Patent attributes
A power transmitter and a power receiver are disposed with a space provided therebetween, and a power transmission device produces an electromagnetic field that periodically changes using the AC current in a space and forms a vibrating electromagnetic resonance field in which the space itself has energy. By obtaining electrical energy from the resonance field, a power reception device produces a resonance current, and a new electromagnetic resonance field is formed by the resonance current. The power transmission device or the power reception device is constituted of a conductor having a Peano curve shape that covers a surface having a given spread by passing through all regions obtained by dividing the surface having a given spread without intersecting with itself, and the electromagnetic field energy of a space in the periphery of the fractal-shaped device is increased.
