Abstract

The invention provides a low-impedance electroencephalic sensing electrode device based on an independent circle-division cushioning structure. The device comprises an electrode head cover (10), a first cushioning spring (30), a second cushioning spring (40), a first reservoir unit, a second reservoir unit and electrode contact columns (90). The upper ends of the first cushioning spring (30) and the second cushioning spring (40) are fixed to the lower surface of the electrode head cover (10), while the lower ends of the first cushioning spring (30) and the second cushioning spring (40) are fixed to the reservoir units, and the springs are mounted in a coaxial mode, wherein the diameter of the second cushioning spring (40) is larger than that of the first cushioning spring (30); the electrode contact columns (90) are uniformly distributed below the reservoir units, wherein the electrode contact columns (90) are in inner communication. According to the device, the problem of the unstable contact between the electrode and a scalp and the motion artifact caused by the head jolt and vibration is effectively solved through the independent circle-division cushioning structure; through an automatic conducting liquid supplement and filling structure, the low-impedance property and the long-term continuous use of the electrode which is formed by the electrode contact columns are guaranteed.

Description

technical field [0001] The invention relates to the field of electroencephalogram sensing electrodes, in particular to a low-impedance electroencephalogram sensing electrode device based on an independent ring-divided buffer structure. Background technique [0002] Brain-computer interface can be widely used in the diagnosis, auxiliary treatment or rehabilitation of diseases such as movement disorders, Alzheimer's disease, epilepsy, stroke, etc., and improve the quality of life of patients with motor dysfunction diseases. For example, patients with motor dysfunction can control the movement of wheelchairs through their brain waves, thereby assisting themselves to walk. As the world population base continues to grow and the aging population continues to grow, the number of people suffering from Parkin's disease, Alzheimer's disease, epilepsy and other diseases will also continue to increase. The demand for the treatment of these diseases will also drive the continuous and ac...
