摘　　要：近年来,可穿戴智能系统的进步对柔性压力传感器提出迫切的需求。其中,电阻式柔性触觉传感器因其原理简单、易于加工、集成效率高等特点得到了迅速发展。但是,如何实现传感器在宽压力监测范围内,具有高灵敏度仍是研究者们要面临的挑战。为了解决上述问题,除了选择先进的功能材料和合适的衬底材料,优化传感器结构也是一个重要的研究方向。本文立足于传感器件的结构设计,分别介绍了一维的纤维纱线传感器件,基于表面微结构、纳米结构构筑的二维平面传感器件及具有空间结构和高空隙的多维立体结构传感器件,通过以上结构设计实现了传感器件性能的提升,最后分析了其在医养健康领域的实际应用进展。The working principle of resistive flexible tactile sensors is mainly based on the piezoresistive effect.When the sensor is subjected to external pressure,the external pressure is converted into a resistance signal,thereby generating an electrical output signal.In recent years,the advancement of wearable smart systems has created an urgent demand for flexible pressure sensors.Among them,resistive flexible tactile sensors have experienced rapid development due to their simple principle,ease of processing,and high integration efficiency.Although biomimetic electronic skins based on resistive flexible tactile sensors have been widely applied in various fields such as human-computer interaction,wearable medical devices,and smart robots,to obtain sensors with a wide pressure monitoring range and high sensitivity remains a challenge for researchers.To address the aforementioned issues,in addition to selecting advanced functional materials and suitable substrate materials,optimizing sensor structure is also an important research direction.Rational structural design can not only significantly enhance the sensitivity and other performance parameters of the sensor but also flexibly adjust its sensitivity and response characteristics to meet specific application requirements.Currently,the structural design of resistive flexible tactile sensors can be divided into three dimensions:one-dimensional fiber yarn-based sensor elements,two-dimensional planar structure sensor elements,and multi-dimensional three-dimensional structure sensor elements.Innovatively designing the sensor layers in different dimensions to change the contact resistance between conductive materials and the conduction paths in conductive elastic composites is currently an important research direction to improve the performance of resistive tactile sensors.The existing structural design of one-dimensional fiber yarn-based sensor elements is mainly based on the core-shell structure achieved through coaxial spinning.Although it exhibits high linearity,the sensi
