Now, Remotely charge your Mobile Phone

Scientist have succeeded in creating a gadget that can charge about 40 cell phones at the similar time, considering the fact, even if the power source is 5 meters away.

April 16, 2014 at the KAIST grounds, Professor Chun T. Edge and his team showcased an unbelievable variation in the separation that electric force can travel remotely. This is the great improvement which specifies that in the distance that electric power can travel wirelessly. This group is working in Nuclear and Quantum Engineering department at KAIST Daejeon, Republic of Korea.

Professor and his team developed the “Dipole Coil Resonant System (DCRS)” for an enlarged range of inductive force transferal, up to 5 meters of range between transmitter and recipient curls.

Since MIT’s (Massachusetts Institute of Technology) demonstration of the Coupled Magnetic Resonance System (CMRS) in 2007, which employed a magnetic field to exchange energy for a space of 2.1 meters, the expansion of long-distance remote power exchange has pulled in much attention for further research.

Flexible and slim with a dimension of 3 m long, 10 cm in breadth, and 20 cm in height, DCRS is suggestively more compact than CMRS. The structure has a low Q factor of 100, signifying 20 times stronger against atmospheric changes, and works well at a low frequency of 100 kHz.

The group piloted several experiments and achieved guaranteeing effects: for illustration, under the operation of 20 kHz, the extreme output power was 1,403 W at a 3-meter distance, 471 W at 4-meter, and 209 W at 5-meter. For 100 W of electric energy transfer, the whole system power efficiency was 36.9 per cent at 3 meters, 18.7 per cent at 4 meters, and 9.2 per cent at 5 meters.
