Description

Electrode patch

Field of the Invention [0002] The present invention relates to an electrode patch, and more particularly, to an electrode patch having a low electrical resistance for low resistance and high efficiency.

As the efforts to continuously monitor and record biological signals and make healthy living habits based on them have been continuing, bio-signal measurement and recording techniques that can be normally used by the general public are being steadily developed.

Electrocardiogram (ECG), which measures changes in cardiac muscle potential, is a typical example of this bio-signal. It not only monitors pulses and exercise in daily life, but also detects cardiovascular diseases such as angina, arrhythmia, and myocardial infarction can do.

Since the devices for measuring bio-signals detect electrical signals on the surface of the skin, the device should always be in contact with the skin, and stable signal detection should be possible even in the movement of the user.

Disposable electrodes (3M's RedDot ^TM, etc.), which are widely used at present, are composed of a metal electrode having improved conductivity by Ag / AgCl, an electrolyte or gel-type medium having electroconductivity, and a foam- do.

In addition, the electrode patch is attached to the joint or muscle area in the electric stimulation therapy apparatus which increases the basic metabolism by causing the weak electric power to the human body and exercising the muscle directly by stimulating the muscle to increase the muscle mass.

In the exercise using EMS (Electronic Muscle Stimulation) equipment, a specially made electric suit with electrode patch will be worn.

However, such a conventional electrode patch has a disadvantage that the current value is reduced by half because the resistance value is large and the electric resistance varies depending on the measurement position. Of course, it is possible to reduce the resistance by adding silver or carbon to the conductive material, but this also has a disadvantage that the cost is increased.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned disadvantages, and it is an object of the present invention to provide an electrode patch having a structure in which a resistance value is small and electrical resistance can be uniform regardless of a measurement position.

An electrode patch for achieving the object of the present invention comprises an electrode layer made of a conductive elastic material and formed of a silicon material, a support layer formed on one surface of the electrode layer to support and protect the electrode layer, A conductive layer formed between the electrode layer and the support layer to reduce an electrical resistance of the electrode layer and a connector connection member electrically connected to the electrode layer, wherein the conductive layer enhances the conductivity of the electrode layer, So that the surface resistance value is small and uniform.

In the electrode patch of the present invention, a conductive metal such as nickel or iron is bonded between an electrode layer made of a conductive rubber and a supporting layer made of silicon or the like to reduce resistance and have a high conductivity, so that more effective measurement and electric stimulation can be applied, Quality can be maintained.

In addition, bonding between the silicon and the conductive rubber, including voids in the conductive metal, ensures a firm adhesion between the silicone and the conductive rubber.

2 is an exploded perspective view showing an electrode patch according to the present invention,
3 and 4 are sectional views showing an electrode patch according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figs. 1 to 4 show a perspective view, an exploded perspective view, and a cross-sectional view, respectively, of an electrode patch according to the present invention.

1 to 4, the electrode patch 100 of the present invention includes an electrode layer 110 forming an electrode using a conductive elastic material, an electrode layer 110 formed on one side of the electrode layer 110, A conductive layer 120 formed between the electrode layer 110 and the support layer 130 to reduce the surface contact resistance of the electrode layer 110 and to uniformize the entire surface of the electrode layer 110, And a connector connecting member 140 connected to the connector.

The electrode layer 110 is made of conductive rubber and is formed in a structure that can be repeatedly attached to and detached from the skin.

In this embodiment, the electrode layer 110 is formed in a rectangular plate having a predetermined thickness. However, the electrode layer 110 may be formed in various shapes depending on the body part to be attached.

A conductive layer 120 formed of a conductive metal is bonded to one surface of the electrode layer 110, that is, the surface opposite to the skin attachment surface, thereby reducing the electrical resistance of the electrode layer 110 and ensuring uniform surface contact resistance as a whole.
The electrical conductivity is defined as the reciprocal of the resistivity and the resistivity is a characteristic of the metal. As the conductive layer 120 made of a conductive metal having a low resistivity is bonded onto the electrode layer 110, the surface resistance value of the electrode layer 110 is reduced.

Here, the conductive layer 120 is made of conductive metal such as nickel (Ni) or iron (Fe).

The support layer 130 is made of a nonconductive material such as silicon and is installed to protect the electrode layer 110 and the conductive layer 120 and increase durability.

Silicone materials are typically skin-friendly and can be attached to the skin without causing irritation, so that they are flexible enough to keep the skin and attached state as the skin of the living body moves.

The conductive layer 120 is formed not to cover the entire surface between the electrode layer 110 and the supporting layer 130 but to form a plurality of voids 121 having holes formed at regular intervals, The electrode layer 110 and the support layer 130 are in contact with each other so that the bonding state between the electrode layer 110 and the support layer 130 is maintained.

3, the connector connecting member 140 is connected to the conductive layer 120 and extends through the supporting layer 130 or is connected to the electrode layer 110 as shown in FIG. 4, (120) and the support layer (130).

A connector (not shown) is connected to an end of the connector connecting member 140 to supply an electrical signal to the electrode layer 110 or a measured signal from the electrode layer 110.

The electrode patch 100 according to the present invention includes the conductive layer 120 formed of conductive metal such as nickel or iron so that the conductivity is increased to decrease the resistance and the current conduction from the center portion to the peripheral portion of the electrode layer 110 It is uniformly performed without being half-cut. Therefore, in the electrode patch 100 of the present invention, the same resistance value can be obtained as compared with the conventional one in which the resistance value increases from the central portion to the peripheral portion of the electrode layer 110.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
