摘　　要：为了解决离子凝胶型离子皮肤应用场景受限的问题,本文提出了以柔软舒适的纺织结构为基体的离子凝胶型离子皮肤的研究策略。采用模板法在水性聚氨酯共混离子液体的离子凝胶表面制造了密集且不规则的突出结构,与针织电极组成三明治结构的离子皮肤,并对其物理性能和传感性能进行研究。测试结果表明,该纺织基离子皮肤在低压范围(0~20 kPa)有更高的灵敏度(约8.39 kPa^(-1)),滞后性低(DH=2.2%),在超过5000次循环压缩测试后仍能保持电容信号变化的稳定,同时表现出优异的动态监测能力。纺织基离子皮肤实现了对人体动态信号稳定可靠的监测,在运动训练、人机交互等领域具有广阔的应用前景。As interest in human-machine interaction and health monitoring continues to rise,the field of flexible electronics has accelerated its development,with flexible electronic skin becoming a focal point of research.Traditional rigid conductive materials used to construct electronic skin often fail to provide stable sensing under high deformation,presenting issues such as low biocompatibility and opacity.These limitations necessitate the urgent development of wearable flexible electronic skin that can meet user needs effectively.This study aims to address the problem of limited application scenarios for ionogel-based ionic skin by proposing a research strategy centered on the use of a soft and comfortable textile structure as the substrate for the ionogel.Inspired by the ion conduction function of human skin,we explored the potential of stretchable ionic conductors,which transmit electrical signals similarly to human skin.Recent years have witnessed the widespread application of ionic skin in flexible wearable technology,including robotics,medical monitoring,and human-machine interaction.The ionic skin can be categorized into several types,including organic gels,conductive hydrogels,and ionogels.However,organic gels often exhibit low conductivity and poor biocompatibility,making them unsuitable for wearable applications related to human interaction.Conductive hydrogels,on the other hand,are susceptible to environmental humidity and temperature changes,which adversely affect their mechanical properties and electrical signal stability.This variability severely impacts sensing performance and restricts the application of sensors in practical scenarios.In this context,ionic liquids represent a green electrolyte with outstanding thermal stability,chemical stability,ionic stability,conductivity,and interfacial capacitance.Ionogels composed of ionic liquids and polymers have been developed to overcome the water loss problem associated with ionic hydrogels.These gels serve as effective materials for capacitive pressure sensi
