An Impedance-based Structural Health Monitoring by Using Piezoelectric Transducers

Electromechanical impedance based (EMI) method is usually used health monitoring. This method requires accurately structural physical parameters and complex matrix operations. This paper presented an improved structural healthy monitoring method by using dual-piezoelectric transducers. The dual-piezoelectric transducers which have one transducer as actuator and another one as sensor were utilized to decouple electrical impedance of measured structure. Convolutional neural network (CNN) model was used to classify response signal from different structures with high accuracy.
