Abstract

The invention discloses a method of magnetic field assistance laser processing for a biomedical electrodes and relates to a biomedical electrode. A copper sheet is adopted as an electrode material andclamped on a worktable, and laser beams generated by a fiber laser device pass through a laser galvanometer and a focusing lens in sequence and are focused on the surface of the copper sheet; materials in an illumination area can be melt or gasified and cause a recasting phenomenon, and after recasting, a microneedle array is formed on the surface of the copper sheet; acid pickling and alcohol leaching are conducted on the copper sheet to remove oxidation layers and impurities, a Ag / AgCl cladding layer is formed on the surface of a metal electrode core through electroplating, and that is to say that the metal electrode core with the microneedle array on the surface is obtained. A wire is bonded to the metal electrode core through a conducive silver adhesive and then penetrates through anelastic housing; medical proof fabric is used for binding the wire to the two sides of the elastic housing, and then the biomedical electrode with the microneedle array is formed at last.

Description

technical field [0001] The invention relates to a biomedical electrode, in particular to a method for magnetic field-assisted laser processing of a biomedical electrode. Background technique [0002] Biological organs and tissues have a very important type of physical and chemical changes in their life activities, which include potential and polarity changes, that is, bioelectricity, which is a basic feature of biological living tissues. In the research of modern medicine, the collection and measurement of bioelectricity is attached great importance, and the electrode system, as the front end of the bioelectricity collection system, is in direct contact with human skin, which affects the accuracy and stability of the entire measurement system. [0003] Current bioelectric collection equipment generally uses wet gel electrodes and metal plate electrodes: wet gel electrodes are widely used in medical testing and scientific research such as ECG and EEG because of their low nois...
