Abstract

The invention discloses a tattooing electrode and a preparation method and system thereof. The tattoo electrode comprises a conductive layer and transfer printing tattoo paper; the conductive layer comprises a conductor wrapped by a conductive polymer, the conductive polymer is a PEDOT: PSS material, and the conductor is a silver nanowire; the transfer tattoo paper comprises an adhesive layer, a dissolving layer and a supporting layer, the conductive layer is used to form an all-polymer electrode by inkjet printing an electrical conductor on the adhesive layer and the support layer. According to the tattooing electrode and the preparation method and system thereof, the conductive layer, the transfer printing tattooing paper and the magnetic attraction layer are arranged, and materials corresponding to all the layers are reasonably selected, so that the light transmission and the air permeability of the tattooing electrode can be enhanced by utilizing a silver nanowire material in a network shape; the tattoo electrode has the advantages that skin breathing is not hindered, the influence of sweat on brain signal transmission is reduced, the tattoo electrode has washability due to the non-hydrophilicity of the conductive polymer material, and brain signals can be stably recorded for a long time.

Description

technical field [0001] The invention relates to the technical field of biological electrodes, in particular to a tattoo electrode and a preparation method and system thereof. Background technique [0002] The tattoo electrode is a flexible, stretchable and ultra-thin electronic sensor device, which can fit on the human skin and record various electrophysiological signals of the human body with a high signal-to-noise ratio. It has great application prospects in the medical field. In 2017, the United States developed a graphene-based filamentous serpentine-shaped tattoo electrode, which has a high stretchability of 40%, an optical transparency of 85%, and its mesh structure can provide good air permeability. However, since the electrode is produced by chemical vapor deposition, the obtained graphene is relatively fragile, it is difficult to obtain the desired tattoo pattern and the durability is low. In 2018, France and Italy cooperated to develop a tattoo electrode for brai...
