“…Viable alternative SHM techniques, whose potential usage in the monitoring of aeronautic components is being studied, include optical fibres-based systems [ 21 , 22 , 23 , 24 , 25 , 26 ], systems founded on the measurement of impedance, based on piezoelectric patches attached to the structure acting, again, simultaneously as actuators and sensors [ 27 , 28 ], systems based on the direct measurement of structural vibrations and the respective modal parameters of the studied structure, which is especially common in research concerning autonomous sensor nodes using the wireless transmission of data [ 29 ], and smart skin systems based on lightweight and highly stretchable piezoelectric sensor networks used for high accuracy monitoring of impacts on the aircraft [ 30 , 31 ].…”

With the aim of increasing the efficiency of maintenance and fuel usage in airplanes, structural health monitoring (SHM) of critical composite structures is increasingly expected and required. The optimized usage of this concept is subject of intensive work in the framework of the EU COST Action CA18203 “Optimising Design for Inspection” (ODIN). In this context, a thorough review of a broad range of energy harvesting (EH) technologies to be potentially used as power sources for the acoustic emission and guided wave propagation sensors of the considered SHM systems, as well as for the respective data elaboration and wireless communication modules, is provided in this work. EH devices based on the usage of kinetic energy, thermal gradients, solar radiation, airflow, and other viable energy sources, proposed so far in the literature, are thus described with a critical review of the respective specific power levels, of their potential placement on airplanes, as well as the consequently necessary power management architectures. The guidelines provided for the selection of the most appropriate EH and power management technologies create the preconditions to develop a new class of autonomous sensor nodes for the in-process, non-destructive SHM of airplane components.

“…Eight polyvinylidene fluoride (PVDF) patches were used as the sensor in the experimental study on active vibration control of a laminated paraboloidal shell (Yue et al, 2017). Gao et al (2017) utilized fiber Bragg grating (FBG) sensors to achieve the vibration shape reconstruction of an aircraft model. In the experimental study of a free-edge rectangular sandwich plate, the vibration is sensed by the Macro-Fiber Composite (MFC) (Zippo et al, 2015).…”

A non-contact vibration measurement and control system for a piezoelectric-patched flexible cantilever plate is presented, using laser displacement sensors. Two laser displacement sensors are utilized to detect the deflection information of the two corners of the end of the flexible board, due to its high measurement accuracy for the small amplitude residual vibration. The vibrations of the first bending and torsional mode of the flexible plate can be extracted from the combined information. To achieve a desirable performance for the active vibration control, a kind of sliding mode predictive control strategy is developed to damp the vibration quickly. Simulation of the controller on bending and torsional vibration is conducted, based on the model built with finite element method. Furthermore, a piezoelectric flexible cantilever plate experimental setup is constructed. Experiments are conducted. The results of simulation and experiment both demonstrate the effectiveness of presented control scheme, compared with proportional and derivative control; the sliding mode predictive control can attenuate the vibration more quickly, particularly for the small amplitude residual vibration.

“…In recent decades, FBG sensors have been widely used in various fields. For instance, they can be used in intelligent materials [1][2][3][4] and structural health monitoring [5] to measure physical variables including stress, strain, temperature, velocity, and vibration. Their wide application can be attributed to their advantages over general electrical sensors, because they are favored by their light weight, small size, strong durability, high sensitivity and good immunity to electrometric interference and corrosion.…”

Material and dimensional properties of surface-bonded fiber Bragg gratings (FBGs) can distort strain measurement, thereby lowering the measurement accuracy. To accurately assess measurement precision and correct obtained strain, a new model, considering reinforcement effects on adhesive and measured object, is proposed in this study, which is verified to be accurate enough by the numerical method. Meanwhile, a theoretical strain correction factor is obtained, which is demonstrated to be significantly sensitive to recoating material and bonding length, as suggested by numerical and experimental results. It is also concluded that a short grating length as well as a thin but large-area (preferably covering the whole FBG) adhesive can enhance the correction precision.
