Packaging Considerations for a Surface Acoustic Wave Strain Sensor

In this paper, packaging effects for a one port surface acoustic wave resonator (SAWR) strain sensor are considered. A one port non apodized SAWR fabricated on AT-X quartz is hermetically packaged using commercial off the shelf packages and standard strain gauge adhesives. The package geometry is such to allow the final device to act as a modular general purpose SAWR strain sensor. Calibration of the packaged sensor was performed for a range of temperatures and loading conditions and the results are presented within this paper.
