Description

Technical Field

[0001] The present disclosure relates to the technical field of electroencephalogram (EEG) signal detection, and in particular to an EEG electrode. Background Art

[0002] The traditional electrodes mainly include: disc-shaped metal electrodes, metal / rubber dry electrodes (can be needle-shaped / claw-shaped / plane-shaped, among which claw-shaped electrodes can be Figure 1 shown) and gel electrodes.

[0003] Among them, the disc-shaped metal electrode needs to be used with conductive paste and is usually used in scientific research or medical scenarios. The operation is relatively complicated, and the user needs to wash their hair after use. Among them, dry electrodes have various shapes and styles. The hairless area usually adopts a flat contact surface shape; the hair area electrode is usually designed as a cylinder with needle-shaped or claw-shaped array contacts; the array contacts are used to penetrate the hair. The longer the contact, the better the penetration effect, but it will also cause more severe pain and safety risks. Among them, the gel electrode combines the advantages of conductive paste and dry electrodes. The conductivity is better than the dry electrode and the hair does not need to be washed after use. However, the service life of the gel electrode is extremely short, usually only a few hours, so it needs to be replaced frequently and carefully stored, which cannot meet the needs of daily product use.

[0031] The defects in the prior art are the results obtained by the inventor after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure for the above problems below should be the contributions made by the inventor to the present disclosure during the disclosure process.

[0032] like Figure 2 、 3 As shown in FIG4 , the present disclosure provides an EEG electrode, comprising: an electrode base 1 and at least one hair-moving member 2;

[0033] The hair moving member 2 is arranged on the lower side of the electrode base 1;

[0034] The hair moving member 2 is used to gather the hair in the target EEG signal collection area to expose the scalp in the EEG signal collection area.

[0035] The scalp is exposed for EEG signal collection. EEG signals can be collected using a separate EEG signal collection component, a hair-pulling component 2, or a combination of a separate EEG signal collection component and a hair-pulling component 2 having EEG signal collection functionality. Specifically, the EEG electrode may include at least one EEG signal collection component 4 disposed on the underside of the electrode base 1; the EEG signal collection component 4 is configured to cooperate with the corresponding hair-pulling component to form contact with a first scalp area exposed after the hair-pulling component has gathered hair, thereby collecting EEG signals. Specifically, the hair-pulling component 2 may include an EEG signal collection portion configured to form contact with a second scalp area exposed after the hair-pulling component has gathered hair, thereby collecting EEG signals. Specifically, the hair-pulling component 2 may be configured to gather hair using the hair-pulling portion of the hair-pulling component 2, whereupon the EEG signal collection portion of the hair-pulling component 2 comes into contact with the exposed scalp.

[0036] Among them, the hair-moving component 2 and the EEG signal collecting component 4 can be made of metal, rubber, plastic and other materials, and can be selected according to the usage scenario and the different functions of the hair-moving component 2 and the EEG signal collecting component 4.

[0037] The present disclosure provides an EEG electrode, comprising an electrode base and at least one hair-moving member disposed on the underside of the electrode base. The hair-moving member is used to gather hair in a target EEG signal collection area, exposing the scalp in the EEG signal collection area. Specifically, the hair-moving member gathers the hair, exposing the scalp area and avoiding the pain and safety risks associated with needle- or claw-shaped electrodes piercing the hair. Furthermore, gathering the hair with the hair-moving member allows the EEG signal collection member to establish sufficient and effective contact with the exposed scalp, improving the accuracy of EEG signal detection.

[0038] The present disclosure provides a possible implementation method, wherein the hair-moving member is V-shaped, or may be any other shape that can achieve the function of gathering hair in the target EEG signal collection or detection area and exposing the scalp area. The front end of the V-shaped hair-moving member is designed with an arc, thereby avoiding the dangers of using a sharp front end.

[0039] The present disclosure provides a possible implementation method, in which the rear end of the V-shaped hair-moving member 2 is connected to the electrode base and cooperates with the electrode base to form a hair-gathering area. Specifically, the hair-moving member 2 can have two contact points with the electrode base; the front end of the hair-moving member is used to contact the hair and gather the hair into the hair-gathering area.

[0040] The present disclosure provides a possible implementation. One side of the contact end of the hair deflecting member 2 and the electrode base 1 has a certain concave arc for gathering hair, so that the hair passing through the V-shaped tip can be stably gathered, avoiding hair slippage during use and affecting the accuracy and efficiency of collection.

[0041] The present disclosure provides a possible implementation. The connection point of the electroencephalogram signal acquisition member 4 and the electrode base 1 is located between the two contact points of the hair deflecting member 2 and the electrode base 1, so as to ensure that after the hair is gathered to the hair gathering area by the hair deflecting member 2, the corresponding scalp can be fully exposed.

[0042] The present disclosure provides a possible implementation. There are at least two hair deflecting members 2, and each hair deflecting member is sequentially connected into a wavy shape. Exemplarily, as Figure 2 、 Figure 3 shown, there are three hair deflecting members 2. As Figure 3 shown, the 3 hair deflecting members are sequentially connected into a wavy shape. Among them, there may be a certain interval between adjacent hair deflecting members, or they may be connected (as Figure 3 shown, connected by the connection point 3 of the hair deflecting member). Among them, the hair deflecting member 2 can also adopt other shaped arrangements.

[0043] The above-described embodiments are part of the embodiments of the present disclosure, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope protected by the embodiments of the present disclosure.
