Abstract
There is provided a transmission system, including a power supplying apparatus that includes 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 that includes 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, and a rectification unit that rectifies the resonated electric signal.
