N2 - Economic and reliable online health monitoring strategies are very essential for safe operation of civil, mechanical and aerospace structures. Furthermore, a PZT sensor self-diagnostic and validation procedure is quite important issue for successful impedance-based SHM system's implementation. This study presents online sensor self-diagnosis technique over structural health monitoring (SHM) strategies using wireless impedance sensor nodes. The wireless impedance sensor node incorporating a miniaturized impedance measuring chip, a microcontroller, and a radio-frequency (RF) telemetry is equipped with the capabilities for temperature-sensing, multiplexing of several sensors, and local data analysis. A temperature effects-free sensor self-diagnosis algorithm is embedded into the sensor node and its feasibility is examined from the experiments monitoring the integrity of each piezoelectric sensor on a wireless sensor network.
