Research on Miniaturized and Portable Impedance-measuring Device for Structural Health Monitoring
Electromechanical impedance technique which based on smart material is a new method for structural damage detection,and it could be widely applied in structural health monitoring field.However,a very expensive and bulky analyzer is being used to measure the impedance,which is not practical for on-line system.Therefore,this paper developed a device that can measure the electric impedance using small modular electric components and reasonable circuit.Experiments are carried out to test the aluminum beam crack.Results indicate that the device can measure the electric impedance and detect the damage effectively.The proposed method provides a solution to miniaturize the impedance-measuring equipment and reduce the cost of measurement.
