The invention provides a flexible fabric sensor, which comprises a first conductive layer comprising a plurality of first electrodes arranged along a first direction; a second conductive layer comprising a plurality of second electrodes arranged in the second direction, and the first direction is perpendicular to the second direction; and a piezoresistive sensitive layer as a middle layer located between the first conductive layer and the second conductive layer, wherein the piezoresistive sensitive layer is formed by blending and weaving pressure-sensitive yarns and first creep-resistant fibers. According to the technical scheme, the piezoresistive sensitive layer is optimized, the piezoresistive sensitive layer is formed by mixed spinning of the pressure-sensitive yarn and the creep-resistant fiber, the spinning mode is a plain spinning mode, when external force is applied to a detected point, due to the fact that the creep characteristic of the creep-resistant fiber is very small, the creep-resistant fiber plays a role in supporting a stress beam, and deformation creep output by the piezoresistive sensitive layer is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of flexible sensors, in particular to a flexible fabric sensor. Background technique [0002] The flexible fabric sensor in the prior art adopts the upper, middle and lower three-layer structure form, see figure 1 Textile sensor structure, respectively: 1'-first conductive layer (top layer), 4'-sensitive material layer (middle layer), 2'-second conductive layer (bottom layer), the formed 3'-longitude and weft cross sensitive point, the equivalent resistance. [0003] Usually, the electrode uses a conductive material with a relatively large area, usually a round or a square surface electrode. [0004] The Mechanism of Measuring Pressure Variation by Resistive Fabric Sensor [0005] For resistive sensing textiles, when an external force is applied, the internal resistance of the yarn changes or the contact resistance between the yarns changes, which can cause a change in the measured resistance. Contact re...
