Electrical Impedance Spectroscopy-Based Defect Sensing Technique in Estimating Cracks

Electrical Impedance Spectroscopy-Based Defect Sensing Technique in Estimating Cracks

A defect sensing method based on electrical impedance spectroscopy is proposed to image cracks and reinforcing bars in concrete structures. The method utilizes the frequency-dependent behavior of thin insulating cracks: low-frequency electrical currents are blocked by insulating cracks, whereas high...
