Abstract:Aiming at the development trends, the problems, and challenges met for the current non-destructive testing (NDT) and structural health monitoring (SHM) technologies, we introduce a kind of passive wireless radio frequency identification (RFID) sensor, and uncover its potential application in SHM, especially in the area of aerospace. We categorize the problems in the applications of RFID sensing technique for SHM from multiple perspectives: sensing mechanism, signal measurement, feature analysis and extraction. Moreover,the future directions for RFID sensing technique are pointed out as well. This paper can provide guidance for the application of RFID sensing technique in the area of SHM.
