Wireless remotely readable and programmable microsensors and MEMS for health monitoring of aircraft structures

摘要

Microsensors and Microelectromechanical Systems (MEMS) are currently being applied to the structural health monitoring of critical aircraft components. The approach integrates acoustic emission, strain gauges, MEMS accelerometers and vibration monitoring devices with signal processing electronics to provide real-time indicatiors of incipient failure of aircraft components with a known history of catastruophic failure due to fracture.
