Patent ID: 8421272

Claim:
A transmission system, comprising: a power supplying apparatus, including: an AC signal generation unit that generates an AC signal; a first resonance unit that has an induction component and/or a capacitance component and resonates the AC signal generated by the AC signal generation unit; and a power supplying electrode that externally radiates the resonated AC signal as a potential difference in an electrostatic field, and a power receiving apparatus, including: a power receiving electrode that generates an electric signal by sensing the potential difference in the electrostatic field; a second resonance unit that has an induction component and/or a capacitance component and resonates the electric signal generated by the power receiving electrode; a rectification unit that rectifies the resonated electric signal; a power measurement unit that measures a power value of power generated after the electric signal rectified by the rectification unit; and a control unit that controls the induction component and/or the capacitance component of the second resonance unit based on the power value measured by the power measurement unit.
