TL;DR: In this paper, a manufacturing method was developed for integrating a network of distributed piezoceramic actuators/sensors onto laminated carbon/epoxy composite structures.

TL;DR: Safety and reliability are critical factors in the usage of in-service structures and current inspection techniques such as X-ray, ultrasound, c-scan and thermal imaging are time consuming, expensive and rely heavily on human interpretation.

TL;DR: Hybrid piezoelectric/fiber-optic (HyPFO) sensor sheets are undergoing development and are intended for use in nondestructive evaluation and long-term monitoring of the integrity of diverse structures, including aerospace, aeronautical, automotive, and large stationary ones.

TL;DR: A built- in diagnostic technique based on a distributed sensor network is presented for composite structures that uses the built-in sensors to measure the response of the structures and process the measured signals to interpret the changes of signals at two different times in terms of physical change of the structure.
