FIELD OF TECHNOLOGY

A utility model in the form of an electrode device for transmitting an electrical signal and registering bioelectric potentials of areas of the human skin surface refers to the means of one-piece and non-separable electrical connections that provide electrical contact of areas of the human skin surface at the points of registration of bioelectric potentials with electronic devices that perform the functions of measuring and coding electrical signals bioelectric potentials of human skin surface areas.

The electrode device is designed to transmit an electrical signal of bioelectric potential from a specific area of the human skin surface to an electronic device, which converts the electrical signal from analog to digital form, and forms a data array for further processing in electronic computers.

LEVEL OF TECHNOLOGY

A device is known that performs the functions of electrical switching, containing textile-like flexible conductive electrodes connected to an external circuit, and a textile-like element with variable resistance, capable of exhibiting a change in electrical resistance during mechanical deformation and made in the form of a coating applied to textiles sandwiched between said electrodes (patent RF No. 2273911, IPC H01H 3/14, H01H 13/16, H01H 1/021, H01H 13/00. Published on 2006.04.10. Bull. No. 10).

The specified device contains flexible electrodes, can be used to control electronic equipment, but it is not intended for contacting electrically conductive elements with human skin. Features of this device:

- the presence of a variable electrical resistance in this device;

- electrically conductive elements are made in the form of conductive yarn woven, knitted or sewn into non-conductive textiles.

Also known is a composite electrical contact made of a material containing a carbon base and metal silver additives, in which the carbon base is made of carbon fiber, and metal additives are distributed on the surface of the carbon fiber in the form of a coating (RF patent No. 176664, IPC H01H 1/021, H01H 9/00 Published 25.01.2018 Bull. No. 3).

The limitation of this device is that it belongs to electrical engineering, for example, to materials used for the manufacture of electrical contacts of low-voltage equipment. It can be used in electromagnetic relays, for signaling, centralization and blocking devices in railway transport, but is not intended for use as electrode systems for measuring and recording bioelectric potentials of human skin.

The task of the developed utility model is to create an electrode device suitable for use as part of clothing items and intended for transmitting electrical signals of bioelectric potentials of human body skin areas to measuring devices.

The technical result of this utility model is to obtain on the fabric of the elements of clothing a system of electrodes of arbitrary configuration, which has the property of elasticity, which allows the specified system of electrodes to change its size and shape in accordance with the applied mechanical forces, as well as to take the shape of the surface of the human body in places of contact with the surface human skin.

USEFUL MODEL DISCLOSURE

To form an electrode device, an adhesive composition is used with the addition of nanosilver particles to it in an amount sufficient to form an elastic electrically conductive element of arbitrary shape in the form of a strip of dried adhesive composition with a thickness of no more than 1-2 mm, firmly adhered when the said adhesive composition is dried. with a base material, which can be, for example, the fabric of a garment.

The application of the electrode device on the fabric of a garment is carried out by silk-screen printing or screen printing, or by transferring a pattern from a polymer base to the fabric of a garment with subsequent drying, for example, using infrared radiation sources or drying ovens. The shape of the elastic electrically conductive elements of the electrode device can be arbitrary and is determined by the configuration of the open sections of the stencil or by the pattern of the elements of the electrode device in the process of transfer transfer.

The physical and mechanical characteristics of the adhesive composition used as a structural basis for the elements of the electrode device make it possible for it to acquire elastic properties after drying, which allows each electrode individually and the electrode device as a whole to change its size and shape in accordance with the applied mechanical forces, as well as to take the shape of the surface of the human body at the location of the electrode device on the body.

Electrical contact of the electrodes with the human skin surface is carried out only in the area of the contact pads made in the form of conical projections. To prevent the rest of the electrodes from contacting with human skin, the entire surface of the electrodes, except for the area of the contact protrusions, is covered with a dielectric material.

Thus, the electrode device forms a contact group consisting of two or more electrodes of arbitrary shape, each of which is in contact with the human skin surface with one end in the form of a conical protrusion, and the other end is electrically and mechanically connected to a detachable contact group, which provides an electrical connection with an electronic device that measures and encodes an electrical signal of the bioelectric potential of human skin surface areas.

Electrical contact of the electrode device with the human skin surface in the area of the contact protrusions is carried out without moistening with liquids and using additional substances that help to reduce the electrical resistance of the electrode-skin contact.
