Here, we propose a novel strategy integrating rotational co-extrusion with wet spinning to fabricate helical conductive fibers with exceptional strain insensitivity and temperature sensing capabilities. By dynamically controlling the nozzle rotation speed (0–100 r/min), we achieve programmable helical architectures in the conductive layer, which synergistically dissipate mechanical stress through geometric deformation and maintain conductive pathways via dynamic ion redistribution in porous structures. The resulting fibers exhibit ultra-low resistance variation (Δ<i>R</i>/<i>R</i>₀ = 3.81% at 100% strain) and outstanding stability under bending (90°), twisting (720°), and cyclic stretching (1000 cycles). Simultaneously, the embedded ionic liquid endows the fibers with high thermal sensitivity (71.78% resistance drop at 20–70 °C), enabling precise temperature monitoring even during motion. Notably, the fibers demonstrate a linear response in the physiologically critical 30–40 °C range (18.5% resistance change), outperforming existing SICFs in strain–temperature decoupling. This study not only innovatively proposes a scalable process that integrates helical structure programming, material compounding, and fiber forming into a single operation but also extends the application of rotational co-extrusion technology to the field of wet spinning. It provides novel insights for multifunctional conductive fibers in areas such as wearable health monitoring and soft robotics sensing.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"8 3","pages":"1273 - 1288"},"PeriodicalIF":21.3,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147734848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, the tactile-sensing encryption device can convert user-operated physical signals (e.g., pressure) into electrical signals, forming specific password sequences to achieve personalized information encryption. However, the above devices employ non-biometric encryption technology, facing the bottleneck of encryption sequences being easily cracked, which severely compromises the information security of users. Herein, inspired by the signaling transmission of biological synapse, a biometric tactile-sensing encrypted nerve fiber (BTENF) is fabricated by constructing a synapse-like coupling capacitance micro-structure at the interface between human and the BTENF. Once the finger contacts the BTENF, this capacitance structure can disrupt the original electrical field equilibrium of the BTENF, instantaneously triggering the sensing signal, which can be called the touch current (&lt; 10 ms). Notably, the strength of the current is closely related to the local enrichment capability of free ions within the human body, exhibiting biological specificity. In addition, similar to biological synapses, the BTENF also possesses spatiotemporal dynamic dependency and stimulation-strength perceptual properties. Based on this, by integrating a neural network, a visualization closed-loop biometric tactile encryption system has been fabricated, which can precisely analyze the biometric feature signals and physical feature signals of the touch current triggered by different users (accuracy &gt; 99.24%). As a proof of concept, a smart home with a biometric-level security encryption function is proposed, which can eliminate the risk of password leakage. Therefore, we believe that the BTENF provides a novel technological pathway for the smart home encryption field.</p></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"8 4","pages":"1414 - 1426"},"PeriodicalIF":22.6,"publicationDate":"2026-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148268552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report a universal ion-induced alignment and locking strategy that programs disordered dECM proteins into strong, continuous, and bioactive fibers, through the formation of an orientated structure and increased crystallization and aggregation of polymer chains. The resulting dECM fibers exhibit superior mechanical performances, including high strength (15 MPa), toughness (171 MJ/m³), modulus (13 MPa), and excellent immunocompatibility, outperforming many reported natural and synthetic fibers. We demonstrate the practical utility of these fibers as high-performance surgical sutures that promote wound healing and as soft, flexible, and insulating core–shell neural electrodes for effective wireless nerve stimulation and signal recording. Moreover, this strategy proves effective across dECMs from various tissues and enhances the strength of other synthetic fibers such as polyvinyl alcohol, alginate, and gelatin by orders of magnitude.

A design-to-application framework is used to organize the field, connecting feedstock selection and pretreatment to precursor formulation, spinnability, and multiscale structure formation. Two complementary fiber-spinning strategies are examined: colloidal routes, in which nanocellulose and derivative slurries are assembled into percolated networks, and solution routes, in which cellulose is dissolved in greener solvent systems, and regeneration, drawing, and crystallinity are precisely regulated. Across both approaches, quantitative structural determinants governing processability and performance are distilled, including degree of polymerization, crystallinity, aspect ratio, surface charge, relaxation time, and coagulation kinetics. The roles of flow fields, gelation and phase separation, and post-treatments in dictating orientation, porosity, interfacial coupling, and defect populations are further synthesized. These structure levers define the pathways for mechanical robustness, electrical and ionic transport, thermal conduction and radiation, and responsive behavior. Recent progress is consolidated for electromagnetic interference shielding textiles, flexible and wearable sensors, energy storage and conversion fibers, thermal management and radiative cooling, and biomedical platforms, with emphasis on property targets, device integration, and durability under realistic operating conditions. Finally, key priorities are identified, including standardized spinnability metrics and in-line diagnostics, achieving solvent and reagent circularity, developing data-guided process maps for scale-up, and implementing end-of-life strategies that keep cellulose within a closed-loop system. Collectively, these perspectives are intended to accelerate the transition of spun cellulosic fibers from sustainable alternatives to first-choice materials for next-generation functional textiles and devices.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"8 3","pages":"843 - 879"},"PeriodicalIF":21.3,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147735002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methacrylated collagen (ColMA) was first crosslinked with dithiothreitol (DTT) through a visible light-induced thiol-ene reaction, forming an amorphous gel within seconds (Stage Ⅰ). Upon physiological incubation, the system spontaneously reconstructed into a fibrous matrix (Stage Ⅱ) with tunable mechanics and redox activity.
