Classification: CPC G | IPC G

Claim 0:
1. A sensor assembly comprising:
a first surface acoustic wave (SAW) sensor adapted to measure a first environmental condition responsive to receiving a first RF signal, the first SAW sensor comprising:
a first substrate comprising at least a layer of a piezoelectric material; and
a first interdigitated transducer (IDT) formed on the piezoelectric material, the first IDT comprising two comb-shaped electrodes comprising interlocking conducting digits in a first arrangement, wherein the interlocking conducting digits in the first arrangement generate a first signal modulation of the first RF signal received by the first IDT, wherein the first signal modulation identifies the first SAW sensor, and wherein the first arrangement comprises:
at least two digits from the same comb-shaped electrode of the two comb-shaped electrodes arranged adjacent to each other, or
a first portion of the first arrangement with a first spacing between adjacent digits, and a second portion of the first arrangement with a second spacing between adjacent digits, different from the first spacing.
