Abstract：To investigate the effects of impregnation and silk-screen printing on hydrogel technology on the electrical conductivity of textile-based electrodes,three different structures including woven honeycomb,woven grid and"Tatami"embroidery techniques were selected to build fabrics in this pa-per.The variation of resistance in the flattening state and bending degree were tested experimentally,and the mechanism was analyzed in combination with the microstructure.The results show that the double layer of hydrogel is formed by the impregnation process,and the resistance value is increased by 4～49 times.The single layer of hydrogel was formed by the screen-printing process,and the re-sistance was significantly reduced,among which the honeycomb tissue electrode decreased by up to 64.8％.After the hydrogel treatment,the resistance difference along the warp and weft direction of the embroidery electrode was eliminated,and the resistance fluctuation of all electrodes under differ-ent bending and recovery states were significantly reduced,and the conductive stability was improved.The screen-printing process combined with hydrogel can effectively optimize the electrical properties of textile-based electrodes,and provide theoretical support for the design of textile-based electrodes in wearable devices.
