“…The SHM techniques not only can be applied to detecting damage but also evaluating curing process of composite when they were utilized in production stage. In the former investigations, both the fiber Bragg grating [12][13][14][15][16][17][18] and guided wave (GW) [19][20][21][22][23][24][25][26] methods have been adopted to study the curing monitoring issues. However, there are obvious limitations when the optical fiber sensors and GW methods are used for curing process monitoring.…”

As one of cost-effective maintenance methods, bonded composite patch repair has been receiving more and more attention in the engineering community since past decades. However, realizing real-time monitoring for curing process of bonded repair patch is difficult for most current techniques. In our work, a method based on electromechanical impedance and system parameters evaluation for structural health monitoring issues was developed, which could implement the online monitoring throughout whole curing process. Compared with the dynamic thermomechanical analysis results, the experiment data matches well. It demonstrates that the proposed approach can effectively monitor the curing process of composite repair patch at a constant temperature of 120 °C. Hence, the presented approach in this paper is expected to be a novel, robust, and real-time monitoring method for structural maintenance with the composite patch.

“…Numerous biological processes involve strain variations on the microscale, e.g., cell migration and differentiation, − wound healing, − and tumor progression . In order to study biomechanics and develop intelligent composite materials and advanced medical devices, , real-time multipoint sensors with micron-level resolution can be integrated into high-value materials. One interesting example is the shape-sensing surgical catheter, which enables surgeons to easily navigate intricate anatomical pathways and perform minimally invasive surgeries in targeted areas. − …”

Photonic mechanical sensors offer several advantages over their electronic counterparts, including immunity to electromagnetic interference, increased sensitivity, and measurement accuracy. Exploring flexible mechanical sensors on deformable substrates provides new opportunities for strain-optical coupling operations. Nevertheless, existing flexible photonics strategies often require cumbersome signal collection and analysis with bulky setups, limiting their portability and affordability. To address these challenges, we propose a waveguide-integrated flexible mechanical sensor based on cascaded photonic crystal microcavities with inherent deformation and biaxial tensile state analysis. Leveraging the advanced multiplexing capability of the sensor, for the first time, we successfully demonstrate 2D shape reconstruction and quasi-distributed strain sensing with 110 μm spatial resolution. Our microscale mechanical sensor also exhibits exceptional sensitivity with a detected force level as low as 13.6 μN in real-time measurements. This sensing platform has potential applications in various fields, including biomedical sensing, surgical catheters, aircraft and spacecraft engineering, and robotic photonic skin development.
