Dry electrode and physiological multi-parameter monitoring equipment

A non-disposable/reusable dry electrode, comprising an encapsulation, extraction electrode and a contact surface layer, wherein the extraction electrode and the contact surface layer are disposed in the encapsulation;

• the encapsulation comprises a first surface and a second surface, the extraction electrode being exposed on the second surface and connected with the contact surface layer, and a glue layer being disposed on the first surface;
• the contact surface layer comprises an exposed part and an embedded part, the embedded part being disposed in the encapsulation, and the exposed part being exposed on the first surface;
• the glue layer is provided with an contact surface hole corresponding to the exposed part in position;
• and the exposed part is provided with a positioning surface for quick adhesion with the glue layer;
• preferably, a material of the contact surface layer is conductive silica gel;
• further preferably, a surface of the exposed part of the contact surface layer is provided with protruded textures, and a groove is formed between the adjacent textures, preferably, conductive filling materials of the conductive silica gel are nickel-coated copper powder and conductive graphite;
• preferably, the encapsulation is configured to be a flexible insulating encapsulation;
• preferably, the extraction electrode is selected from one of the followings:
• a metal joint vertically disposed on the second surface, an outgoing wire horizontally disposed on the second surface, and an electrode interface horizontally disposed on the second surface.
