Abstract

Flexible light-emitting fibers and fabrics serve to bridge human-machine interactions.The desire for practical applications and the commercialization of flexible light-emitting fibers has accelerated struc-tural progress and improvements.This review focuses on the structural design of light-emitting fibers and fabrics,starting with a summary of design principles,emission mechanisms,and structural evolution of coaxial structured light-emitting fibers.Subsequently,we explore recent advances in the helical struc-ture design strategies that boost the mechanical sensitivity of light-emitting fibers.Following that,we analyze continuous preparation processes and the development of large-area intelligent light-emitting fabrics based on interwoven structures.Examples based on stiff and rigid inorganic-based light-emitting diodes integrated into flexible systems are also presented.Finally,we discuss the current chal-lenges and future opportunities for light-emitting applications in the field of wearable and smart devices.
