Abstract

In recent years, the collection and monitoring of human physiological signals have garnered increasing attention due to their wide-ranging applications in healthcare, human–machine interaction, sports, and other fields. However, the continuous fabrication of flexible gel fiber electrodes with high mechanical performance, high conductivity, and durability for extreme environments using a simple, efficient, and universal strategy remains challenging for physiological signal acquisition. Here, we have employed a strategy of solvent replacement and multi-level hydrogen bond enhancement to construct eutectogel fibers with continuous solid–liquid structure, achieving continuous production of fibers with high strength, high conductivity, and low-temperature resistance. In the fiber, PVA serves as the solid-state elastic phase, DES as the liquid ionic conductive phase, and CNF as the reinforcement phase. The resulting eutectogel fibers exhibit excellent tensile strength (37.3 MPa), good elongation (> 700%), high electrical conductivity (0.543 S/m), and resistance to extreme dry and −60 °C low-temperature environments. Furthermore, these eutectogel fibers demonstrate high sensitivity for monitoring joint movements and effectively detecting in vitro and in vivo signals, show casing their potential for wearable strain sensors and monitoring physiological signals.

通过连续湿法纺丝生产的机械和传导性强的共晶凝胶纤维可进行表皮和植入式电生理监测
近年来,人体生理信号的采集和监测因其在医疗保健、人机交互、体育运动等领域的广泛应用而日益受到关注。然而,采用简单、高效、通用的策略连续制造出具有高机械性能、高导电性和极端环境下耐用性的柔性凝胶纤维电极,对于生理信号的采集仍具有挑战性。在此,我们采用溶剂置换和多级氢键增强的策略,构建了具有连续固液结构的共晶凝胶纤维,实现了高强度、高导电性和耐低温纤维的连续生产。在纤维中,PVA 作为固态弹性相,DES 作为液态离子导电相,CNF 作为增强相。由此制成的共晶凝胶纤维具有出色的拉伸强度(37.3 兆帕)、良好的伸长率(700%)、高导电率(0.543 S/m)以及耐极端干燥和 -60 °C 低温环境的特性。此外,这些共晶凝胶纤维在监测关节运动和有效检测体外及体内信号方面表现出很高的灵敏度,显示了它们在可穿戴应变传感器和监测生理信号方面的潜力。
