Microfluidics-derived microfibers in flexible bioelectronics

AbstractFlexible electronics have attracted extensive attention across a wide range of fields due to their potential for preventive medicine and early disease detection. Microfiber-based textiles, encountered in everyday life, have emerged as promising platforms with integrated sensing capabilities. Microfluidic technology has been recognized as a promising avenue for the development of flexible conductive microfibers and has made significant achievements. In this review, we provide a comprehensive overview of the state-of-the-art advancements in microfiber-based flexible electronics fabricated using microfluidic platforms. Firstly, the fundamental strategies of the microfluidic fabrication of conductive microfibers with different structures and morphologies are introduced. Subsequently, attention is then directed towards the diverse applications of these microfibers in bioelectronics. Finally, we offer a forward-looking perspective on the future challenges about microfluidic-derived microfibers in flexible bioelectronics.
