Research and study is carried
out on how signal and energy in the air can be tapped and converted into useful
energy which later can be used to supply power to electrical appliances. The
approach of this work starts by harvesting Radio Frequency (RF) signal that is
available in the air using RF energy harvesting circuit. This circuit collects or harvest
energy in the air and converts them into electricity. It is done by using the antenna to
capture the RF energy and the charge-pump circuit to convert and maguify the input
signal in AC to larger output in DC. This DC output is then used to power lowvoltage
equipments in the living room. Simulation work using PSPICE full edition
was done to develop the concept and later was used as guidelines in developing the
prototype.
