Claim 13:
14. An integrated sensor device 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 incoming 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 incoming RF signal; and
a second SAW sensor disposed on the piezoelectric material, wherein the second SAW sensor is adapted to measure the environmental condition of the environment responsive to receiving the first incoming RF signal or a second incoming RF signal, the second SAW sensor comprising a second IDT formed on a second region of the piezoelectric material, the second IDT to generate a second SAW based on the environmental condition responsive to receiving the first incoming RF signal or the second incoming RF signal, wherein the second IDT is further to receive the first SAW from the first IDT and generate a first oscillating electric potential associated with a first acoustic frequency of the received first SAW, and wherein the second IDT is coupled to an RF antenna which is to output a first outgoing RF signal in accordance with the first oscillating electric potential; and wherein the first SAW sensor is adapted to operate in a first frequency range and the second SAW sensor is adapted to operate in a second frequency range that is different than the first frequency range, wherein the first SAW sensor is disposed on a first surface of the substrate and the second SAW sensor is disposed on a second surface of the substrate.
