This study used the traditional textile industry screen printing as the main process and developed a kind of double-layer multi-channel elastic printing circuit device. The elastic conductive slurry was used as the basic conductive material and supplemented by the high elongation type structure design. In this study, the TPU membrane commonly used in the general textile field is selected, which has an immediate effect on the application of current textiles. In the future, the different designs can be made according to needs, effectively improving the efficiency of use per unit area, which will contribute to the electronic transmission of smart textiles.
