“…For example, carbodiimide cross-linker chemistry was widely used for fiber electrodes to be functionalized with enzymes, while an in situ electrochemical reductive reaction can easily deposit the electrodes with a variety of functional nanoparticles . The other fiber electrode modification technologies, including physical adsorption, thermal evaporation, and CVD thin-film deposition, are also widely used for fabricating fiber devices . Note that 3D printing and thermal drawing have been further developed with one-step fabrication of functional fiber electrodes, eliminating the need for post-treatments of fiber electrodes. , …”

The development of fiber materials has accompanied the evolution of human civilization for centuries. Recent advances in materials science and chemistry offered fibers new applications with various functions, including energy harvesting, energy storing, displaying, health monitoring and treating, and computing. The unique one-dimensional shape of fiber devices endows them advantages to work as human-interfaced electronics due to the small size, lightweight, flexibility, and feasibility for integration into large-scale textile systems. In this review, we first present a discussion of the basics of fiber materials and the design principles of fiber devices, followed by a comprehensive analysis on recently developed fiber devices. Finally, we provide the current challenges facing this field and give an outlook on future research directions. With novel fiber devices and new applications continuing to be discovered after two decades of research, we envision that new fiber devices could have an important impact on our life in the near future.

Fibers and textiles are attractive substrates for constructing wearables, the devices rely on conductive fibers with good stretchability to realize electrical conductivity and mechanical adaptivity. The exploitation of stretchable composite conductive fibers (SCCFs) requires diverse strategies in material options and process methods, tackling the challenge in balancing electrical and mechanical properties for ultrafine fiber, which highly determine the properties and applications. In this article, first the working mechanism and advantages of the SCCFs in wearables is introduced. Second, different conductive fillers as well as their respective incorporation strategies and performance superiorities in fabricating SCCFs are systematically summarized. Third, the integration routes of the conductive fillers in SCCFs are indicated and compared, presenting different fabrication strategies and mechanisms for improving the performance of SCCFs. Thereafter, the typical applications of SCCFs in energy management, sensing, actuators, heaters, and displays are highlighted. Accordingly, the main challenges of SCCFs for wearable applications are indicated, and the possible solutions for challenges tackling are proposed. This review prepared aims to highlight the importance of SCCFs in wearables, and provides insights in terms of mechanism, materials, fabrication, and performance improvement, paving a referable way to promote the innovative exploitation and development of SCCFs, extending the application scenarios.
