| titleOfInvention | Hydrogel electrode for long-term electroencephalogram acquisition and preparation method thereof |
| abstract | The invention provides a hydrogel electrode for long-term electroencephalogram acquisition and a preparation method thereof, wherein the preparation method comprises the following steps: a support frame for supporting the entire electrode; the conductive hydrogel structure is used for contacting with the skin to obtain a bioelectricity signal and is arranged on the bottom surface of the supporting frame; a conductive member for converting a bioelectric signal into an electronic current, one end of the conductive member penetrating into the inside of the support frame and having its end exposed to the upper surface of the support frame, the other end of the conductive member extending into the conductive hydrogel structure; and the metal snap fastener is used for connecting the conductive part with an external lead, is arranged on the supporting frame, is positioned above the conductive part and is in contact with the conductive part. The invention does not need to use conductive paste, has convenient installation, strong moisturizing performance, repeated use, low skin-electrode contact impedance and high signal acquisition quality, and is suitable for acquiring bioelectricity signals for a long time; the hair-free and soft pillow can be used in a hair area and a hair-free area of the head of a human body, and is high in flexibility and comfort. |
