Acquiring Wi-Fi Energy to Charge a Mobile Phone

Abstract

As a result, outdoor travelers, tourists and businessman who utilize portable electronic devices often experience battery depletion of their devices without the means of charging their device. The number of Wi-Fi access point continues to increase. There are many occasions where it is desirable to acquire energy from many radio frequency stations, while charging any electronics device through RF-DC circuit with high efficiency, for example, Wi-Fi hotspot access points. We focus on ambient radio frequency signals and power available in the ambient. This research explain, how can we charge portable devices without electrical source but means of propagating signal generated by Wireless-Fidelity (Wi-Fi) router. The research will show all the activities addressed to design a system to recover energy from electromagnetic sources presents around us like Wi-Fi routers. An energy acquiring circuit includes one loop antenna to detect RF signals and electronic board for converting RF energy to DC current. We can use to charge the battery of our portable devices by acquiring the electromagnetic energy around us.
