The concept of using piezoelectric (PZT) nanoactive fiber composites (NAFCs) with interdigitated electrodes as acoustic emission (AE)sensors for structural health monitoring (SHM) applications is demonstrated. As reported by Yong Shi and co-workers, the high sensitivity, microscale dimensions, low weight, large flexibility, low cost, and anisotropic sensitivity cause these PZT NAFCs sensors to have promising applications in health monitoring.
