“…Recently, a deep investigation of which materials constitute suitable elastic claddings through understanding their rheological properties has been performed by Prof. Fabien Sorin's group at the École Polytechnique Fédérale de Lausanne in Switzerland. [87][88][89][90][91][92][93] They first investigated the complex shear viscosity as well as the storage and loss moduli of some thermoplastics commonly used as claddings for thermal drawing. They discovered that a stable flow in the viscous regime can be identified by a temperature window in which the loss modulus changes slowly with temperature, crossing over the storage modulus that rapidly decreases, as shown by the rheological characterization in Figure 6b (middle).…”

Fibers are the building blocks of a broad spectrum of products from textiles to composites, and waveguides to wound dressings. While ubiquitous, the capabilities of fibers have not rapidly increased compared to semiconductor chip technology, for example. Recognizing that fibers lack the composition, geometry, and feature sizes for more functions, we set out years ago to explore the boundaries of fiber functionality. Our approach focused on a particular form of fiber production, thermal-drawing from a preform. This process has been used for producing single material fibers, but by combining metals, insulators, and semiconductors all within a single strand of fiber, an entire world of functionality in fibers has emerged. Fibers with optical, electrical, acoustic, or optoelectronic functionalities can be produced at scale from relatively easy-to-assemble macroscopic preforms. Two significant opportunities now present themselves. First, can we expect that fiber functions escalate in a predictable manner, creating the context for a "Moore's Law" analogue in fibers? Second, as fabrics occupy an enormous surface around our bodies, could fabrics offer valuable service to augment the human body? Towards answering these questions, we detail the materials, performance, and limitations of thermally-drawn fibers in different electronic applications and envision their potential in new fields.

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...

Fabrics are an indispensable part of our everyday life. They provide us with protection, offer privacy, and form an intimate expression of ourselves through their aesthetics. Imparting functionality at the fiber level represents an intriguing path toward innovative fabrics with a hitherto unparalleled functionality and value. The fiber technology based on thermal drawing of a perform, which is identical in its materials and geometry to the final fiber, has emerged as a powerful platform for the production of exquisite fibers with prerequisite composition, geometric complexity, and control over feature size. A ‘Moore's law’ for fibers is emerging, delivering higher forms of function that are important for a broad spectrum of practical applications in healthcare, sports, robotics, space exploration, etc. In this Review, we survey progress in thermally-drawn fibers and devices and discuss their relevance to ‘smart’ fabrics. A new generation of fabrics that can see, hear and speak, sense, communicate, harvest and store energy, as well as store and process data is anticipated. We conclude with a critical analysis of existing challenges and opportunities currently faced by thermally-drawn fibers and fabrics that are expected to become sophisticated platforms delivering value-added services for our society.
