    Abstract: A sensor device that includes an integrated sensor assembly having a surface acoustic wave (SAW) sensor disposed on a piezoelectric substrate. The SAW sensor is adapted to measure an environmental condition of an environment in response to an RF signal. The SAW sensor includes an interdigitated transducer (IDT) formed on a substrate having at least a layer of a piezoelectric material. The SAW sensor includes either one or more SAW reflectors of a second IDT formed on the piezoelectric material. The SAW sensor further includes an RF antenna formed on the piezoelectric material. The SAW sensor and the RF antenna are integrated with one another on the piezoelectric material.

    Abstract: A sensor assembly that includes a surface acoustic wave (SAW) sensor. The SAW sensor is adapted to measure a first environmental condition in response to receiving an RF signal. The SAW sensor includes a substrate having a layer of piezoelectric material. The SAW sensor further includes a interdigitated transducer (IDT) formed on the piezoelectric material. The IDT includes two comb-shaped electrodes having interlocking conducting digits in a first arrangement. The interlocking conducting digits in the first arrangement generates a first signal modulation of an RF signal received by the first IDT. The first signal modulation identifies the first SAW sensor.
