Many technologies have bee n considered during these years (ultrasounds, optic fiber, Eddy current, electromagne tic, imaging, impedance measurements,...) and many solutions for fault detection algorithms, types of sensors, techniques for conducting the tests, etc. have also been introduced. Even though the SHM technology is almost mature, just a few SHM experimental systems are frequently used. SHM systems usually focus on structures with no limitation on volume r weight. The SHM systems are still under test in applications for aircraft and wind generators, where the weight and volume is critical. One of the most applied technologies in SHM is the monitoring through surface ultrasonic waves or Lamb waves. The main advantages of this technique are the low power consumption of the sensors and the capability to cover large areas using few se nsors. The ultrasound technique for SHM consists of a system composed of several modules: si...
