Development of an impedance-based wireless sensor node for structural health monitoring (2007, methodology): “A very promising SHM technique that utilizes the benefits of piezoelectric materials is impedance-based health monitoring methods (Sun et al 1995, Park et al 2000, 2003, Giurgiutiu et al 2002, 2004, Bhalla and Soh 2003, 2004).”
Performance assessment and validation of piezoelectric active-sensors in structural health monitoring (2006, methodology): “Impedance-based structural health monitoring techniques (Park et al 2003, Bhalla and Soh 2003, Giurgiutiu et al 2004) indirectly measure the mechanical impedance of a structure over selected frequency ranges for SHM.”
Single Mode Tuning Effects on Lamb Wave Time Reversal with Piezoelectric Wafer Active Sensors for Structural Health Monitoring (2007, methodology): “Most of the methods used in conventional guided-wave NDE, such as pitch-catch, pulse echo, and phase arrays, have also been demonstrated experimentally with PWAS [1, 2, 5].”
