“…2i), suggesting a decrease in crystal plane distance from 4.29 to 4.20 Å and an increase in crystallinity of PEDOT:PSS. 48,49 In addition, the full width at half maximum (FWHM) of the peak decreased from 0.581 to 0.541, double confirming the increase in crystallinity. As a result, the conductivity of the semiconductor film could be increased after the inclusion of Nafion, which will be discussed later.…”

“…A superior strategy is employing the semiconducting polymer itself as an electrode to prevent interfacial issues and provide more stable fiber device performance. Jo et al prepared a fibrous OECT device by identifying the region where the PEDOT:PSS conductive fibers are infiltrated with the electrolyte as the trench and the remaining regions as the source, drain, and gate electrodes . The manufactured conductive fibers exhibited electrical characteristics of 19 mS at V G = 0.1 V, which was remarkably greater than the previously reported fiber-shaped OECT.…”

Fibers, originating from nature and mastered by human, have woven their way throughout the entire history of human civilization. Recent developments in semiconducting polymer materials have further endowed fibers and textiles with various electronic functions, which are attractive in applications such as information interfacing, personalized medicine, and clean energy. Owing to their ability to be easily integrated into daily life, soft fiber electronics based on semiconducting polymers have gained popularity recently for wearable and implantable applications. Herein, we present a review of the previous and current progress in semiconducting polymer-based fiber electronics, particularly focusing on smart-wearable and implantable areas. First, we provide a brief overview of semiconducting polymers from the viewpoint of materials based on the basic concepts and functionality requirements of different devices. Then we analyze the existing applications and associated devices such as information interfaces, healthcare and medicine, and energy conversion and storage. The working principle and performance of semiconducting polymer-based fiber devices are summarized. Furthermore, we focus on the fabrication techniques of fiber devices. Based on the continuous fabrication of one-dimensional fiber and yarn, we introduce two-and three-dimensional fabric fabricating methods. Finally, we review challenges and relevant perspectives and potential solutions to address the related problems.

lightweight, portable, foldable, stretchable, and biocompatible are triggering the intense interests of researchers from multidisciplinary fields like biology, material science, and chemistry. [9][10][11] Nowadays, great attempts have been devoted to developing advanced flexible electronics by integrating various inorganic or organic traditional conductive functional materials with flexible electrochemically non-active elastic substrates. [12][13][14][15][16][17] Generally, traditional conductive functional materials encounter the shortcomings such as high price, inherent rigidity, weak biocompatibility, poor mechanical, and inferior interface bonding properties, which are employed to evaluate the performance of the flexible electronics materials. Therefore, pursuing these materials with practical applications is an emergent issue in the research field.Nevertheless, in numerous conductive functional materials, hydrogels with 3D network structures have been largely selected as the excellent candidates due to their high water content, excellent biocompatibility and biodegradability properties, high elasticity, and outstanding stimulus responsiveness. [18][19][20][21][22][23] Conductive hydrogels are generally constructed via integrating various conductive substances into the hydrogel matrix, which are comprised of carbon materials (carbon nanotubes (CNTs), graphite), metal oxides, metal sulfides, metal nanoparticles and conductive polymers (polyaniline (PANI), polypyrrole (PPy), poly (3,4-ethylenedioxythiophene) (PEDOT:PSS)). [24][25][26][27][28][29][30] For example, Han et al. fabricated a CNTs-based conductive hydrogel for strain sensors by in situ polymerization of acrylic acid and acrylamide in water/glycerol solutions in the presence of polydopamine-decorated CNTs. [28] Devaki et al. reported a 3D Ag nanoparticles-polyacrylic acid conductive hydrogel via combining in situ polymerization of acrylic acid and reduction of Ag + . [29] Duan et al. constructed a robust and force-sensitive conductive hydrogel employing synthesizing polyacrylamide and PANI in closely packed swollen chitosan microspheres. [30] According to the different configurations of hydrogels, conductive hydrogels are allowed to be processed into 3D bulk gels, 2D gel films, 1D gel fibers, and 0D microgels. [31][32][33][34][35][36] The mechanical flexibility of 1D fibrous configuration is superior to that of 3D bulk or 2D film configuration due to its well-oriented polymer chains, light weight, and low dimensions for flexible electronics. Moreover, ultra-flexible fibrous materials can be easily woven into diverse soft and breathable fabrics, which
