Abstract: PURPOSE: A wireless power transmission device and method for reducing radiated power of a magnetic resonator are provided to transmit energy by selecting a frequency having relatively low radiated power. CONSTITUTION: A signal generator(102) generates a frequency signal used for wireless energy transmission from general commercial AC powder. A power amplifying unit(104) amplifies the frequency signal. A signal detection unit(106) transfers the amplified signal to a magnetic resonator for wireless energy transmission and detects a radiated signal caused by the magnetic resonator. A standing-wave ratio calculation unit(108) calculates a standing-wave ratio from the detected signal. A control unit selects the frequency having the lowest standing-wave ratio using the standing-wave ratios calculated by the standing-wave ratio calculation unit.

Abstract: PURPOSE: A flexible electric device is provided to effectively alleviate the bending phenomena of a substrate. CONSTITUTION: A first substrate(100) has flexibility. A second substrate(110) is separated to the first substrate. The ground particles(106) separates the first and second substrate between the first substrate and the second substrate. Adhesives(102) are arranged along the edge of the second substrate. At least one part of adhesive is opened. The adhesive sticks to the first and second substrate.
