“…[ 49 ] Another recent work at the Centre Européen des Textiles Innovants (CETI) in France applied MS technology to develop tricomponent piezoelectric multifilament yarns using polyethylene high‐density (PEHD), polyamide (PA 12), and high β‐phase content (97%) piezoelectric PVDF fibers. [ 50 ] Meanwhile, in Germany, an investigation is underway to conceptualize a capacitive multicomponent monofilament structure using MS for a novel textile actuator and sensor networks. [ 51 ] Nilsson et al used melt‐spun PVDF fibers to fabricate a textile sensor (voltage–strain ratio of 80 VN −1 ) to register human heartbeat and respiration.…”

The digitization of textiles (textronics) has created new opportunities for integration with conformable sensors to enable unobtrusive, noninvasive, and continuous decoding of vital body signals. This article provides an in‐depth review of the materials and fabrication methodologies used for textronic sensors per their form‐factor in the textile manufacturing process chain—fiber, yarn, fabric, and apparel. Next, it analyzes the performance characterization techniques currently used for these sensors and highlights the needs for standardized test methods in the following aspects: biocompatibility, thermal and tactile comfort, aging, and operation of the biomedical sensing modality at standard human stretch. It also identifies the significance of pretreatment and conditioning reporting of the textile form‐factors based on their impact on mechanical and electric performance of the textronic sensor. The study concludes by recommending a universal testing roadmap for textronic sensors which is expected to veritably complement the work of different standardization committees, including CEN TC‐248/WG‐31, IEC TC‐124, ASTM D13.50, and AATCC RA111.

“…[9][10][11] Melt spinning produces yarns with excellent functionality and a wide range of applications, and is a relatively simple process with high production efficiency. 12 However, melt spinning has a stringent temperature requirement: excessive melt temperature will lead to polymer degradation and bubble formation; if the temperature is too low, the melt viscosity will be too high. Both prevent the spinning process from working properly.…”

Piezoelectric textiles have earned widespread acceptance in the application of wearable sensors owing to the stabilized energy conversion properties, high sensitivities and steady mechanical properties. In this study, silver-coated nylon yarns are used as a core with poly(vinylidene fluoride) nanofibers as a wrap material, forming piezoelectric wrapped yarns. The effect of spinning process parameters on the structure and crystallinity of the piezoelectric yarn is investigated through studying the mechanical properties, ⊎-phase ratio, crystallinity and piezoelectric properties. The results indicate that the crystallinity of the wrapped yarn reaches 49.57% in this experiment, and when used for piezoelectricity, the piezoelectric voltage constant can reach up to 0.4323 mV m N −1 . The wrapped yarns possess good softness and structural advantages of the sensing layer and thus show a great variety of application potential, such as in wearable and flexible sensors.

“…[48,49] However, the tricomponent melt extrusion (TME) process, in which three polymers are extruded simultaneously to form a single fiber, is rather uncommon. [53,54] TME has been used to fabricate fibers with unique optical properties, [53] and for energy harvest- Representative cross-sectional image of TME fibers as spun e) before removal of the sacrificial polymer, and f) after removal of the sacrificial polymer ing applications, [54] but has not yet been investigated for fabricating fiber-based sensors.…”

Textile‐based flexible sensors are key to the development of personal wearable electronic devices and systems for a wide range of applications including physiological monitoring, communication, and entertainment. Textiles, for their many desirable characteristics and use, offer a natural interface between electronics and the human body. A wide range of fabrication techniques have been explored for textile‐based sensors; however, most are not compatible or readily adaptable to textile manufacturing processes. Here, a practical and scalable method of producing textile‐based sensory fibers using a common manufacturing technique, melt extrusion, is proposed. An overview of the fabrication method as well as the mechanical and electrical properties of the fibers is presented. Subsequently, the fibers’ ability to sense changes in pressure is studied in detail using assembled fibers. Methods to improve the sensor performance by altering the geometry of the fiber assembly are also presented. As a proof‐of‐concept demonstration, the fibers are woven into a pressure‐sensing fabric mat consisting of 64 sensing elements. The woven substrate can detect the location and level of pressure, thereby illustrating the fibers' potential use as sensors in textile structures.
