Steel bridge fatigue crack detection with piezoelectric wafer active sensors [PDF]
SPIE Proceedings, 2010 Piezoelectric wafer active sensors (PWAS) are well known for its dual capabilities in structural health monitoring, acting as either actuators or sensors. Due to the variety of deterioration sources and locations of bridge defects, there is currently no single method that can detect and address the potential sources globally.

Multi-mode Damage Detection Methods with Piezoelectric Wafer Active Sensors [PDF]
Journal of Intelligent Material Systems and Structures, 2008 PWAS are small and non-invasive transducers that can be easily affixed to a structure to interrogate it at will. Their wideband non-resonant properties make them advantageous candidates for multiple modes structural health monitoring (SHM) and nondestructive evaluation (NDE) simply by changing the driving frequencies.
