Fiber-optic sensors are attracting attention because of their high sensitivity, fast response, large capacity-transmission, and anti-electromagnetic interference advantages. Nevertheless, rigid optical fibers are inevitably damaged or even fractured in applications involving large tensile or bending strains (e.g., human body monitoring, soft robotics, and biomedical devices) and the position of the fracture is difficult to locate and repair. Therefore, optically self-healing fiber-optic sensors are highly desirable. Here, we report a design strategy for increasing the polymer segmental mobility and reversible non-covalent bond density of poly(polymerizable deep eutectic solvent) (PDES) to continuously fabricate a core–cladding poly(PDES) optical fiber (CPOF) with significant optical, electrical, and mechanical self-healing abilities. It also possesses low optical propagation attenuation (0.31 dB cm–1), wide temperature tolerance (−77–168 °C), and excellent biocompatibility. Moreover, CPOFs have been validated for gesture recognition, subcutaneous self-healing, and pressure–temperature detection, owing to their ability to transmit dual optical-electrical signals in real time, and are promising for various applications in industrial and technological fields.

自修复多模式柔性光电光纤传感器
光纤传感器以其灵敏度高、响应速度快、传输容量大、抗电磁干扰等优点而备受关注。然而，刚性光纤在涉及大拉伸或弯曲应变的应用（如人体监测、软体机器人和生物医学设备）中不可避免地会损坏甚至断裂，并且断裂的位置难以定位和修复。因此，非常需要光学自愈光纤传感器。在这里，我们报告了一种增加聚（可聚合低共熔溶剂）（PDES）的聚合物链段迁移率和可逆非共价键密度的设计策略，以连续制造具有显着光学性能的芯包层聚（PDES）光纤（CPOF） 、电气和机械自愈能力。–1 )、宽温度耐受性 (−77–168 °C) 和出色的生物相容性。此外，由于 CPOF 能够实时传输双光电信号，因此在手势识别、皮下自愈和压力-温度检测等方面得到了验证，在工业和技术领域的各种应用前景广阔。
