You would be able to charge your mobile device by using Wi-Fi charging System. So now you don’t have to bother with the less battery at any place in your home, you can go anywhere within the range your charger will connected with your phone. With this technology, so long as mobile users stay in a selected range where the charging is available, e.g., the Wi-Fi Power zone, the device without being tied to a charger, will pick up power automatically, as needed.
The system developed by The Korea Advanced Institute of Science and Technology (KAIST) in South Korea is capable of charging multiple mobile devices simultaneously and with unparalleled freedom in any direction, even while holding the devices inflight or half a meter away from the power source.
The technology works as Wi-Fi works for Internet connections, researchers said. The research team led by Professor Chun T Rim of the Nuclear and Quantum Engineering Department at KAIST effectively showcased the technology on July 7 at a lab on KAIST’s campus. They used high-frequency magnetic materials in a dipole coil structure to build a thin, flat transmitter.
Either 30 smartphones with a power volume of one watt each or 5 laptops with 2.4 watts each can be at the same time and wirelessly charged at a 50 cm distance from the transmitter with six degrees of freedom, irrespective of the devices’ three-axes positions and directions. This means that the device can receive power all around the transmitter in three-dimensional space.
Although wireless-power technology has been realistic to smartphones, it could not offer any significant advantages over traditional wired charging because the devices still require close contact with the transmitter and a charging pad. Until now, all wireless-charging technologies have had difficulties with the problem of short charging distance, typically less than 10 cm, as well as charging settings that the devices should be positioned in a static point.
