Claim 4:
5. A method for non-destructive testing of an object using a multi-frequency wireless sensor for non-destructive testing of a test object, the sensor comprising an ultrasound transducer having a plurality of operating frequencies, a first induction coil electrically coupled to the ultrasound transducer, a second induction coil, and a capacitance connected in parallel with the second induction coil such that the wireless sensor can operate at a first operating frequency or a second operating frequency when the sensor is excited by a remote device, the method comprising:
installing the sensor in or on the object to be tested;
exciting the sensor with a guided wave excitation signal;
receiving from the sensor a response to the guided wave excitation signal; and
recording the response received from the sensor as a unique identifier for the sensor.
