    摘要： A load impedance decision device, a wireless power transmission device, and a wireless power transmission method are provided. At least one of a distance and an angle between two resonators may be measured. A load impedance may be determined based on at least one of the measured distance and the measured angle. When the distance between the two resonators changes, a high power transfer efficiency may be maintained without using a separate matching circuit. Where the load impedance is determined, a test power may be transmitted. Depending on a power transfer efficiency of the test power, the load impedance may be controlled and power may be wirelessly transmitted from the source resonator to the target resonator.

    摘要： An energy harvest is disclosed. The disclosed energy harvest includes: a first charging member including a plurality of first protruding parts; and a second charging member including a plurality of second protruding parts arranged between the first protruding parts and including a material different from that of the first protruding parts. When at least one of the first and second charging members moves, side surfaces of the first protruding parts and side surfaces of the second protruding parts come into contact with each other, or gaps between the side surfaces of the first protruding parts and the side surfaces of the second protruding parts are changed. The energy harvest generates electrical energy from the contact or the gap change.

    摘要： A wireless power transceiver that is disposed between a source resonator and a target resonator and that may increase wireless power transmission efficiency is provided. The wireless power transceiver may include a power receiver that includes a receiving resonator that receives an inbound power from a source resonator, a power transmitter that includes a transmitting resonator that transmits an outbound power to a target resonator, and a coupling controller to control a coupling frequency between the target resonator and the transmitting resonator.
