“…However, these materials have high elastic modulus and limited flexibility unless the films are extremely thin. This leads to a significant trade-off between their flexibility and areal energy storage performance, in which thinner electrodes present higher flexibility but lower areal capacitance [ 40 ]. Other rigid and brittle electrode materials can also be assembled into flexible electrodes with the assistance of flexible substrates, such as plastic thin films and wearable textiles [ 21 , 29 , 37 , 38 ].…”

“…Some extreme deformations, such as folding, are actually equivalent to bending at an extreme radius. Many reports among others have successfully demonstrated high flexibility and durability through bending at extremely small radii [ 59 ] or folding for many cycles [ 40 , 106 , 107 ], which are recommended tests for future fiber supercapacitors.…”

“…The equation tells us that a desired bending stiffness or flexibility of a piece of textile or fabric can be achieved through the design of the material’s elastic modulus and the control of its thickness. In fact, most of the materials for flexible supercapacitors can be considered composites that combine electrode materials and polymer-based electrolytes [ 40 ]. Although some frequently reported electrode materials such as carbon nanotubes and graphene are considered intrinsically flexible materials, they actually have extremely high elastic modulus ranging from 100 to 1000 GPa [ 39 , 116 ].…”

Future wearable electronics and smart textiles face a major challenge in the development of energy storage devices that are high-performing while still being flexible, lightweight, and safe. Fiber supercapacitors are one of the most promising energy storage technologies for such applications due to their excellent electrochemical characteristics and mechanical flexibility. Over the past decade, researchers have put in tremendous effort and made significant progress on fiber supercapacitors. It is now the time to assess the outcomes to ensure that this kind of energy storage device will be practical for future wearable electronics and smart textiles. While the materials, fabrication methods, and energy storage performance of fiber supercapacitors have been summarized and evaluated in many previous publications, this review paper focuses on two practical questions: Are the reported devices providing sufficient energy and power densities to wearable electronics? Are the reported devices flexible and durable enough to be integrated into smart textiles? To answer the first question, we not only review the electrochemical performance of the reported fiber supercapacitors but also compare them to the power needs of a variety of commercial electronics. To answer the second question, we review the general approaches to assess the flexibility of wearable textiles and suggest standard methods to evaluate the mechanical flexibility and stability of fiber supercapacitors for future studies. Lastly, this article summarizes the challenges for the practical application of fiber supercapacitors and proposes possible solutions.

“…Textiles have been widely used as a perfect media in various applications such as thermal management, wearable electronics and energy storage, because of their unique physical properties (e.g., softness, stretchability, scalability) [17][18][19]. Fiber is the most basic component for textile materials and has many excellent features, including high flexibility, excellent mechanical properties and large surface-area-to-volume ratios [20].…”

Three-dimensional printing (3DP) allows for the creation of highly complex products and offers customization for individual users. It has generated significant interest and shows great promise for textile and fashion design. Here, we provide a timely and comprehensive review of 3DP technology for the textile and fashion industries according to recent advances in research. We describe the four 3DP methods for preparing textiles; then, we summarize three routes to use 3DP technology in textile manufacturing, including printing fibers, printing flexible structures and printing on textiles. In addition, the applications of 3DP technology in fashion design, functional garments and electronic textiles are introduced. Finally, the challenges and prospects of 3DP technology are discussed.
