1. A system for wirelessly transferring power, comprising:

  • a first device configured to be coupled to a power supply source and including a first resonant circuit configured to resonate at a first frequency corresponding to a wavelength; and

    a second device that includes a battery and a second resonant circuit configured to resonate at said first frequency, the first and second resonant circuits being spaced apart by a distance smaller than the wavelength corresponding to said first frequency, said first device being configured to wirelessly transfer to said second device a first signal having a power configured to charge said battery, wherein;

    said first device comprises;

    a first modulator configured to modulate the frequency of said first signal for transferring data from said first device to said second device simultaneously with the power transfer; and

    a first demodulator configured to demodulate a second signal from said second device; and

    said second device is configured to transmit the second signal to the first device and comprises;

    a second modulator configured to modulate a frequency of the second signal; and

    a second demodulator configured to demodulate the first signal sent from said first device, to obtain the transmitted data, wherein the first and second devices are configured to provide full-duplex communication using the first and second modulators and first and second demodulators.
