| Abstract: | This work was aimed to monitor the ice accumulation on flight structures and deice after self\|diagnosing by using embedded sensors and actuators. Wavelet analysis was applied to diagnose the emergency of ice and its grade. The deicing could be done by shape memory alloy. The method proposed could be an active deicing method, which can save energy and can be used to complex structures. |

| Keywords: | wavelet analysis piezo-electric sensor shape memory alloy deice numerical simulation |
