Abstract The unique 1D structure of fibers offers intriguing attributes, including a high length‐to‐diameter ratio, miniatured size, light‐weight, and flexibility, making them suitable for various biomedical applications, such as health monitoring, disease treatment, minimally invasive surgeries. However, traditional fiber devices, typically composed rigid, dry, non‐living materials, are intrinsically different from the soft, wet, living essence biological tissues, thereby posing grand challenges long‐term, reliable, seamless interfacing with systems. Hydrogel have recently emerged promising candidate, in light their similarity to tissues mechanical, chemical aspects, well distinct geometry. In this review, comprehensive overview recent progress hydrogel fibers‐based biointerfacing technology is provided. It thoroughly summarizes manufacturing strategy functional design, especially optical electron conductive performance, responsiveness triggers thermal, magnetic field ultrasonic wave, etc. Such attributes enable which also examined detail. Future potential directions, biosafety, long‐term reliability, sterilization, multi‐modalities integration intelligent therapeutic systems, raised. This review will serve valuable resource further advancement implementation next‐generation technology.

Bioluminescent organisms, such as fireflies, jellyfish, and glow worms, possess a superb capacity for environment-interactive luminescence, enabling them to adapt their surroundings. However, developing artificial luminescent materials that mimic the wet, soft, flexible, multistimuli-responsive nature of bioluminescent organisms remains challenge. Here, we present rational design strategy fluorescent hydrogels in diverse complex shapes, mimicking behavior fireflies. The fluorescence is activated enhanced by natural sustainable stimuli─water temperature─and can be reversibly deactivated on-demand, similar role oxygen temperature firefly bioluminescence. Specifically, designed molecular additives integrated within hydrogel matrix increase intensity enhance reversible repetitive responsiveness surrounding solvents without diminishing intensity. Moreover, responding changes enables control fluorescence. Furthermore, precursor, good printability, allows 3D printing diverse-shaped structures, including organism models fluorescence-patterned displays. This capability extends implementing on-demand dynamic information encryption-decryption display with controllable on-off rates. proposed free-form fabrication could provide viable path toward advanced development.
