“…The feasibility of fabricating SMART layers into 3D shapes, their surface mounting, and implantation within composite and integration into a filament-wound structure has been investigated [ 63 , 64 ]. Several studies have been conducted to evaluate the effects of loading, temperature, moisture, and aggressive chemical environments on SMART technology [ 62 , 63 , 64 , 65 , 66 , 67 , 68 ]. The SMART layer is fabricated based on the flexible printed circuit technique.…”

Recently, there has been a growing interest in deploying smart materials as sensing components of structural health monitoring systems. In this arena, piezoelectric materials offer great promise for researchers to rapidly expand their many potential applications. The main goal of this study is to review the state-of-the-art piezoelectric-based sensing techniques that are currently used in the structural health monitoring area. These techniques range from piezoelectric electromechanical impedance and ultrasonic Lamb wave methods to a class of cutting-edge self-powered sensing systems. We present the principle of the piezoelectric effect and the underlying mechanisms used by the piezoelectric sensing methods to detect the structural response. Furthermore, the pros and cons of the current methodologies are discussed. In the end, we envision a role of the piezoelectric-based techniques in developing the next-generation self-monitoring and self-powering health monitoring systems.

“…In particular, the energy consumption, weight, and space required for the circuitry involved in the actuation and processing of the signals connected to the active SHM is still a challenge to allow for a permanently installed, continuous real-time monitoring of the involved structures [23][24][25]. Conversely, if the target of the SHM system is the impact detection, such electronic equipment can be greatly simplified because the actuation circuitry is no longer required since the waves generated by the impact are exploited.…”

In this work, we report on some research developments to support the upscaling of nondestructive evaluation and structural health monitoring (SHM) approaches, mainly based on ultrasonic guided waves, for aeronautical applications. In particular, first a spiral-shaped piezoelectric sensor sensitive to the wave direction of arrival (WDA) of guided waves propagating in plate-like structures is described. Next, a miniaturized sensor node capable to perform locally signal processing algorithms, as those developed for the spiral sensors, is presented. The sensor node weights 4 g, measures approximately 20 × 24 mm, is characterized by a low power consumption and exploiting a data-over-power (DoP) network communication reduces to a minimum the need for cabling. At such the spiral sensors and sensor node result to be suitable for the upscaling of SHM approaches devoted to locate impacts as well as delaminations in aircrafts fuselage and wings. Next, impact and/or damage coordinates are passed to an augmented reality (AR) framework that allows the NDT inspector, if equipped with a proper visual device, to see in real time directly on the structure the position of the impact/damage. In the end, by guiding the technician directly to spots potentially damaged this could speed up the NDT visual inspection phase as well as it should reduce the possibility that damages would go undetected. Applications of the above methodologies/technologies for impact localization on an aluminum plate are presented.

In order to take full advantages of composites and enable future composite structures to operate at their physical limits rather than limits predetermined from computational design assumptions and safety factors, there is a need to develop an embeddable sensing system to allow a structure to "feel" and "think" its structural state. In this paper, the concept of multi-modal sensing capabilities using a network of multifunctional sensors integrated with a structure has been developed. Utilizing this revolutionary concept, future structures can be designed and manufactured to provide multiple modes of information that when synthesized together can provide capabilities for intelligent sensing, environmental adaptation and multi-functionality. To demonstrate the feasibility of multi-modal sensing capabilities with built-in sensor network, one single type of piezoelectric sensor was selected to perform the measurements of dynamic strain, temperature, damage detection and impact monitoring. The uniqueness of the sensing system includes (1) Flexible, multifunctional sensor networks for integration with any type of composite structural component, (2) Scalable sensor network for monitoring of a large composite structure, (3) Reduced number of connecting wires for sensors, (4) Hybrid diagnostics with multiple sensing capabilities, (5) Sensor network self-diagnostics and self-repair for damaged sensor system.
