Highly Durable and Fast Response Fabric Strain Sensor for Movement Monitoring Under Extreme Conditions

The exploration of smart electronic textiles is a common goal to improve people’s quality of life.However,current smart e-textiles still face challenges such as being prone to failure under humid or cold conditions,lack of washing durability and chemical fragility.Herein,a multifunctional strain sensor with a negative resistance change was developed based on the excellent elasticity of knitted fabrics.A reduced graphene oxide(rGO)conductive fabric was first obtained by electrostatic self-assembly of chitosan(CS).Then a strain sensor was prepared using a dip-coating process to adsorb nanoscale silica dioxide and poly(dimethylsiloxane)(PDMS).A broad working range of 60%,a fast response time(22 ms)and stable cycling durability over 4000 cycles were simultaneously achieved using the prepared sensor.Furthermore,the sensor showed excel-lent superhydrophobicity,photothermal effects and UV protection,as graphene,silica and PDMS acted in synergy.This multifunctional sensor could be mounted on human joints to perform tasks,including activity monitoring,medical rehabili-tation evaluation and gesture recognition,due to its superior electromechanical capabilities.Based on its multiple superior properties,this sensor could be used as winter sportswear for athletes to track their actions without being impacted by water and as a warmer to ensure the wearer's comfort.

All‑Fiber Integrated Thermoelectrically Powered Physiological Monitoring Biosensor

Advanced fabric electronics for long-term personal physiological monitoring,with a self-sufficient energy source,high integrity,sensitivity,wearing comfort,and homogeneous components are urgently desired.Instead of assembling a self-powered biosensor,comprising a variety of materials with different levels of hardness,and supplementing with a booster or energy storage device,herein,an all-fiber integrated thermoelectrically powered physiological monitoring device(FPMD),is proposed and evaluated for production at an industrial scale.For the first time,an organic electrochemical transistor(OECT)biosensor is enabled by thermoelectric fabrics(TEFs)adaptively,sustainably and steadily without any additional accessories.Moreover,both the OECT and TEFs are constructed using a cotton/poly(3,4-ethylenedioxythiophene):poly(styrenesulfon ate)/dimethylsulfoxide/(3-glycidyloxypropyl)trimethoxysilane(PDG)yarn,which is lightweight,robust(90°bending for 1000 cycles)and sweat-resistant(ΔR/R0=1.9%).A small temperature gradient(ΔT=2.2 K)between the environment and the human body can drive the high-gain OECT(71.08 mS)with high fidelity,and a good signal to noise ratio.For practical applications,the on-body FPMD produced an enduring and steady output signal and demonstrated a linear monitoring region(sensitivity of 30.4 NCR(normalized current response)/dec,10 nM~50µM)for glucose in artificial sweat with reliable performance regarding anti-interference and reproducibility.This device can be expanded to the monitoring of various bio-markers and provides a new strategy for constructing wearable,comfortable,highly integrated and self-powered biosensors.

Ta_(3)N_(5)/CdS Core–Shell S‑scheme Heterojunction Nanofibers for Efficient Photocatalytic Removal of Antibiotic Tetracycline and Cr(VI):Performance and Mechanism Insights

Ta_(3)N_(5)/CdS core–shell S-scheme heterojunction nanofibers are fabricated by in situ growing CdS nanodots on Ta_(3)N_(5) nanofib-ers via a simple wet-chemical method.These Ta_(3)N_(5)/CdS nanofibers not only affords superior photocatalytic tetracycline degradation and mineralization performance,but also cause an efficient photocatalytic Cr(VI)reduction performance.The creation of favorable core–shell fiber-shaped S-scheme hetero-structure with tightly contacted interface and the maximum interface contact area promises the effective photo-carrier disintegration and the optimal photo-redox capacity synchronously,thus leading to the preeminent photo-redox ability.Some critical environmental factors on the photo-behavior of Ta_(3)N_(5)/CdS are also evaluated in view of the complexity of the authentic aquatic environment.The degradation products of tetracycline were confirmed by HPLC–MS analyses.Furthermore,the effective decline in eco-toxicity of TC intermediates is confirmed by QSAR calculation.This work provides cutting-edge guidelines for the design of high-performance Ta_(3)N_(5)-based S-scheme heterojunction nanofibers for environment restoration.

