In recent years, driven by materials science, electronics and nanotechnology, wearable devices have made significant progress, especially in flexible materials, biocompatibility and multifunctional integration. Wearable devices require flexible sensors, which are sensors that can maintain performance under external forces such as bending, twisting or compression. They are usually composed of flexible substrate materials and sensitive materials and are suitable for wearable devices, medical health monitoring, robotics and other fields. Existing flexible sensors mainly include a base layer and a conductive layer printed thereon, wherein the conductive layer is mostly forked electrodes, and the forked electrodes are mostly printed by screen printing. The existing printing is horizontal, and it is difficult to ensure that there is sufficient slurry on each printing part, resulting in uneven printing. The quality of the forked electrodes formed is not high, which damages the conductive effect and reduces the sensing effect.
