摘要
A SAW sensor disposed in on a material. The sensor comprises an antenna having a sacrificial link in at least one antenna element, wherein the sacrificial link is exposed to degrading elements within or on a surface of the material, a SAW transducer responsive to an interrogation signal for generating an incident acoustic wave, a reflector responsive to the incident SAW for creating a reflected SAW, the reflected SAW received by the transducer, the transducer for creating a response signal responsive to the reflected SAW, and the response signal transmitted from the antenna, characteristics of the response signal dependent on a condition of the sacrificial link.
