Abstract
A wireless power transmission device and method are provided. An amount of power transmitted wirelessly by the wireless power transmission device may be controlled based on information to be transmitted by the wireless power transmission device, such that the information may be transmitted without using any additional device for information transmission. Additionally, an internal impedance of a terminal may be controlled based on information to be transmitted by the terminal, and a reflected wave of a transmission signal transmitted by the wireless power transmission device may be then controlled, such that the information may be transmitted without using any additional device for information transmission. Therefore, no further device may be desired, and thus a power consumption amount may be reduced, and there may be no need to match a communication part for information exchange with a transmission part for wireless power transmission.