Hyperelastic Graphene Aerogels Reinforced by In‑suit Welding Polyimide Nano Fiber with Leaf Skeleton Structure and Adjustable Thermal Conductivity for Morphology and Temperature Sensing

Graphene-aerogel-based flexible sensors have heat tolerances and electric-resistance sensitivities superior to those of polymer-based sensors.However,graphene sheets are prone to slips under repeated compression due to inadequate chemical con-nections.In addition,the heat-transfer performance of existing compression strain sensors under stress is unclear and lacks research,making it difficult to perform real-temperature detections.To address these issues,a hyperelastic polyimide fiber/graphene aerogel(PINF/GA)with a three-dimensional interconnected structure was fabricated by simple one-pot compound-ing and in-situ welding methods.The welding of fiber lap joints promotes in-suit formation of three-dimensional crosslinked networks of polyimide fibers,which can effectively avoid slidings between fibers to form reinforced ribs,preventing graphene from damage during compression.In particular,the inner core of the fiber maintains its macromolecular chain structure and toughness during welding.Thus,PINF/GA has good structural stabilities under a large strain compression(99%).Moreover,the thermal and electrical conductivities of PINF/GA could not only change with various stresses and strains but also keep the change steady at specific stresses and strains,with its thermal-conductivity change ratio reaching up to 9.8.Hyperelastic PINF/GA,with dynamically stable thermal and electrical conductivity,as well as high heat tolerance,shows broad applica-tion prospects as sensors in detecting the shapes and temperatures of unknown objects in extreme environments.

Okra‑Like Multichannel TiO@NC Fibers Membrane with Spatial and Chemical Restriction on Shuttle‑Effect for Lithium–Sulfur Batteries

It is especially important to coordinately design the structure and composition of the host in lithium–sulfur batteries(LSBs)for improving its physicochemical adsorption and conversion of lithium polysulfide,which can alleviate the harmful shuttle effect.Herein,a self-supporting multichannel nitrogen-doped carbon fibers membrane embedded with TiO nanoparticles(TiO@NC)was constructed as the electrode for LSBs.The inner channels and the embedded TiO nanoparticles offer spatial confinement and chemical binding for polysulfides,respectively.Moreover,the TiO nanoparticles have abundant oxygen vacancies that promote the conversion of polysulfides.In addition,the nitrogen-doped carbon skeleton can not only serve as highly conductive transportation paths for electrons,but also integrate with the inner channels to sustain the morphology and bear volume expansion during cycling processes.Therefore,the fabricated self-supporting quadruple-channel TiO@NC ultrathin fibers electrode exhibits a high initial specific capacity of 1342.8 mAh g^(-1)at 0.5 C and high-rate capability of 505.8 mAh g^(-1)at 4.0 C.In addition,it maintains 696.0 mAh g^(-1)over 500 cycles with only 0.059%capacity decay per cycle at the high current density of 2.0 C.The multichannel configuration combined with TiO nanoparticles provides a synergetic design strategy for fabricating high-performance electrodes in LSBs.

Defect Engineering in g‑C_(3)N_(4)Quantum‑Dot‑Modified TiO_(2)Nanofiber:Uncovering Novel Mechanisms for the Degradation of Tetracycline in Coexistence with Cu^(2+)

Herein,g-C_(3)N_(4)quantum-dot-modified TiO_(2)nanofibers were fabricated and used as an efficient photocatalyst for the investigation of the influence of Cu^(2+)and the interaction mechanism between Cu^(2+)and surface defects in tetracycline degradation.Results showed that the effect of Cu^(2+)switched from promoting to inhibiting the tetracycline degradation as the amount of Cu^(2+)accumulated on the catalyst surface increased.The introduction of surface defects can prevent the inhibiting effect of Cu^(2+),resulting in the more complete degradation of tetracycline in contrast to the non-defective sample.Theoretical calculations further revealed that the defects can be used to tune the conduction band of the composite,inducing the reduction reaction of Cu^(2+)and inhibiting the accumulation of Cu on the surface of catalysts.Moreover,the Cu introduced to the catalyst surface provided new active sites,thereby promoting photocatalytic degradation.These findings provide new insights into the design of advanced fiber materials for water purification in complex environments.

