Claim 8:
9. A sensor system as claimed in claim 1, wherein the sensor transceiver system comprises a surface acoustic wave (SAW) mechanism, including:
an RF antenna, and
a transducer; and wherein
the signal guide medium comprises a piezoelectric layer and at least one reflector element attached to the piezoelectric layer operable to reflect a first acoustic signal guided by the piezoelectric layer as a second acoustic signal guided by the piezoelectric layer;
the RF antenna being connected to the transducer, and the transducer being connected to the piezoelectric layer and operable to transduce the RF interrogation signal to the first acoustic signal and to transduce the second acoustic signal to the RF response signal.
