Due to their excellent flexibility, lightweight, and integrating potential, wearable electronic devices have recently gained increasing attention. To satisfy and match the demand for wearable electronics, wearable power systems are required, such as fiber-shaped energy conversion and/or storage devices. Up to now, fiber-shaped solar cells, supercapacitors, and batteries have been developed on the basis of metal wire electrodes, carbon nanotube fibers, and graphene fibers. Compared to other fiber electrodes, graphene fibers assembled from functionalized graphene have not only shown high electrical conductivity and mechanical strength, but also excellent flexibility and ease of production at large scale. In this chapter, the fabrication and properties of graphene fibers are summarized in detail, followed by reviewing the recent advances on graphene fiber-based wearable energy conversion and storage devices including solar cells, supercapacitors, and batteries. In addition, fiber-shaped wearable integrated energy conversion and storage devices are also demonstrated. Finally, future challenges and perspectives on this hot topic are discussed.
