WIRELESS ENABLED FATIGUE SENSOR FOR STRUCTURAL HEALTH MONITORING

總結: 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.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.

Title: WIRELESS ENABLED FATIGUE SENSOR FOR STRUCTURAL HEALTH MONITORING | CAPTEUR DE FATIGUE SANS FIL POUR SURVEILLANCE DE LA SANTÉ STRUCTURELLE
Usefulness: WIRELESS ENABLED FATIGUE SENSOR FOR STRUCTURAL HEALTH MONITORING | CAPTEUR DE FATIGUE SANS FIL POUR SURVEILLANCE DE LA SANTÉ STRUCTURELLE
Summary: Fatigue sensor for monitoring health status of structural members of a structure, such as an aircraft or a bridge, e.g. for investigating elasticity of structure for monitoring its integrity over time in the service.
Novelty: Fatigue sensor for monitoring health status of structural members of structure, deployed near structural member in way it is subjected to same fatigue movements as structural member which health state needs to be monitored
