Optoelectronic functional fiber: materials, fabrication, and application for smart textiles

In recent years, great progress has been made in integration of optoelectronic materials and fabrication technologies to improve the performance and simplify the device architecture. For next-generation optoelectronic applications, fibers are promising candidates for constructing diverse flexible and miniature electronics/optoelectronics. Recent advances of flexible fibers in integrating the functional materials with diverse optoelectronic properties open up the potential for advanced optical probes, functional surfaces, and smart textiles. In this paper, we highlight the recent advances of optoelectronic functional fibers in material selection, especially of organic materials, fabrication approaches, as well as their applications in energy conversion, photoelectric sensing, and logical response. We conclude by pointing out the challenges and future research direction in this area.