Chlorine‑Rich Substitution Enabled 2D3D Hybrid Perovskites for High Efficiency and Stability in Sn‑Based Fiber‑Shaped Perovskite Solar Cells

Despite the impressive power conversion efficiency(PCE)beyond 25.5%,perovskite solar cells,especially the Sn-based variants,are poorly stable under normal operating conditions compared with the market-dominant silicon solar cells that can last for over 25 years.2D3D hybrid perovskite materials are one of the best options to overcome the instability chal-lenge without compromising efficiency.Indeed,a record performance of 1 year was reported in Pb-based 2D3D planar per-ovskite devices.However,the reaction between 2 and 3D perovskite molecules requires high temperatures(-300°C)and increased reaction time(-24 h)to achieve high-quality 2D3D hybrid perovskites.Herein,we base on the ability of chlorine to displace iodine from its ionic compounds in solutions to utilize chloride ions as catalysts for speeding up the reaction between iodine-based 2D and 3D perovskite molecules.The approach reduces the reaction time to-20 min and the reaction temperature to-100°C with the formation of high-quality 2D3D hybrid perovskites,free from pure 2D traces.Integrating the synthesized 2D3D hybrid perovskite material with 50%chlorine doping in a fiber-shaped solar cell architecture yielded the highest reported PCE of 11.96%in Sn-based fiber-shaped perovskite solar cells.The unencapsulated and encapsulated fiber-shaped solar cells could maintain 75%and 95.5%of their original PCE,respectively,after 3 months under room light and relative humidity of 35–40%,revealing the champion stability in Sn-based perovskite solar devices.The solar yarn also demonstrated constant energy output under changing light incident angles(0–180°).

Performance analysis is an important tool for gymnasts and coaches to assess the techniques,strengths,and weaknesses of rhythmic gymnasts during training.To have an accurate insight about the motion and postures can help the optimization of their performance and offer personalized suggestions.However,there are three primary limitations of traditional perfor-mance analysis systems applied in rhythmic gymnastics:(1)Inability to quantify anthropometric data in an imperceptible way,(2)labor-intensive nature of data labeling and analysis,and(3)lack of monitoring of all-round and multi-dimensional perspectives of the target.Thus,an advanced performance analysis system for rhythmic gymnastics is proposed in this paper,powered by intelligent fabric.The system uses intelligent fabric to detect the physiological and anthropometric data of the gymnasts.After a variety of data are collected,the analysis component is implemented by artificial intelligence techniques resulting in behavior recognition,decision-making,and other functions assisting performance improvement.A feasible solution to implementing the analysis component is the use of the hyperdimensional computing technique.In addition,four typical applications are presented to improve training performance.Powered by intelligent fabric,the proposed advanced performance analysis system exhibits the potential to promote innovative technologies for improving training and competi-tive performance,prolonging athletic careers,as well as reducing sports injuries.

Vascular Endothelial Growth Factor‑Recruiting Nanofiber Bandages Promote Multifunctional Skin Regeneration via Improved Angiogenesis and Immunomodulation

Tissue injury leads to gradients of chemoattractants,which drive multiple processes for tissue repair,including the inflam-matory response as well as endogenous cell recruitment.However,a limited time window for the gradients of chemoattract-ants as well as their poor stability at the injury site may not translate into healthy tissue repair.Consequently,intelligent multifunctional scaffolds with the capability to stabilize injury-induced cytokines and chemokines hold great promise for tissue repair.Vascular endothelial growth factor(VEGF)plays a significant role in wound healing by promoting angiogen-esis.The overarching objective of this research was to develop intelligent multifunctional scaffolds with the capability to endogenously recruit VEGF and promote wound healing via angiogenic and immunomodulatory dual functions.Prominin-1-derived peptide(PR1P)was encapsulated into electrospun poly(L-lactide-coglycolide)/gelatin(P/G)-based bandages.The sustained release of PR1P recruited VEGF in situ,thereby stabilizing the protein concentration peak in vivo and affording a reparative microenvironment with an adequate angiogenic ability at the wound site.Meanwhile,PR1P-recruited VEGF-induced macrophage reprogramming towards M2-like phenotypes further conferred immunomodulatory functions to the bandages.These dual functions of proangiogenesis and immunomodulation formed a cascade amplification,which regulated matrix metalloproteinases(MMP-9)as well as inflammatory factors(nuclear factor(NF)-κb,tumor necrosis factor(TNF)-α)in the wound microenvironment via the VEGF/macrophages/microenvironment axis.Consequently,the bandages realized multifunctional regeneration in splinted excisional wounds in rats,with or without diabetes,affording a higher skin append-age neogenesis,sensory function,and collagen remodeling.Conclusively,our approach encompassing in situ recruitment of VEGF at the injury site with the capability to promote immunomodulation-mediated tissue repair affords a promising avenue for scarless wound regeneration,which may also have implications for other tissue engineering disciplines.

