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 method and a device for preparing a tattoo type substrate-free electrode based on multilayer graphene. The method comprises the following steps of preparing a graphene oxidesolution; dropwise adding the graphene oxide solution onto a tattoo substrate, so that a graphene oxide film is formed after the graphene oxide solution is volatilized on the tattoo substrate; reducing the graphene oxide film by laser to form a graphene electrode pattern; peeling the unreduced graphene oxide film by a water solution; removing the tattoo substrate to generate the tattoo type substrate-free electrode. The method has the advantages that a universal substrate layer of a traditional flexible electrode is removed; a full-graphene electrode is directly used; the resistance between the electrode and the skin is reduced; signals such as electrocardio, electroencephalography and myoelectricity of a user can be observed in real time by using modules of electrocardio, electroencephalography, myoelectricity and the like.

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 substrate-free 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. To understanding. 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 commercial Ag / AgCl wet electrode proposed in the related art may cause allergic reactions or pain and itching due to the interaction between ions and the skin. At the same time, the electrode has shortcomings in term...
