Abstract
The present disclosure provides a new and improved temperature compensated surface-launched acoustic wave (SAW) strain sensor using multiple reflectors in SAW devices mounted on a split-carrier package that provides complete isolation from strain for a temperature sensing portion of the device, while exposing a strain sensing portion of the device to both strain and temperature, with the influence of temperature being common to the various portions of the device, and a single acoustic reference with respect to which multiple differential acoustic measurements can be made, to provide inherently temperature-compensated strain measurements.
