Fiber-based structures are highly desirable for wearable electronics that are expected to be light-weight, long-lasting, flexible, and conformable. Many fibrous structures have been manufactured by well-established lost-effective textile processing technologies, normally at ambient conditions. The advancement of nanotechnology has made it feasible to build electronic devices directly on the surface or inside of single fibers, which have typical thickness of several to tens microns. However, imparting electronic functions to porous, highly deformable and three-dimensional fiber assemblies and maintaining them during wear represent great challenges from both views of fundamental understanding and practical implementation. This article attempts to critically review the current state-of-arts with respect to materials, fabrication techniques, and structural design of devices as well as applications of the fiber-based wearable electronic products. In addition, this review elaborates the performance requirements of the fiber-based wearable electronic products, especially regarding the correlation among materials, fiber/textile structures and electronic as well as mechanical functionalities of fiber-based electronic devices. Finally, discussions will be presented regarding to limitations of current materials, fabrication techniques, devices concerning manufacturability and performance as well as scientific understanding that must be improved prior to their wide adoption.

“…In this regard, recent advances toward developing various high‐performance 1D stretchable conductive yarns are considerably remarkable based on the convergence of textile technologies, electronics, and nanotechnologies . Although the achievements of 1D stretchable electronic devices are still not significant compared to those of the existing 2D stretchable electronic devices, the related fields have actively expanded because of the potential applications of this 1D stretchable electronics technology such as military garment devices, biomedical and antimicrobial textiles, smart sportswear, and personal electronics …”

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...

particular 3D structure, such as sponges, the electroconductivity is poorly containable because the 3D structure, as a spatial mask, decreases the uniformity and continuity of the deposited metal films initiated by gravity. [18] Recently, Liu et al. reported the polymer-assisted metal deposition by surface-initiated atomic transfer radical polymerization. [19] The designed polymer interface introduces covalent bonds between the surface of fibers and grafted polymer brushes and viscoelastic and high-swelling intrinsic properties of polymers provide the nanometer-scale mechanical interlocking of deposited nanoparticles within brushes. Although the resultant conductive yarns are highly durable and washable, the polymerization requires an inert N 2 protection and complex steps. Moreover, the target substrates have to contain abundant hydroxyl groups. On the other hand, with the booming development of novel materials, which can be employed in wearable electronics as their variety of performances, how to develop a new surface modification method which can be used in virtually any substrate and create conductive composites is important.According to Lee's report, [20] dopamine which mimics the adhesive chemistry of mussel plaque detachment allows the spontaneous deposition of nanoscale-thin, surface-adherent films of poly(dopamine) (PDA) on virtually all material surfaces such as polymers, ceramics, semiconductors, and novel metals by simple dip-coating in an alkaline solution. More importantly, secondary reactions can be used to produce a variety of ad-layers on the top of PDA, including metal films by electroless metallization. [21] In some reports, silver (Ag) was coated on different fibers, such as polyester polyethylene terephthalate (PET), meta-aramid, glass, cotton, and polyurethane, via PDA-assisted electroless deposition (ELD). [22][23][24][25][26] However, in accordance with Zheng's review work, [27] silver, as a conductive coating material, is much more expensive than copper and nickel. More importantly, according to the European Commission and its nonfood Scientific Committee on Emerging and Newly Identified Health Risks, there are still some arguments related to the toxicity of silver nanoparticles and additional adverse effects caused by the use of silver nanoparticles should be further evaluated.To address the challenges, we report here a simple, versatile, and scalable approach for preparing highly durable, washable, and electrically conductive fibers and yarns by electroless nickel (Ni) plating on fiber surfaces modified with PDA as adhesive layers. Copper (Cu) can be an alternative coating choice due to the high conductivity and low price. However, the Here a bioinspired facile and versatile method is reported for fabricating highly durable, washable, and electrically conductive fibers and yarns. Self-polymerized dopamine plays as adherent layers for substrates and then captures Pd 2+ catalyst for subsequent metal deposition on substrates. The Pd 2+ ions are chelated and partially reduced to nanoparticl...
