Classification: CPC G | IPC G

Claim 9:
10. A sensor assembly comprising:
a first surface acoustic wave (SAW) sensor disposed on a substrate comprising at least a layer of a piezoelectric material, wherein the first SAW sensor is adapted to measure an environmental condition of an environment responsive to receiving a first RF signal, the first SAW sensor comprising:
a first interdigitated transducer (IDT) formed on a first region of the piezoelectric material, the first IDT to generate a first SAW based on the environmental condition responsive to receiving the first RF signal; and
a first plurality of SAW reflectors communicatively coupled to the first IDT and formed on a second region of the piezoelectric material;
wherein the first plurality of SAW reflectors have a first spatial arrangement that causes the first SAW reflected from the first plurality of SAW reflectors and back to the first IDT to have a first signal modulation that identifies the first SAW sensor.
