“…The study proposed two fitting algorithms (bitone and spline with linear interpolations) to improve the accuracy of deformation parameter measurement. The experimental results showed that the bitone and spline interpolation methods improved the measurement accuracy of the system, with a relative error lower than 4.96% and an absolute error within 0.014 mm [92]. The study concluded that the FBG array measurements using these methods improve the fitting reconstruction effect for the wing structure and stabilize the compensation effect.…”

Photonic sensing devices have become increasingly important in various fields such as agriculture, medicine, biochemical sensing, and manufacturing. They are highly sensitive and can classify minor changes in the physical and chemical properties of the ambient medium with high precision. This makes them practical in applications where accurate measurements are critical, such as medical diagnostics and environmental monitoring. In this review paper, recent advances in different types of photonic sensors are discussed, which include photonic crystal-based sensors, surface plasmon resonance-based sensors, optical fiber-based sensors, optical waveguide-based sensors, and wearable sensors. These highly fascinating sensing devices play a crucial role in countless applications and have several advantages over traditional sensors. As technology continues to advance, we can expect photonic sensors to become even more precise, versatile, and reliable.

“…In detail, the gained information allowed the estimation of the external forces and the vibration field through analyses implemented via principal component analysis (PCA) and artificial neural network (ANN) approaches. Other studies referred to the use of FBG arrays for monitoring the structural strain in order to promptly identify variations in the wing architecture by comparing the attained data with a reference numerical model [ 16 , 17 , 18 ]. A relevant application reported the use of a 54 FBG network for a medium altitude long-endurance unmanned aerial vehicle (MALE UAV).…”

The final objective of the study herein reported is the preliminary evaluation of the capability of an original, real-time SHM system applied to a full-scale wing-box section as a significant aircraft component, during an experimental campaign carried out at the Piaggio Lab in Villanova D’Albenga, Italy. In previous works, the authors have shown that such a system could be applied to composite beams, to reveal damage along the bonding line between a longitudinal stiffening element and the cap. Utilizing a suitable scaling process, such work has then been exported to more complex components, in order to confirm the outcomes that were already achieved, and, possibly, expanding the considerations that should drive the project towards an actual implementation of the proposed architecture. Relevant topics dealt with in this publication concern the application of the structural health monitoring system to different temperature ranges, by taking advantage of a climatic room operating at the Piaggio sites, and the contemporary use of several algorithms for real-time elaborations. Besides the real-time characteristics already introduced and discussed previously, such further steps are essential for applying the proposed architecture on board an aircraft, and to increase reliability aspects by accessing the possibility of comparing different information derived from different sources. The activities herein reported have been carried out within the Italian segment of the RESUME project, a joint co-operation between the Ministry of Defense of Israel and the Ministry of Defense of Italy.
