1. A method for measuring parameters experienced by a structure, the method comprising:

  • a) coupling at least one sensor to the structure, the at least one sensor having at least one electromagnetic resonator;

    b) transferring through at least one coupler an interrogation signal into the electromagnetic resonator to measure a select parameter and to evoke a first response signal associated with the select parameter;

    c) transferring through the same or a different coupler the response signal out of the electromagnetic resonator;

    d) measuring at least a second select parameter with the interrogation signal and to evoke at least a second response signal associated with the at least second select parameter; and

    e) transferring through the same or a different coupler the at least second response signal out of the electromagnetic resonator.
