TL;DR: The requirements for practical implementation and use of structural health monitoring systems in aircraft application, state-of-the-art techniques for solving some practical issues, such as sensor network integration, scalability to large structures, reliability and effect of environmental conditions, robust damage detection and quantification are discussed.

TL;DR: Acellent Technologies as mentioned in this paper developed a system for actively and passively interrogating the health of a structure through an integrated network of sensors and actuators, which can be used for monitoring structural condition and for detecting damage while the structures are in service.

TL;DR: In this article, a hybrid approach for characterizing fatigue damage was developed, using two genres of damage indices constructed based on the linear and the nonlinear features of acousto-ultrasonic waves.

TL;DR: This study has yielded a quantitative characterization strategy for fatigue cracks using embeddable piezoelectric sensor networks, facilitating deployment of structural health monitoring which is capable of identifying small-scale damage at an embryo stage and surveilling its growth continuously.

TL;DR: In this paper, a method for integrating piezoelectric sensor networks into a composite structure during different fabrication processes, including the resin transfer molding (RTM) and filament winding processes, is examined.
