“…By increasing the contents of AgNWs in the yarn, a high electrical conductivity of 5 Ω cm −1 , stretchability greater that 100% high stability over 10 000 strain cycles of 90% with negligible change in its sensitivity were realized ( Figure a). Lu et al also used AgNWs to fabricate 1D stretchable conductive yarns . They obtained higher electrical conductivities and stretching ranges by modifying the surface of AgNWs to greatly improve the compatibility with a stretchable PU matrix.…”

applications, and smart sportswear. [13][14][15][16][17] In this regard, stretchable and wearable electronic devices in the 1D form, which can be directly integrated into daily clothes without any inconsistency, are greatly promising for future wearable electronics. [18][19][20][21][22][23] In addition, the hierarchical property of the fibrous structures (fiber: a small and short piece of a strand, filament: a long strand, yarn: an intertwined 1D structure of fibers or filaments, and fabric: a flexible substance consisting of a network of yarns) makes 1D electronic devices and systems remarkably suitable for advanced wearable electronics. The 1D assemblies including the 1D electronic devices also have unique characteristics appropriate to wearable electronics such as softness, stretchability, breathability, and high tolerance to damage. [3] Stretchability, in particular, is one of the most important properties for practical wearable applications because smart clothes or textiles including such 1D electronic devices should be covered on soft and curved human body. [24] Furthermore, some parts of clothes are frequently stretched and deformed during natural movements in daily life, thereby increasing the importance of stretchability of 1D electronic devices. Although many of existing clothes have achieved certain stretchability with only rigid yarns through specific textile structures such as woven or knitted structures, the stretchability resulting from such textile structures is insufficient to cover high stretchability desired in specific applications. For example, high stretchability of textiles is highly required for sportswear in order to achieve a form-fitting property, high comfortability, and elasticity during exercise. For such purpose, various stretchable yarns such as spandex have been widely used in textile industry. These properties of textiles are also essential for various sensing applications of wearable and textile electronic, resulting that high stretchability should be achieved for the 1D electronic devices. [25,26] In addition, the high stretchability resulting from the use of stretchable conductive yarns can successfully prevent a bagging issue of smart textiles which degrades stability and reproducibility of the smart textiles. For achieving the 1D stretchable electronic devices and systems, the development of 1D stretchable electrodes such as conductive yarns or filaments with high electrical conductivity and stretchability is basically essential above other things. In this regard, recent advances toward developing various high-performance Research on wearable electronic devices that can be directly integrated into daily textiles or clothes has been explosively grown holding great potential for various practical wearable applications. These wearable electronic devices strongly demand 1D electronic devices that are light-weight, weavable, highly flexible, stretchable, and adaptable to comport to frequent deformations during usage in daily life. To this end, the development of 1D electrodes wit...

“…The AgNWs were synthesized by the typical polyol process with an average diameter of 80 nm and an average length of 20 μm, respectively (Figure (a)). The diameter and length distribution were reported in our previous work . After dispersing the AgNWs in the FA solvent for 120 h, no morphological and structural changes of the AgNWs were observed, indicating that the AgNWs were stable in FA solvent compared to that prior to dispersion (Figure (b–d)).…”

Biocompatible flexible conductive composite fibers have attracted great research interest because of multitude of their potential applications, such as wearable devices, biomedical sensors, and actuators. Herein, highly conductive and flexible silver nanowire (AgNW)/fibroin composite fibers were fabricated by using a wet‐spinning technique. The composite fiber conductivity was as high as 5670 S/cm at an AgNW concentration of 29.1 wt%. The composite fibers also exhibited high flexibilities and could be folded without losing their conductivities. Furthermore, the composite fiber fabricated with a 3× draw ratio exhibited a breaking strain of 27.3% and breaking stress of 118.1 cN/dtex. Our attempt to produce such biocompatible flexible conductive composite fibers by using sustainable regenerated silk fibroins and compatible AgNWs via wet spinning may provide a practical way for fabricating functional biocompatible fiber materials.

“…When they are subjected to mechanical deformation or environmental stimulation, their microstructure or intrinsic conductivity will change, which can be transduced into electrical signals such as resistance/capacitance changes or voltage/current generations. A variety of nanomaterials with high conductivity including carbon nanomaterials, conducting polymers, metallic nanowires, and liquid metals have been used to prepare conductive fibers for sensing devices.…”

“…However, these kinds of fiber sensors suffered from easy damage and inferior stability. Doping conductive fillers such as metal nanoparticles and nanowires into nonconductive elastomers represents a promising solution to improve the stability of the fiber strain/stress sensors . It is worth noting that a textile triboelectric nanogenerator had been made for human respiratory monitoring by loom weaving Cu‐based yarns in the conventional weaving process .…”

(2 of 25)www.advmat.de www.advancedsciencenews.com energy and then deliver it to power other electronic devices whenever we want. The existing fiber-shaped energy storage devices include the supercapacitor, [15] the lithium (Li)-ion battery, [16] the lithium-sulfur battery, [17] the lithium-air battery, [18] the zinc-air battery, [19] the aluminum-air battery, [20] the sodiumion battery, [21] the zinc-ion battery, [22] and the silver-zinc battery. [23] Among them, the supercapacitor has been reported mostly due to the easy fabrication, and lithium-ion battery has laid the foundation for the development of other fiber-shaped batteries, which are thus discussed mainly in this review. 3) Light-emitting devices have been developed for various applications such as display, illumination, and photo therapy. According to the working mechanisms, there are electroluminescence, [24] mechanoluminescence, [25] photoluminescence, [26] thermoluminescence, [27] sonoluminescence, [28] and chemiluminescence. [29] Among these, fiber-shaped electroluminescent devices have been developed extensively due to their good controllability, driven by direct current (DC) [30] or alternating current (AC) [31] electrical method, which are expounded mainly later. 4) Fibershaped sensors have found great potentials in the field of wearable medical devices for fitness monitoring and medical diagnostics especially as aging populations grow. By virtue of the 1D structure, fiber-shaped sensors can be implanted into the body with little injure or they can detect multiple signals simultaneously after integration into a tiny unit. [32] Fiber-shaped sensors generally work via physical processes on the basis of conducting fiber [33] and optical fiber, [34] and chemical processes based on chemical ligand. [35] Thereinto, fiber optic sensors have already been used in petrochemical, electric power, medical, civil engineering, etc. The detailed discussions about the above three fiber-shaped sensors are presented in the later section.Despite the great progress made in fiber and textile electronics, we have to realize that most of the research results are far from practical applications due to several existing obstacles. The performances of fiber-shaped electronic devices are not good enough to attract investors. For instance, although fiber-shaped solar cells have achieved a record power conversion efficiency (PCE) of 10%, [36] this value falls far below the certified efficiency of 24.2% for planar solar cells. [37] Besides, fiber-shaped electronic devices often decay in performance further as their lengths increase. Apart from low performances, scalable fabrication is another hard nut to crack if fiber-shaped electronic devices are to be commercialized. For one thing, researchers usually can only realize fiber-shaped electronic devices with the lengths from several to hundreds of millimeters at present owing to the absence of appropr...
