4 Passive Sensors Monitor the health of the structure over time Sensor can listen to the structure but can not interact with the structure SHM Technology Active Sensors Interact with the structure by sending a signal and then listen to the structure s response 4

5 Impedance-based Structural Health Monitoring New Structural Health Monitoring (SHM) method. Real-time structural damage assessment. The electrical impedance of the PZT material can be directly related to the mechanical impedance of a host structural component. The change in the structure s impedance is attributed to the change in integrity of the structure due to damage. The real part of electric impedance is more reactive to damage or changes in the structure s integrity than the imaginary part Electromechanical Impedance is Quality Control Method 0 Re Z, Ohms mm Crack Rivet head Piezoelectric active sensors #1 #2 #3 # Frequency, khz Sensor 1 Sensor 2 Sensor 3 Sensor 4 5 From Dr. Giurgiutiu and Dr. Zagrai s paper
