Surface Charging Move Over – Wireless Charging Now Possible!
Gareth Andrews / 3 years ago
Wireless charging is a big selling point for a lot of devices. The ability to just place your phone or laptop down on a pad and charge without having to plug in your cable is an appealing one. The problem with this approach is it’s not truly wireless. After all the pad has a cable running from the socket and then you have to place your device on the pad and leave it there while it charges. A team from Korea hope to swap surface charging for a truly wireless experience.
A team from Korea’s Advanced Institute for Science and Technology (KAIST) have created a system where you can charge a device wirelessly. Comparing the system to WiFi the “Wi-Power” system is said to be able to power devices up to half a metre away and in any direction from the main device. The system uses two coils, the first of which (the transmitting coil) can send power to a variety of devices at the same time while the second coil (the receiving coil) doesn’t even need to be pointed at the transmitter to start charging your devices.
With it being safe around people, KAIST have formed a company to produce the technology commercially. TESLAS Inc will focus on developing the technology for everyday use, so soon you could find your phone charging itself the second you step through your front door, at least once they increase the range.
