Electrocerebral electrode

Abstract

The invention provides an electrocerebral electrode. The electrode comprises a main body, reference electrodes, grounding electrodes and signal electrodes, wherein the main body comprises nose pads and a support, and can be worn on the head of a user; the hose pads can be worn basically symmetrically on the nose of a user, and the support can be worn behind ears of the user; the reference electrodes are arranged on one sides of the nose pads; the grounding electrodes are arranged on the other sides, opposite to the reference electrodes, of the nose pads; and the signal electrodes are arranged at tail ends of the support, and are contacted with mastoids behind the ears when the electrocerebral electrode is worn. The electrocerebral electrode is convenient and comfortable to wear, can be used for a long time, and does not influence normal lives.

Description

technical field [0001] The invention relates to an electroencephalogram electrode, in particular to an electroencephalogram electrode used for electroencephalography (Electroencephalography, EEG) measurement. Background technique [0002] At present, the electrode caps for EEG measurement usually use mesh or cloth materials with certain elasticity, and the electrodes are fixed on the caps according to specific positions. This kind of electrode cap design has the following disadvantages. [0003] Complicated wearing: The traditional EEG electrode cap needs to be worn with the assistance of a professionally trained operator, and conductive paste is injected into the electrode. It usually takes 40-60 minutes for an experienced operator to complete the wearing and adjustment of the electrode cap, and the operation process is complicated and time-consuming. [0004] Low comfort: Traditional EEG electrode caps will cause pressure on the user's head due to the constraints of elas...

Problems solved by technology

[0003] Complicated wearing: The traditional EEG electrode cap needs to be worn with the assistance of a professionally trained operator, and conductive paste is injected into the electrode

It usually takes 40-60 minutes for an experienced operator to complete the wearing and adjustment of the electrode cap. The operation process is complicated and time-consuming

[0004] Low comfort: Traditional EEG electrode caps will cause pressure on the user's head due to the constraints of elastic materials, which will cause discomfort to the user's head after long-term use

At the same time, the conductive paste will make the user's hair sticky, and even agglomerate after long-term use. The user needs to wash the hair after the test

[0005] Cannot be used in daily life conditions: Traditional EEG electrode caps are designed for clinical and scientific research applications. Due to their complicated wearing, limited use time of liquid conductive paste, complicated cable winding and inconvenient carrying, etc., they cannot be used in daily life. It is easy to use under certain conditions, which greatly limits the application range of EEG measurement