Bioinspired Stable Single‑Layer Janus Fabric with Directional Water/Moisture Transport Property for Integrated Personal Cooling Management

Extensive progress has been achieved regarding Janus fabric for directional water transport due to its excellent and feasible personal cooling management ability,which has great significance for energy conservation,pollution reduction,and human health.However,existing Janus asymmetric multilayer fabrics for directional water transport are still limited by their com-plicated syntheses and poor stabilities.Inspired by the compositionally graded architecture of leaf cuticles,we propose a single-layer Janus personal cooling management fabric(JPCMF)via a one-step electrospinning method.The JPCMF shows not only great directional bulk water transport ability but also asymmetry moisture(water vapor)transport ability with a high asymmetry factor(1.49),water vapor transmission value(18.5 kg^(-1) m-2 D-1),and water evaporation rate(0.735 g h^(-1)).Importantly,the JPCMF exhibits outstanding durability and stability thanks to a novel electrostatic adsorption-assisted self-adhesion strategy for resisting abrasion,peeling and pulling.With these characteristics,the JPCMF can achieve a 4.0°C personal cooling management effect,better than taht of cotton fabric,on wet skin.The good biocompatibility and nontoxic-ity also endow the JPCMF with the potential to be a self-pumping dressing.Our strategy should facilitate a new method for developing next-generation intelligent multifunctional fabrics.

Skin regeneration is a matter of high concern since many individuals suffer from skin damage.To date,the concept of protein-based artificial skin scaffolds have been successfully applied and proven in skin regeneration.However,realizing a skin tissue scaffold with a skin-like extracellular matrix(ECM)that combines low price,good biocompatibility,excellent antibacterial properties,good cell adhesion,and strong mechanical properties is still a major challenge.In this study,inexpensive silk sericin(SS)protein-based artificial skin nanofiber scaffolds(NFSs)with excellent biological activity,no immune rejection,and high mechanical strength were fabricated via microfluidic blow-spinning(MBS).In particular,the as-prepared NFS was transformed from a random coil structure to aβ-sheet structure by using the MBS in high-speed shear chips to improve its stability and mechanical strength.Additionally,through in vitro and in vivo studies,it was shown that SS protein-based artificial skin NFSs possessed excellent antibacterial effects and degradability properties,as well as accelerated tissue granu-lation growth,effectively promoting full skin wound healing and skin regeneration for medical problems worldwide.Thus,this skin ECM-inspired NFS offers new perspectives for accelerating wound healing and tissue regeneration and provides potential applications for clinical medicine.

Atmospheric moisture exploitation is emerging as a promising alternative to relieve the shortage of freshwater and energy.Efforts to exploit hygroscopic materials featuring flexibility,programmability,and accessibility are crucial to portable and adaptable devices.However,current two-dimensional(2D)or three-dimensional(3D)-based hygroscopic materials are dif-ficult to adapt to diverse irregular surfaces and meet breathability,which severely hinders their wide applications in wearable and programmable devices.Herein,hygroscopic organogel fibers(HOGFs)were designed via a wet-spinning strategy.The achieved fibers were composed of the hydrophilic polymeric network,hygroscopic solvent,and photothermal/antibacterial Ag nanoparticles(AgNPs),enabling hygroscopic capacity,photothermal conversion,and antibacterial.Owing to the good knittable feature,the HOGFs can be readily woven to adjusted 2D textiles to function as an efficient self-sustained solar evaporator of 4-layer woven HOGF device with a saturated moisture capacity of 1.63 kg m^(-2) and water-releasing rate of 1.46 kg m^(-2) h^(-1).Furthermore,the 2D textile can be applied as a wearable dehumidification device to efficiently remove the evaporative moisture from human skin to maintain a comfortable environment.It can reduce the humidity from 90 to 33.4%within 12.5 min.In addition,the introduction of AgNPs can also endow the HOGFs with antibacterial features,demonstrat-ing significant potential in personal healthcare.

Temperature‑Gated Light‑Guiding Hydrogel Fiber for Thermoregulation During Optogenetic Neuromodulation

With the rise of optogenetic manipulation of neurons,the effects of optogenetic heating on temperature-sensitive physi-ological processes,and the damage to surrounding tissues have been neglected.This manuscript reports the fabrication of a highly temperature-sensitive semi-interpenetrating optical hydrogel fiber(TSOHF)using the integrated dynamic wet-spinning technique.TSOHF exhibits a structural tunable diameter,clear core/sheath structure,tunable temperature-sensitivity,excellent light propagation property(0.35 dB cm^(-1),650 nm laser light),and good biocompatibility(including tissue-like Young’s modulus,stable dimensional stability,and low cytotoxicity).Based on these properties,a potential application of optogenetic regulation of neural tissue(hypoglossal nerve),with controllable temperature using TSOHF was designed and performed.Further,this work provides new insight into molecular design and a practical approach to continually manufacture a temperature-sensitive hydrogel optical fiber for applications in intelligent photomedicine.

