Damage Identification in Aging Aircraft Structures with Piezoelectric Wafer Active Sensors (2004, methodology): “Piezo-electric active sensors are small, nonintrusive, inexpensive piezoelectric wafers that are intimately affixed to the structure and can actively interrogate the structure (Giurgiutiu and Zagrai, 2002).”
Electro-Mechanical Impedance Method for Crack Detection in Thin Plates (2001, methodology): “Giurgiutiu and Zagrai (2001a) derived an expression where the dynamics of a sensor was incorporated and the E/M impedance spectrum was modeled to simulate the direct measurements at the sensor’s terminals.”
Damage Detection in Thin Plates and Aerospace Structures with the Electro-Mechanical Impedance Method (2005, background): “Giurgiutiu and Zagrai [ 12 ] derived an expression for the E/M admittance and impedance that incorporates both the sensor dynamics and the structural dynamics.”
Characterization of Piezoelectric Wafer Active Sensors (2000, methodology): “Further details of this experiment, including description of all the four beam measurements, error estimation (0.4% to 3.6%), and a full set of measure and predicted frequencies are given by Giurgiutiu and Zagrai (2001).”

Overview of Piezoelectric Impedance-Based Health Monitoring and Path Forward (2003, background): “Giurgiutiu and Zagrai (2000, 2002) extended the work of Sun et al. (1995b) to one-dimensional structures considering both axial and flexural vibrations.”
