ABSTRACT:
A surface wave device can be configured to include an interdigital transducer and an acoustic coating formed upon a piezoelectric substrate, wherein the interdigital transducer is selected to introduce negligible electrical coupling to surface waves thereof. Additionally, an antenna can be integrated with the surface wave device, wherein the antenna receives one or mores signals, which excite the acoustic wave device to produce multiple modes frequency outputs in which temperature and pressure effect changes are separated from one another for analysis thereof.
