Document Type and Number:
WIPO Patent Application WO/2014/034491
Kind Code:
A1
Abstract:
The electric power transmission device of the present invention for transmitting electric power wirelessly in a good conductor medium is provided with a power transmitting unit for transmitting electric power wirelessly, and a power receiving unit for intromitting wireless electric power transmitted from the power transmitting unit. The power transmitting unit and the power receiving unit are provided with an electric power transmission coil and a containment unit having a dielectric for covering the electric power transmission coil, and transmit electric power by oscillating at a frequency determined by the impedance of the power transmitting unit, the impedance of the power receiving unit, and the impedance of the good conductor medium.
