Fig. 1 is a schematic structural view of a wearable electrode cap according to an embodiment of the present invention. As shown in fig. 1, the wearable electrode cap according to the embodiment of the present invention includes: a cap 11 which is elastic, non-conductive and non-magnetic material permeable to gas, an electrode 20 provided on the cap 11, and a lead wire 22 for connecting the electrode 20 to an external signal source.

In order to make the whole surface of the electrode 20 fully contact the head skin of the wearable electrode cap user, the invention provides a conductive coating 31 on the electrode 20. The conductive coating 31 may be a conductive paste, grease, or an oily conductive coating of a poorly flowable material having a resistivity of not more than 200K Ω · M.

FIG. 2 is a schematic diagram illustrating the principle of applying an electrical signal to an electrode according to an embodiment of the present invention. As shown in fig. 2, the electrical signal flows from one output terminal of the signal source, is applied to the conductive layer 21 of the electrode through the conducting wire 22, is applied to the scalp through the coupling medium 23 and the conductive coating 31, passes through the skull and the brain tissue, reaches the scalp of the symmetrical plane, and returns to the other output terminal of the signal source through the electric coating 31 of the symmetrical plane, the coupling medium 23, the conductive layer 21 and the conducting wire 22, thereby completing the application process of the electrical signal.

Fig. 3 a-3 e are schematic views of the cap structure according to the embodiment of the invention. As shown in FIG. 3a, the electrode 20 is provided on the cap 11, the surface of the electrode 20 contacting the scalp slightly protrudes from the inner surface of the cap 11, and when the user wears the cap 11, one surface of the electrode 20 is attached to the scalp. Because the electrode 20 obtains a pressure 17 towards the scalp by the elasticity of the cap body under the action of the elasticity 16 of the cap body, the surface of the electrode 20 attached to the scalp is firmly pressed on the surface of the scalp by the pressure 17 formed by the elasticity of the cap body.

The cap body 11 is made of an elastic non-conductive and non-magnetic material, such as rubber, silicon rubber or textile material, and has a good air permeability or a design structure with ventilation and air permeability, so as to ensure the comfort after wearing. Illustratively, the cap 11 may have a net structure as shown in fig. 3b, a knitted structure as shown in fig. 3c, and a frame structure as shown in fig. 3d and 3 e.

As shown in fig. 4a, in this example, the electrodes 20 comprise at least one pair of current electrodes. The external signal source comprises a current source. The conductive layer 21 of the current electrode is connected to a lead 22, one side of which is in contact with the scalp 10, and current is passed from the lead 22 to the conductive layer 21 of the electrode and then applied to the scalp from the other side of the conductive layer 21, completing the process of applying current to the head.

As shown in fig. 4b, in this example, the electrodes 20 comprise at least one pair of electric field electrodes. One surface of the conducting layer 21 of each pair of electric field electrodes is connected with the lead 22, the other surface is tightly combined with one surface of the coupling medium 23, the other surface of the coupling medium 23 is contacted with the scalp, and the external signal source is a voltage source. The alternating current signal flows from the lead 22 to the conductive layer 21 of the electrode, because the coupling medium layer 23 has a high dielectric constant (dielectric constant/thickness of the coupling medium layer is greater than or equal to 3000, wherein the thickness unit of the coupling medium layer is mm), the scalp 10 has a conductive characteristic, the conductive layer 21, the coupling medium 23 and the scalp 10 can be equivalent to a capacitor, the capacitor has the functions of alternating current connection and direct current isolation, and the alternating current signal can be smoothly applied to the scalp 10 through the coupling medium 23.

As shown in fig. 4c, in this example, the electrode 20 comprises at least one magnetic field electrode. When current passes through the coil 24, magnetic lines of force 26 in different directions are generated at the winding center of the coil 24 according to different directions of the current entering the coil 24, and when the winding center of the coil is made of high-permeability material, the magnetic lines of force 26 are mainly concentrated in the high-permeability material, so that the magnetic lines of force can be concentrated to generate a stronger magnetic field.

As shown in fig. 4d, in the present example, the electrode 20 comprises at least one electromagnetic wave electrode. The conductive layer 21 of each electromagnetic wave electrode is connected to a wire 22, one of which is provided with an insulating layer 25. The insulating layer 25 is provided between the scalp 10 and the conductive layer 21, and maintains the insulation between the conductive layer 21 and the scalp 10. Signals flow from the lead wires 22 to the conductive layer 21 of the electrode, and since the conductive layer 21 has a certain area, the signals are radiated from the surface of the conductive layer 21 to the head to form electromagnetic radiation waves 27, and the scalp 10 is closer to the conductive layer 21, and the electromagnetic waves 27 are applied to the head.

In the embodiment of the present invention, the cap body 11 is worn on the head, and the electrode 20 is provided on the cap body 11. The arrangement of the electrodes 20 on the cap 11 includes a fixed type and a movable type.

Wherein, the fixed type is the electrode cap customized for the user according to the actual treatment requirement. The electrodes are arranged at fixed positions of the cap body 11, the number and the positions of the electrodes 20 do not need to be adjusted by a user, a new electrode cap needs to be customized when a treatment plan needs to be adjusted, and the user can simply clean the electrodes 20 and the cap body 11.

