Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] Such as figure 1 As shown, the electrode types commonly used in related technologies include Ag / AgCl electrodes, dry electrodes, microneedle electrodes, or dry electrodes with insulators. Among them, Ag / AgCl electrodes commonly used in the market may have rejection reactions. Disadvantages such as not being comfortable enough to wear; traditional dry electrodes are not in close contact with the skin, and are generally made of hard metal, resulting in inconvenient and uncomfortable wearing; microneedle electrodes need to pe...

Abstract

The invention discloses a preparation method and apparatus of a tattoo-style electrode based on multilayer graphene, wherein the preparation method comprises the steps of preparing a graphene oxide solution; dropwise adding the graphene oxide solution to a tattooed substrate so that graphene oxide solution forms a graphene oxide film after the tattooed substrate volatilizes; reducing the grapheneoxide film through laser to form a graphene electrode pattern; stripping the non-reduced graphene oxide film through an aqueous solution so as to generate a tattoo-style electrode. The tattoo-style scheme is employed herein; the electrode pattern can be customized; tattoo-style electrode is attractive to wear, is barely felt by a wearer, never affects the daily life, and is suitable for observingthe user's electrocardiogram signals, electroencephalogram signals, electromyogram signals and the like in real time through an electrocardiogram module, an electroencephalogram module, an electromyogram module and other modules.

Description

technical field [0001] The invention relates to the technical field of biological electrodes, in particular to a method and device for preparing a tattoo-type electrode based on multilayer graphene. Background technique [0002] With the intensification of aging, how to better serve the elderly and understand the physical condition of the elderly anytime and anywhere has become an important social issue. At the same time, with the development of social economy, people hope to have a deeper understanding of their physical condition . ECG, EEG, EMG and other bioelectrical signals, as an important indicator of the human body, can reflect the physiological state of the human body and are the early signs of many diseases. [0003] The existing commercial Ag / AgCl wet electrodes have allergic reactions due to the interaction between ions and the skin, causing pain and itching, etc. At the same time, the electrodes have shortcomings in terms of long-term wear and aesthetics. Cont...
