Embedded Self-Sensing Piezoelectric Active Sensors for On-Line Structural Identification

  title={Embedded Self-Sensing Piezoelectric Active Sensors for On-Line Structural Identification},
  author={Victor Giurgiutiu and Andrei N. Zagrai},
The benefits and limitations of using embedded piezoelectric active sensors for stru identification at ultrasonic frequency are highlighted. An analytical model based on s tural vibration theory and theory of piezoelectricity was developed and used to predic electro-mechanical (E/M) impedance response, as it would be measured at the piez tric active sensor’s terminals. The model considers one-dimension structures and acc for both axial and flexural vibrations. Experiments were conducted on… CONTINUE READING
