New  Wireless Charging Technology Developed

Wouldn’t it be wonderful if you never had to plug in your phone? Well, a team of Korean scientists say that they’re one step closer to making that fantasy a reality with new wireless power transfer technology that works from over 15 feet away. And it works pretty damn well, too according Gigaom

This new system isn’t entirely new. It improves upon the basic idea for so-called Coupled Magnetic Resonance System (CMRS) developed by MIT scientists back in 2007. A team from the Korea Advanced Institute of Science and Technology, however, just announced a new option that both simplifies and improves the earlier design, extending the reach of the wireless power transfer from a little over five feet to over 15 feet.


It does so with two 10-foot-long boxes made of up compact ferrite core rods with coils of wire in the middle. One of the boxes generates a magnetic field, while the other induces the voltage. They call the set up a Dipole Coil Resonant System (DCRS).

In plain English, anything between the two boxes can tap into the system’s power. It effectively generates wireless electricity. The researchers are ambitious about the implications of such technology:

“Although the long-range wireless power transfer is still in an early stage of commercialization and quite costly to implement, we believe that this is the right direction for electric power to be supplied in the future,” said KAIST engineering professor Chun T. Rim. “Just like we see Wi-Fi zones everywhere today, we will eventually have many Wi-Power zones at such places as restaurants and streets that provide electric power wirelessly to electronic devices. We will use all the devices anywhere without tangled wires attached and anytime without worrying about charging their batteries.”

For the time being though, the setup is sophisticated and a bit unwieldy. Not destined for your local Starbucks any time soon.
