摘　　要：机织结构的导电液体传感织物能检测微量导电液体的泄漏,但不能反馈泄漏位置。因此,基于交叉扫描原理设计了导电液体微量泄漏定位检测织物。该织物布边设有2n根导电经纱,将他们平均分成两组,每组中的经纱通过重经组织与均匀布设的导电纬纱交叉地电气相连,形成n^(2)个检测组合,对应织物经向上n^(2)个定位分区。采用织样机试织了含有6根导电经纱、9个定位分区的织物,并对织物进行了切片观察、电气测试、功能验证试验和适配检测系统的开发。结果发现:重经组织结构可以实现织物中导电经纬纱在交汇时的可靠绝缘;重经组织结构重复性良好,可以适应规模化生产;交叉扫描方式能正确反馈泄漏所在分区;由自动选通电路和导通鉴别电路构成的检测系统与织物匹配良好。Conductive liquids are generally easy to detect due to their conductivity.However,sensors arranged at a single point can only be effective when a large volume of liquid flows through,often failing to detect micro-leaks in a timely manner.Liquid leak sensing cables extend leak detection from a point to a line,but they still require a substantial amount of liquid to flow through the cable to trigger an alert.Existing smart fabrics further extend leak detection from lines to planes,enabling real-time detection of micro-leaks of conductive liquids as low as a single drop(0.05 mL).Despite this advancement,they cannot provide feedback on the location of the leak.For detecting the location of leaks,there are two primary methods:continuous localization and zonal localization.Although the accuracy of zonal localization is lower than that of continuous localization,in practical use,it is a low-cost and practical solution to first identify the area where the micro-leak is located(usually with meter-level accuracy)and then manually conduct further detection and handling.The main challenge of zonal localization is to achieve more zoning with as few output wires as possible.This paper designs a smart fabric for detecting and locating conductive liquid micro-leak.The fabric features 2 n conductive warp yarns along its edges,each warp yarn making contact with the densely arranged conductive weft yarns on the fabric.The warp yarns are further interwoven to form n^(2) detection combinations,corresponding to n^(2) regions along the warp direction of the fabric.By scanning the on/off status of these detection combinations,the location of the leak can be identified.The number of regions formed by these warp cross-combinations,which is n^(2),is significantly greater than the 2 n-1 regions formed by conventional combinations.In this study,a smart fabric with six conductive warp yarns was prototyped.Slices of the fabric were prepared for structural observation,and a dedicated circuit was set up for electrical testing.A drip test was con
