[Abstract]:With the development of science and technology, smart textiles, as a new type of textiles, have attracted people's attention. The preparation of textile sensors with textile structure is an important field of new intelligent textile research. As the main material of flexible sensor, conductive fiber has important application in intelligent textile field. Firstly, the theoretical model of wearable capacitive fabric sensor is analyzed in this paper. Based on the theoretical analysis, the structure of the sensor is designed and developed. In the research progress of the preparation and performance of capacitive fabric sensor, the fabrication process of wearable capacitive fabric sensor is as follows: spinning of conductive cored yarn with multicomponent leather core structure, changing yarn fineness, yarn raw material, In this experiment, 16 groups of yarns of different specifications were spun; sizing yarn, equipped with a certain concentration of sizing material, sizing the spun yarn; weaving, by changing the yarn raw material, fabric area in the weaving process, The yarn materials are polyester / stainless steel yarn, polyester / copper wire, cotton / stainless steel wire, cotton / copper wire, cotton / stainless steel wire, cotton / copper wire, cotton / stainless steel wire, cotton / copper wire, cotton / stainless steel wire, cotton / copper wire respectively. The fabric area is 15 cm 2, 20 cm 2, 25 cm 2, 30 cm 2, the warp density of the fabric is 240 / 10 cm ~ (-1) 300 / 10 cm ~ (-1) 320 / 10 cm ~ (10) / 400 / 10 cm, the yarn fineness is 25 textures, 33 textures, 40 textures, 47 Tex, and a total of 64 capacitive fabric sensor samples under different processing conditions. The capacitance values of capacitive fabric sensors were tested at the frequency of 100Hz / 120Hz / 100Hz / 10kHz and the continuous pressure. The properties of the capacitive fabric sensors were tested and characterized. The performance test results of wearable capacitive fabric sensor show that yarn raw material, fabric area, fabric warp density and yarn fineness have certain influence on the performance of single layer capacitive fabric sensor in weaving process of capacitive fabric sensor. The rules are as follows: with the increase of fabric area, the capacitance value of capacitive fabric sensor increases as a whole; with the increase of fabric warp density, the capacitance value of capacitive fabric sensor increases as a whole; with the increase of yarn fineness, The capacitance value of capacitive fabric sensor shows a downward trend in general. With the increase of testing frequency, the capacitance value of capacitive fabric sensor is also decreasing, and the capacitance value of capacitive fabric sensor is the largest when the test frequency is 100 Hz; with the increasing of external pressure, the capacitance value of capacitive fabric sensor increases gradually. The capacitance of capacitive fabric sensor increases slowly as a whole. Cotton fabric sensors have a higher capacitance than polyester fabric sensors. The purpose of this paper is to study wearable capacitive fabric sensor with the best performance, which has certain theoretical and practical application value for the development of wearable capacitive fabric sensor.
