Suppressing motion artifact graphene flexible ECG dry electrode

Abstract

The invention is a graphene flexible electrocardiogram dry electrode for suppressing motion artifacts, which is composed of a base layer, a fabric conductive layer, a motion artifact suppressing layer, a contact surface layer and an insulating shielding layer, wherein the flexible fabric constitutes the base layer The conductive cloth constitutes the conductive layer of the fabric; the first buffer layer, the reinforcing layer and the second buffer layer constitute the motion artifact suppression layer, the conductive sponge constitutes the first buffer layer and the second buffer layer, and the conductive cloth constitutes the The strengthening layer; the graphene coating constitutes the contact layer; the central hollow insulating fabric constitutes the insulating shielding layer. The invention is a dry electrode, which overcomes the irritation and damage to the skin caused by the traditional wet electrode, is non-disposable, and can be worn and used for a long time.

Description

technical field [0001] The invention belongs to the field of medical equipment (apparatus) / electrocardiogram electrodes, in particular to a graphene flexible electrocardiogram dry electrode for suppressing movement artifacts. Background technique [0002] In today's society, heart disease is the number one killer of human health. 1 / 3 of the world's population deaths are caused by heart disease, while hundreds of thousands of people die of heart disease every year in my country. Heart disease is the most likely disease in cardiovascular and cerebrovascular diseases to endanger the health and life of middle-aged and elderly people. Long-term and dynamic observation of early and sudden heart disease to capture short-term non-sustained abnormal ECG changes, especially transient arrhythmia and transient myocardial ischemic attack symptoms, which are useful for diagnosing heart disease, judging curative effect and Saving lives is critical. [0003] According to whether conducti...

AI Technical Summary

Problems solved by technology

At present, the disposable conductive gel wet electrode is commonly used in medical treatment to detect ECG. The disadvantage of the wet electrode is that its preparation is complicated, and the conductive gel gradually dries with time, causing measurement errors, easily causing skin allergies, and affecting comfort. Not suitable for long-term monitoring

Graphene is the best conductive material, but there is a contact resistance between graphene and the metal electrode, which cannot effectively improve the conductivity of the electrode

The patent also makes no mention of being able to detect EEG or suppress motion artifacts in dynamic situations
