Abstract

Smart sensors densely distributed over structures can provide rich information for structural monitoring using their computational and wireless communication capabilities. Though smart sensor technology has seen substantial advances during recent years, implementation of smart sensors on full-scale structures has not been prevalent yet; interdisciplinary efforts to address issues in sensors, networks and application specific algorithms have just germinated. Each of these issues is addressed and then the development outcomes are combined to materialize a SHM system with networks of smart sensors. Intel Mote 2 (Imote2) is employed as a smart sensor platform because its high computational and wireless communication performances are considered advantageous for SHM applications. Simulation data is first utilized to examine the numerical validity of networks of Imote2s as a data processing system. Then Imote2s are installed on a three-dimensional truss structure to demonstrate the performance of the SHM system consisting of smart sensors; the system is investigated from sensing, network, and SHM algorithm perspectives.
