Graphene flexible electrocardio dry electrode with effect of inhibiting motion artifact

Abstract

The invention provides a graphene flexible electrocardio dry electrode with an effect of inhibiting motion artifact. The electrode comprises a substrate layer, a fabric conductive layer, a motion artifact inhibiting layer, a contact surface layer and an insulation shielding layer, wherein the substrate layer is made of a flexible fabric; the fabric conductive layer is made of a conductive fabric; the motion artifact inhibiting layer is formed by a first buffer layer, a reinforcing layer and a second buffer layer; the first buffer layer and the second buffer layer are respectively made of conductive sponge; the reinforcing layer is made of the conductive fabric; the contact surface layer is formed by a graphene coating; and the insulation shielding layer is made of a center-hollow insulation fabric. The dry electrode can be used for overcoming irritation and damage of a traditional wet electrode on skin, is not a disposable electrode, and can be worn 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
