NASA’s Integrated Vehicle Health Monitoring (IVHM) project is investigating new detection technologies that will increase aviation safety by monitoring the structural health of aerospace vehicles during flight. These new technologies must be rugged, light weight and low power. Surface Acoustic Wave (SAW) devices are low power, small and make extremely sensitive sensors for performing a variety of measurements. SAW sensors can be designed to be small passive wireless sensors that are capable of operation in harsh environments like those found inside of aerospace structures. A new SAW strain sensor model has been created that aids in the development of prototype of passive SAW strain sensors.
