Anti-interference graphene electrocardio-electrode and preparation method thereof

Abstract

The invention discloses an anti-interference graphite electrocardio-electrode and a preparation method thereof. When the electrocardio-electrode is prepared, reduced graphene oxide is firstly prepared and compounded with polyurethane resin, graphene is subjected to gamma-aminopropyltriethoxysilane surface treatment, a hydroxyl group is introduced and reacts with isocyanate in the polyurethane resin, so crosslinking is generated, and the conductivity of a fiber membrane is improved; meanwhile, a reduced graphene oxide layer is sprayed on the surface of the fiber membrane, so numerous conductive channels are formed, and efficient transportation of electrons is guaranteed; and since impedance between human skin and graphene is large, impedance between the graphene and the skin is reduced due to the fact that the multiple layers of fiber membranes are compounded with the reduced graphene oxide layer, and the anti-interference capacity of the electrode is improved. The electrocardio-electrode prepared by the invention has good conductivity and anti-interference performance, is reduced in the contact impedance with the skin and more accurate in measurement, and has good practicability and industrial value.

Description

technical field [0001] The invention relates to the technical field of ECG electrodes, in particular to an anti-interference graphene ECG electrode and a preparation method thereof. Background technique [0002] According to the statistics of the World Health Organization, at present, cardiovascular disease is the largest cause of human death in the world. About one-third of the global death population is caused by cardiovascular disease. Cardiovascular disease has been closely related to our life, body and mind. Health is closely related, and this disease can be detected and diagnosed in advance, and the electrocardiogram is an effective way to diagnose the disease. [0003] The ECG electrode is an indispensable device for detecting the ECG. It can accurately measure the ECG signal of the human body. Once the ECG electrode cannot accurately measure the ECG signal of the human body, it is impossible to accurately know whether there is a cardiovascular disease. Disease, whic...

Problems solved by technology

[0003] The ECG electrode is an indispensable device for detecting the ECG. It can accurately measure the ECG signal of the human body. Once the ECG electrode cannot accurately measure the ECG signal of the human body, it is impossible to accurately know whether there is a cardiovascular disease. disease, which means we may miss the best time for treatment

[0004] At present, the most common ones on the market are electrocardiogram electrodes and conductive silver paste made of silver, and the contact impedance between silver and the human body is relatively large, resulting in inaccurate measurement, and prolonged use may cause adverse effects on human skin. , based on this, the present invention proposes an anti-interference graphene ECG electrode and its preparation method to solve the above problems
