Outline of Final Research Achievements

We have proposed a new wireless sensor tags to evaluate the fatigue damage. The basic sensor principles is based on the fracture of RFID tags, and the garbled data. The fatigue damage parameters such as stress range and cyclic number of structures can be measured by reading the data in RFID tag wirelessly. These tags can be easily installed without wiring and batteries.
Our approaches are excellent in economic efficiency and convenience, and it is very promising for one of an alternative to conventional non-destructive inspection technique. It expects to be capable of becoming one of the resolution approach to the aging problem of the infrastructure.
