Structural health monitoring using smart sensors
Smart sensors densely distributed over structures can provide rich information for structural health monitoring using their sensing,computational,and wireless communication capabilities.Though smart sensor technology has seen substantial advances recently,the implementation of smart sensors on full-scale structures has been limited.Interdisciplinary efforts to address issues in sensors,networks,and application specific algorithms have only now begun to germinate.This paper addresses each of these issues and then combines the development outcomes to produce a structural health monitoring(SHM)system employing a network of smart sensors.This research adopts Intel’s Imote2 because of its ability to meet the demands of data intensive applications such as SHM.Simulation data is first used to examine the numerical validity of implementing a SHM system on the Imote2s.To demonstrate the performance of the proposed SHM system,experimental studies are conducted using a three-dimensional truss structure.The system is investigated from sensing,network,and SHM algorithm perspectives.
