“…CNTT can be used to bridge soft components and sensors to traditional electronic components, making them a key component toward the development of fully textile-based circuits. CNTT-derived technologies such as antennas, light-emitting diodes, or semiconducting fibers can be similarly sewn into textiles. Moreover, minor modifications to CNTT geometry and microelectronics could allow other health-monitoring applications including blood pressure, force exertion, and respiratory rate sensing capabilities.…”

Smart wearable electronic accessories (e.g., watches) have found wide adoption; conversely, progress in electronic textiles has been slow due to the difficulty of embedding rigid electronic materials into flexible fabrics. Electronic clothing requires fibers that are conductive, robust, biocompatible, and can be produced on a large scale. Here, we create sewable electrodes and signal transmission wires from neat carbon nanotube threads (CNTT). These threads are soft like standard sewing thread, but they have metal-level conductivity and low interfacial impedance with skin. Electrocardiograms (EKGs) obtained by CNTT electrodes were comparable (P > 0.05) to signals obtained with commercial electrodes. CNTT can also be used as transmission wires to carry signals to other parts of a garment. Finally, the textiles can be machine-washed and stretched repeatedly without signal degradation. These results demonstrate promise for textile sensors and electronic fabric with the feel of standard clothing that can be incorporated with traditional clothing manufacturing techniques.

“…In addition to using commercial nonconductive polymer fibers, conductive fibers can be directly used for coating functional materials. For example, perovskite-CNT light-emitting fibers were obtained by integrating CNT fibers with organic-inorganic emissive composite layers through an all-solution-processed method (Figure 5D) (Jamali et al, 2020). However, the distribution of the active materials on/along the fibers and the solvent compatibility in the dipping process remain a challenge.…”

Wearable electronics are receiving increasing attention with the advances of human society and technologies. Among various types of wearable electronics, electronic fibers/textiles, which integrate the comfort and appearance of conventional fibers/textiles with the functions of electronic devices, are expected to play important roles in remote health monitoring, disease diagnosis/treatment, and human-machine interface. This article aims to review the recent advances in electronic fibers/textiles, thus providing a comprehensive guiding reference for future work. First, we review the selection of functional materials and fabrication strategies of fiber-shaped electronic devices with emphasis on the newly developed functional materials and technologies. Their applications in sensing, light emitting, energy harvest, and energy storage are discussed. Then, the fabrication strategies and applications of electronic textiles are summarized. Furthermore, the integration of multifunctional electronic textiles and their applications are summarized. Finally, we discuss the existing challenges and propose the future development of electronic fibers/textiles. INTRODUCTIONRecently, development of flexible and wearable electronics has been gradually prominent in our daily life (Park et al., 2018;Trung and Lee, 2016). Ideal wearable electronics possess characteristics of flexibility, light weight, easy to bind with human skin, and tolerating mechanical deformation, to satisfy the requirements of comfort and avoid interfering with normal activities of humans (Zeng et al., 2014). However, traditional electronics with high performance are mostly made of bulky and rigid inorganic materials, such as silicon or gallium arsenide, which are used for fabrication of complex planar circuits (Fan et al., 2008; Kim et al., 2009). The mechanical mismatch between rigid electronics and human skin has immensely prevented electronic devices from conformably attaching on the human body. Therefore, electronic devices are gradually developing toward flexibility and miniaturization to fulfill the requirements of wearing, and have developed from three dimensional (3D) rigid devices to low-dimensional and lightweight flexible devices. Electronics in forms of fibers and textiles, with advantages of good flexibility, light weight, breathability, and easiness of integration with traditional clothes, are one of the ideal form of wearables (Chatterjee et al., 2019).Although fibers have been used in human lives for thousands of years, the history of developing functional and intelligent fibers is not long. Before the emergence of flexible and wearable electronics, optical fibers and metal fibers were the representative functional fibers (Kao and Hockham, 1966;Wardclose and Partidge, 1990). Recently, with the progress of material science and nanotechnology, wearable electronic fibers/ textiles, including 1D fiber-shaped electronic devices (electronic fibers) and 2D/3D electronic textiles, which combine the flexibility and excellent mechanical properties of fib...

“…Additionally, the inherent properties of fibres, such as high surface area and the ability to be intertwined and twisted in various directions, offers unprecedented degrees of freedom, enabling creative device design configurations which are not possible in planar electronics. A wide range of fibre-based electronic devices such as transistors, [1][2][3] photodiodes, 4,5 photodetectors, 6,7 solar cells, [8][9][10][11] batteries, [12][13][14][15] supercapacitors, [16][17][18][19][20][21][22][23][24][25] triboelectric nanogenerators, [26][27][28][29][30][31] and sensors 23,[32][33][34][35][36][37][38][39] have been produced. These fibre-based devices (FBDs) have also been integrated into multifunctional electronic textile (e-textile) systems, capable of performing more than one task at the same time such as integrated energy harvesting and storage systems and self-powered touch, strain, or pressure sensing systems.…”
