DCRS Powers Devices Over 15 Feet Away

The current wireless chargers do charge wirelessly, but are still very limited to what they can do. The wireless charging that we currently have can only charge a couple of centimeters away. A team of scientists from the Korea Advanced Institute of Science and Technology (KAIST) have made away to wirelessly transfer power over 15 feet.

The scientists from KAIST has made this possible by making what they call the Dipole Coil Resonant System (DCRS). The DCRS is made up of two identical looking 10-foot-long boxes made of compact ferrite core rods with a wire coiling around the middle of it. One of the boxes induces the voltage powering the devices around, and the other 10-foot-long box makes a magnetic field attracting the power coming from the other box to it. These two boxes are meant to be placed at two ends of a room to power anything placed in between them.

The DCRS can output 209W at over 15 feet away. That is enough power to charge 40 smartphones at the same time with a rate of 5W for every smartphone.

Chun T. Rim, engineering professor at KAIST said, “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, 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.”

This is one big step to a future of having truly wireless power sources all around. That future may still take quite a long time to surface, nonetheless we are getting closer and may one day become the norm for all power sources.
