| 摘要 |
Devices and methods for acoustically measuring temperature and pressure are disclosed. A SAW sensor in accordance with an illustrative embodiment can include an electrode structure adapted to transmit and receive surface acoustic waves along a SAW delay line, temperature sensing means for measuring temperature along a first direction of the SAW delay line, and pressure sensing means for measuring pressure along a second direction of the SAW delay line. The SAW sensor can include an antenna adapted to wirelessly transmit and receive RF signals to and from an electrical interrogator unit that can be used to power the SAW sensor.