The movement, i.e. the position where the electrode 20 is mounted on the cap 11, is adjustable. Before use, the electrodes 20 are arranged on the cap body 11 according to the treatment plan according to the quantity and distribution requirements. When the treatment plan is adjusted or the cap body 11 needs to be cleaned, the electrode 20 is detached from the cap body 11, and when the electrode 20 is used again, the electrode 20 is attached to the cap body 11 according to a new treatment plan, or the electrode 20 is attached to the original position again after the cap body 11 is cleaned.

As shown in fig. 5a, in this example, one surface of the electrode 20 and the inner surface of the cap 11 are adhered together by an adhesive 40 for fixing the electrode, and the other surface is attached to the scalp after the user wears the cap 11.

As shown in fig. 5b, in this example, the cap body 11 printed by 3D reserves a structure for mounting the electrode 20, the slot 41 of the electrode 20 is clamped at the reserved position of the cap body 11, the cap body 11 is provided with an air hole for ventilation, and the electrode can be taken down when the cap body 11 is cleaned.

As shown in fig. 5c, in this example, the inner surface 43 of the cap body has characteristics similar to those of the soft surface 45 of the hook and loop fastener, one surface of the electrode 20 is in contact with the skin, and the hook and loop fastener surface 44 is attached to the other surface, so that the hook and loop fastener surface 44 can be more firmly attached to any position in the cap body 11. When the user wears the cap body, the electrode 20 is attached to the scalp and is in good contact with the scalp under the action of the elasticity of the cap body 11 and the conductive smearing matter.

In addition, the skilled person can select to fix the electrode 20 on the cap body 11 by sewing, button, snap fastener, etc. according to the requirement, or can form the whole electrode array and fix the electrode array on the inner surface of the cap body 11 by sticking, magic tape, snap, sewing, button, snap fastener, etc.

The conductive coating 31 is applied between the electrode 20 and the scalp 10, and the problem of poor contact between the electrode 20 and the scalp 11 is solved. Because the heads of the wearers are different in size and irregular in shape, the surface shapes of all parts are very different, and the electrode 20 with a fixed shape is difficult to be matched and contacted with the scalp surfaces of all the wearers well, a layer of conductive coating 31 is coated on the electrode 20, and then the electrode cap is worn, so that the contact condition of the electrode 20 and the scalp is greatly improved.

Fig. 6 a-6 b are schematic views illustrating the effects of the conductive coating according to the embodiment of the invention. As shown in fig. 6a, there is a partial area of poor contact between the electrode 20 and the scalp 10 to form a gap 30, so that the contact between the electrode 20 and the scalp 10 is poor. As shown in fig. 6b, the conductive coating 31 fills the gap 30, and the conductive coating 31 has a resistivity close to that of the scalp and is equivalent to that of the scalp, thereby ensuring good contact between the electrode 20 and the scalp 10. Due to the effect of metabolism, a plurality of dead skins exist on the skin, the resistivity of the dead skins is higher, the contact effect can be influenced, and the influence caused by the dead skins can be reduced after the conductive smearing matter is smeared on the skin.

In one embodiment of the present invention, the cap body 11 is provided with a mark for determining the mounting position of the electrode 20 on the cap body 11.

FIG. 7 is a schematic diagram of a coordinate line set on a cap body according to an embodiment of the invention. As shown in fig. 7, the weft and warp divide the surface of the cap body 11 into several regions, each of which can be expressed in terms of a position by a weft code and a warp code, and also can be expressed in terms of a number to facilitate the mounting of the electrode 20 at a designated position on the cap body 11.

In one embodiment of the present invention, the cap body 11 is provided with a positioning mark for identifying a wearing direction and a wearing position of the cap body 11.

FIG. 8 is a schematic view of positioning marks on a cap in accordance with an embodiment of the present invention. As shown in fig. 8, the positioning mark is a mark for identifying the wearing direction and position of the cap body, which is drawn at a position where the cap body has a directional meaning. Taking the example of drawing the arrow-shaped pattern right in front of the cap body 11, when the user wears the wearable electrode cap of the present invention, the arrow mark right in front of the cap body 11 is aligned with the eyebrow center of the wearer, i.e., the wearing direction is correct; the marks on the two sides of the cap body are close to the two ears, namely the correct wearing depth.

Fig. 9 is a schematic view of an intracranial electrically-created environment in an embodiment of the invention. As shown in fig. 9, taking an example in which a pair of electric field electrodes are respectively applied to the front and rear portions of the head of a wearer, an external electric signal is connected to the conductive layer 21 through the lead 22, then applied to the scalp through the coupling medium 23 and the conductive paste 31, passes through the skin, the skull, and the brain tissue, and then reaches the opposite skull, skin, conductive paste, coupling medium, conductive layer, and lead to form a loop of the electric signal, the electric signal forms an electric environment in the cranium, and the direction and intensity of the electric line of force 28 change accordingly with the change of the direction and intensity of the externally applied electric signal.
