1. A method of powering and controlling sensors at a distance using acoustic wave energy, the method comprising:

  • providing a transmission arrangement comprising an acoustic signal generator;

    providing a receiving arraignment comprising an acoustic signal receiver;

    providing a least one sensor which is electrically coupled to the signal receiver;

    providing a waveguide spanning between and engaged to the signal generator and the signal receiver;

    generating an acoustical wave comprising a control signal with the signal generator, the acoustical wave having sufficient strength to provide operating power to the sensor, and transmitting the acoustical wave from the signal generator to the signal receiver through the waveguide;

    receiving the acoustical wave at the signal receiver, and converting the acoustical wave into an electrical current comprising a converted control signal;

    using the electrical current to power the sensor; and

    using the converted control signal to control the sensor.
