A 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. Due to their high sensitivity, microscale size, low weight, large flexibility, low cost, and anisotropic sensitivity, the PZT NAFCs sensors have a promising application in health monitoring by integrating them into composites.
