The present invention relates to a smart two-dimensional(2D) magnetic resonance wireless power transmission and reception device which has a resonance coil and a resonance loop flattened on the sample plane. The present invention can solve the problems regarding a narrow application scope and difficulties in realizing a compact wireless power transmission and reception device due to the large volume and heavy weight caused by the three-dimensional resonance coil and loop in the X-axis, Y-axis, and Z-axis configuring a wireless power transmission system in a conventional magnetic resonance scheme. The present invention also solves the problems regarding low power efficiency due to unstable wireless power waves caused by changing resonance frequencies and impedance when the device changes the location to transmit power wirelessly by using an electromagnetic resonance method. Accordingly, the resonance coil and resonance loop can be in a flat spiral line shape in a two-dimensional structure including the X-axis and Y-axis. The smart 2D magnetic resonance wireless power transmission and reception device can wirelessly transmit power at the resonance frequency of 1 to 10 MHz and at the short distance of 5 to 50 cm, reduce the volume and weight by 80% compared to that of a conventional device, and manufacture a flexible substrate made of nylon, cotton, polyester, polypropylene, and acrylate materials. Accordingly, the smart 2D magnetic resonance wireless power transmission and reception device has excellent flexibility, resonance patterns formed on other surfaces, and stable inductance and capacitance value to provide a transmission efficiency enhanced by 70% compared to a conventional counterpart as well as ensuring wide applications in IT devices, clothing, and medical fields by flattened designs, weight reduction, and volume reduction. |
