Surface acoustic wave (SAW) technology can be used to create a variety of different sensors, including strain, chemical, pressure, and temperature. These sensors can be configured to be passive and wireless, which could be useful in aerospace applications. NASA performs tests on the ground, in wind tunnels, and on aircraft during flight and in space. Many of these tests would benefit from the reduction or removal of wires during testing through the use of passive wireless sensors, such as SAW devices. This paper presents a SAW strain sensor for structural health monitoring and other aerospace applications.
