Advanced Functional Fiber and Smart Textile

The research and applications of fiber materials are directly related to the daily life of social populace and the development of relevant revolutionary manufacturing industry. However, the conventional fibers and fiber products can no longer meet the requirements of automation and intellectualization in modern society, as well as people's consumption needs in pursuit of smart, avant-grade, fashion and distinctiveness. The advanced fiber-shaped electronics with most desired designability and integration features have been explored and developed intensively during the last few years. The advanced fiber-based products such as wearable electronics and smart clothing can be employed as the second skin to enhance information exchange between humans and the external environment. In this review, the significant progress on flexible fiber-shaped multifunctional devices, including fiber-based energy harvesting devices, energy storage devices, chromatic devices, and actuators are discussed. Particularly, the fabrication procedures and application characteristics of multifunctional fiber devices such as fiber-shaped solar cells, lithium-ion batteries, actuators and electrochromic fibers are introduced in detail. Finally, we provide our perspectives on the challenges and future development of functional fiber-shaped devices.
