摘　　要：触觉传感器是智能可穿戴设备和人机交互领域的重要研究方向,引起了人们广泛的关注。传统刚性材料的触觉传感器普遍存在坚硬且不适合穿戴交互等瓶颈问题,限制了其在可穿戴领域的应用。纺织基柔性触觉传感器由于其高灵敏性、柔软性和可穿戴性成为触觉传感材料的首选。本文综述了几类纺织基柔性触觉传感器的原理和应用,包括电阻式、电容式、压电式和摩擦电式。结果表明:纺织基柔性触觉传感器由于其特殊的纺织结构,有优异的线性度、灵敏度、耐久性和稳定性。高灵敏性、耐久性和可穿戴性是纺织基柔性触觉传感器的优势和重要发展方向。Tactile sensors are an important research direction in the field of smart wearable devices and human-computer interaction, which has attracted extensive attention. Tactile sensors of traditional rigid materials generally have bottlenecks such as being hard and not suitable for wearable interaction, which limits their application in the wearable field. Textile-based flexible tactile sensors have become the first choice for tactile sensing materials due to their high sensitivity, softness, and wearability.The textile-based flexible tactile sensor is a new development direction of flexible sensors for the following reasons. First, its special textile structure can be seamlessly connected with clothing to achieve the integration of design, wear and application. Second, sensors with different dimensions can be developed at different stages of textiles, and there are one-dimensional fiber and yarn sensors, two-dimensional fabric sensors and three-dimensional clothing textiles. The sensing application range in different dimensions is different. Compared with the low response and high sensitivity based on the fiber/yarn sensor, the fabric/textile sensor has a larger sensing area and a more ideal array design. More importantly, wearable devices that combine sensing with textiles have excellent sensing performance and comfort, and can be widely used in medical care, sports detection, leisure and entertainment and other fields.This paper reviews the principles and applications of several types of textile-based flexible tactile sensors, including resistive, capacitive, piezoelectric, and triboelectric ones. The results show that the textile-based flexible tactile sensor has excellent linearity, sensitivity, durability and stability due to its special textile structure. The textile-based flexible resistive tactile sensor has a simple structure and can achieve high performance and low cost. However, the energy consumption is high and the recovery rate is low. Future directions are to design materials in which resistance change