Water Responsive Fabrics with Artificial Leaf Stomata

Due to fiber swelling,textile fabrics containing hygroscopic fibers tend to decrease pore size under wet or increasing humid-ity and moisture conditions,the reverse being true.Nevertheless,for personal thermal regulation and comfort,the opposite is desirable,namely,increasing the fabric pore size under increasing humid and sweating conditions for enhanced ventila-tion and cooling,and a decreased pore size under cold and dry conditions for heat retention.This paper describes a novel approach to create such an unconventional fabric by emulating the structure of the plant leaf stomata by designing a water responsive polymer system in which the fabric pores increase in size when wet and decrease in size when dry.The new fabric increases its moisture permeability over 50%under wet conditions.Such a water responsive fabric can find various applications including smart functional clothing and sportswear.

Sulfur Vacancies Tune the Charge Distribution of NiCo_(2)S_(4) for Boosting the Energy Density of Stretchable Yarn‑Based Zn Ion Batteries

Yarn-based batteries with the dual functions of wearable and energy storage have demonstrated promising potential in wearable energy textiles.However,it is still an urgent problem to construct efficient and flexible electrodes while optimize the configuration of yarn-based batteries to maintain excellent electrochemical performance under different mechanical deformations.Herein,NiCo_(2)S_(4-x) nanotube arrays with tunable S-vacancies are constructed on carbon yarn(CY)(NiCo_(2)S_(4-x)@CY)by a facile hydrothermal strategy.The aqueous zinc-ion batteries(ZIBs)with NiCo_(2)S_(4-x)@CY as cathodes exhibit exceptional discharge capacity(271.7 mAh g^(-1))and outstanding rate performance(70.9%capacity retention at 5 A g^(-1)),and reveal a maximum power density of 6,059.5 W kg^(-1) and a maximum energy density of 432.2 Wh kg^(-1).It is worth noting that the tunable S-vacancies promote the surface reconfiguration and phase transitions of NiCo_(2)S_(4-x),thereby enhancing the conductivity and charge storage kinetics.The high reactivity and cycling stability of NiCo_(2)S_(4-x)@CY can be related to the discharge products of S-doped NiO and CoO.Furthermore,flexible stretchable yarn-based ZIBs with wrapped yarn structures are constructed and exhibit excellent tensile stability and durability under a variety of mechanical deformations.As a proof of concept,the ZIBs integrated into the fabric show excellent electrochemical performance even in response to simultaneous stretching and bending mechanical deformations.The proposed strategy provides novel inspiration for the development of highly efficient and economical yarn-based ZIBs and wearable energy textiles.

Elastic Fiber‑Reinforced Silk Fibroin Scaffold with A Double‑Crosslinking Network for Human Ear‑Shaped Cartilage Regeneration

Tissue engineering provides a promising approach for regenerative medicine.The ideal engineered tissue should have the desired structure and functional properties suitable for uniform cell distribution and stable shape fidelity in the full period of in vitro culture and in vivo implantation.However,due to insufficient cell infiltration and inadequate mechanical properties,engineered tissue made from porous scaffolds may have an inconsistent cellular composition and a poor shape retainability,which seriously hinders their further clinical application.In this study,silk fibroin was integrated with silk short fibers with a physical and chemical double-crosslinking network to fabricate fiber-reinforced silk fibroin super elastic absorbent sponges(Fr-SF-SEAs).The Fr-SF-SEAs exhibited the desirable synergistic properties of a honeycomb structure,hygroscopicity and elasticity,which allowed them to undergo an unconventional cyclic compression inoculation method to significantly promote cell diffusion and achieve a uniform cell distribution at a high-density.Furthermore,the regenerated cartilage of the Fr-SF-SEAs scaffold withstood a dynamic pressure environment after subcutaneous implantation and maintained its precise original structure,ultimately achieving human-scale ear-shaped cartilage regeneration.Importantly,the SF-SEAs prepara-tion showed valuable universality in combining chemicals with other bioactive materials or drugs with reactive groups to construct microenvironment bionic scaffolds.The established novel cell inoculation method is highly versatile and can be readily applied to various cells.Based on the design concept of dual-network Fr-SF-SEAs scaffolds,homogenous and mature cartilage was successfully regenerated with precise and complicated shapes,which hopefully provides a platform strategy for tissue engineering for various cartilage defect repairs.
