“…Regarding the fabrication, the proposed sensing structure integrates SMF with a sensitive PI tube, making it easy to achieve mass production. Compared to the specialty optical fiber, for example the SMF for fabrics to enhance the acoustic pressure sensitivity of the fiber [1], the feature of the current sensor employs a Fabry-Perot interferometer as a sensitivity enhancement structure. As a further improvement, it is possible to replace the SMF using specialty optical fiber to increase the sensing performance of the fiber.…”

“…In addition to the conventional single mode fiber (SMF) designed for the optical communication, various specialty optical fibers have been demonstrated as well. Those fibers employ novel structure and materials to achieve microstructured fibers [1] or multimaterial fibers [2][3][4], providing more opportunities and feasibility to develop high performance sensors.…”

The temperature and pressure of seawater are of great importance to investigate the environmental evolution for the research of ocean science. With this regard, we proposed and experimentally demonstrated a seawater temperature and pressure sensor realized by a polyimide (PI) tube-based Fabry-Perot interferometer (FPI) together with a fiber Bragg grating (FBG). Benefiting from the higher thermo-optical coefficient and larger elasticity of polymer than the fused silica fiber, the sensitivity of the sensor is largely improved. The FBG is used to compensate the cross effect of the temperature. The measured temperature and pressure sensitivities of the sensor are 18.910 nm/°C and −35.605 nm/MPa, respectively. Furthermore, the temperature and pressure information measured by the sensor can be achieved simultaneously using the sensitivity matrix method. In addition, the proposed sensor has advantages of easy fabrication, compact size, as well as capability of multiplexing and long-distance measurement, making it competitive and promising during the marine monitoring.

“…Moreover, the advent of nano-bio sensors may offer advanced sensing solutions for clinicians [ 23 ]. As current FSR sensors can be cumbersome, fiber and textile-based sensors may soon offer unobtrusive wearable sensors for prosthetics [ 24 , 25 , 26 , 27 ]. Objective instruments such as the FSR offer a valid means to measure prosthetic socket interventions [ 28 ].…”

(1) Background: A sustainable casting system that combines the use of a polystyrene bag, a prosthetic liner and a vacuum system was developed to reduce fabrication time while maintaining comfort for the trans-tibial prosthesis user. (2) Methods: Eight prosthetists (28.7 ± 8.25 years old) fit ten trans-tibial prosthesis wearers (46 ± 12.4 years old) with two types of total surface bearing (TSB) prostheses; a polystyrene bead (PS) prosthesis and a plaster of paris (POP) prosthesis. Duration of casting and combined mean peak pressure was measured at six locations on the residual limb using Force Sensing Resistors (FSR). A pressure uniformity score (%) was determined. Socket Comfort Scale (SCS) was also measured. (3) Results: Duration of casting for the POP method was 64.8 ± 9.53 min and 7.8 ± 2 min for the PS method, (p = 0.006). Pressure uniformity in the POP prosthesis was 79.3 ± 6.54 and 81.7 ± 5.83 in the PS prosthesis (p = 0.027). SCS in both prosthesis types were equivalent. (4) Conclusion: A rapid fit PS prosthesis was developed, with significantly shorter duration than the traditional POP method. Socket pressure uniformity was confirmed and improved in the PS method. Socket comfort was equal between the two prothesis types.

Sustainable, clean, random energy resources from the environment, like that from ubiquitous human biomechanical movements, are highly desirable for the information era. Such biomechanical energy can be captured via textile triboelectric nanogenerators (TENGs). However, realizing a textile TENG that has a self‐driven working mode, dynamic pattern designability, high electrical performance, mechanical robustness, and industrialized fabrication is challenging because of the difficulty in fancy‐yarn structure manipulation. Here, for the first time, a 3D braided stretchable hierarchical interlocking fancy‐yarn TENG (3D HIFY‐TENG) with deoxyribonucleic acid‐like double‐wing spiral structure is industrially exploited for multifunctional energy harvesting modes and self‐powered biomechanical sensing. The 3D HIFY‐TENG can generate self‐driven triboelectrical outputs without relying on other objects by body movements. It shows a mechanical robustness (6.9 cN dtex−1), excellent stretchability (>350%), weavability, washability and human‐body comfort. Moreover, geometric and mechanical behavior of the 3D HIFY‐TENG are systematically investigated theoretically and experimentally. Further, multifunctional 3D HIFY‐TENG fabrics are explored, which can not only harvest biomechanical energy and monitor body movement, but exhibit a unique adjustable pore effect, providing potential for dynamic electronic textile pattern design. In addition, a smart fitness system is developed for exercise management of real‐time exercise detection, frequency analysis, and self‐powered posture correction alarms.
