INTEGRATED RF POWERED PLATFORM FOR STRUCTURE HEALTH MONITORING (SHM) OF AIRCRAFT USING NANOSTRUCTURED SENSING MATERIAL

Abstract:

Aircraft sensors are described which record a condition of interest of the aircraft during flight without being powered. The sensor may include a sensing element comprising a nanostructure material which permanently changes state in connection with a permanent change in state of the aircraft, thus recording the condition of the aircraft. When the aircraft is on the ground, the recorded condition is read from the sensor using a wireless radio frequency (RF) reader, rather than communicating the recorded state during flight. In this manner, the sensor operates without interfering with the aircraft while in flight.
