Background
Electroencephalography (EEG) is a method of recording brain activity using electrophysiological markers, in which post-synaptic potentials generated in synchronization with a large number of neurons are summed up during brain activity. It records the electric wave change of brain activity, which is the overall reflection of the electrophysiological activity of brain nerve cells on the surface of cerebral cortex or scalp; clinical practice shows that brain waves contain a large amount of physiological and disease information, so that the basis can be provided for disease identification through processing the brain waves; the measurement of brain waves is commonly performed by electroencephalogram (EEG) detection, in which patterns obtained by recording spontaneous bioelectric potentials of the brain from the scalp by means of a precision electronic instrument in an amplified manner are recorded, and spontaneous and rhythmic electrical activities of brain cell groups are recorded by means of electrodes placed on the scalp in accordance with a certain rule.
In performing electroencephalography, it is necessary to place electrodes at specific locations on the scalp of a patient, these being provided in accordance with the 10-20 International electroencephalography system (Jasper,1958), established by the International society for electroencephalography in 1958. The principle of the 10-20 system is that the relative distance between the scalp electrode points is expressed in terms of 10% and 20%, and the method is characterized in that the electrode arrangement is proportional to the size and shape of the skull, and the electrodes are properly distributed in the main parts of the skull in standard positions. Since the electrodes need to be arranged on the scalp of the patient in a plurality of numbers, such as 21 leads, 23 leads or even more leads, the precise requirements on the arrangement and the position of the electrodes are required.
Existing methods of electrode wear have a number of problems in clinical use:

(2) A mesh electrode cap: the electrode is not easy to be fixed on the scalp, the traditional fixing method adopts an elastic net-shaped cap body which is sleeved on the head of a patient, the electrode is bound by the elasticity between the net-shaped cap body and the scalp of the patient, and even if the cap body is arranged according to specifications, the cross part of meshes of the cap body cannot completely cover the placing position of the electrode, so that the placing position of the electrode is not accurate; there is not location sign on the netted cap body again, because different patients 'age and head footpath are different, and electrode mounted position is inaccurate, still needs medical personnel to confirm the mounted position of electrode one by one according to patient's cranium appearance, and is very troublesome.
(3) Wear integral type electrode cap: medical personnel wear the electrode cap on the head of a patient, then inject the conductive paste at each electrode position, and reduce the contact resistance of each electrode and the scalp one by observing the impedance detection interface screen of the electroencephalogram acquisition software. Wearing the cap takes from 30 minutes to 60 minutes, which is particularly time consuming. The saline electrode cap produced by American company E needs to be soaked in saline, and the whole cap is worn on the head of a testee in a wet and percolating way, so that the discomfort of the testee can be caused, the mood fluctuation of the testee is likely to be induced, and the experimental result is interfered. The price of one electrode cap is about 2 ten thousand RMB, and the cost is higher. And the electrode cap produced by each company can only be matched with the amplifier produced by the company for use, and a specific interface standard is used. The electrode cap manufactured by company A cannot be directly connected with the amplifier of company B for use.
