WIRELESS ENABLED FATIGUE SENSOR FOR STRUCTURAL HEALTH MONITORING

Summary

The sensor keeps track of fatigue build up using breakable fingers inside. Special geometry used for fabrication of internal fingers ensure fingers break at 25, 50, 75% of the expected lifetime of the member. Wireless capability makes it easy to monitor the progress of expected lifetime without getting near the sensor. Typically structural members are replaced when they reach 75% of their expected lifetime before catastrophic failure occurs.

Technology Benefits

This is a lightweight sensor which can be glued onto critical structural members of aircraft, ship or bridge. It logs stresses encountered by the structural member during its lifetime, and gives a live indication of remaining lifetime in a wireless manner. It is well suited to aircraft, ship and bridge applications. With so many aging aircraft and bridges, there may be many applications. It simplifies routine health checks and can be used as a secondary method of check up.
