FIG. 2 is a view illustrating signal connecting lines according to an embodiment of the present invention, and FIGS. 3A to 3C Is a view showing an electrode member according to an embodiment of the present invention.

Referring to FIGS. 1A to 3C, the bioelectrical signal sensing electrode 1 according to the present embodiment includes a sheet member 10, an electrode member 20, and a signal connection line 30. [

The sheet member 10 is made of a material having elasticity so that the electrode member 20 can be easily brought into close contact with the surface of the user's body while not giving the user a sense of foreign body. Since the sheet member 10 is made of a stretchable material, the electrode 1 for detecting a living body signal according to the present embodiment has the effect of minimizing the deterioration of the user's activity and maximizing the user's activity.

In addition, since the sheet member 10 can be in direct contact with the user's body surface, the sheet member 10 is free from problems such as skin damage and skin necrosis caused by long-term use even if the sheet member 10 is in direct contact with the user's body surface Lt; / RTI >

Further, the sheet member 10 is made of a nonconductive material. This is for the purpose of allowing a living body signal to be received only through the electrode member 20, as will be described later.

That is, the sheet member 10 is made of a material having biocompatibility, nonconductivity and stretchability. At this time, the sheet member 10 may be made of a material in which a poly (dimethyl siloxane) (PDMS) and a crosslinking agent are mixed.

Polydimethylsiloxane is a silicon-based polymer. Polydimethylsiloxane is a highly biocompatible material that does not cause problems such as skin damage and skin necrosis due to long-term use even if it is in direct contact with the user's body surface. In addition, polydimethylsiloxane is a nonconductive material as an insulating material. In addition, polydimethylsiloxane is a material that is not easily corroded or denatured, and is a semi-permanent adhesive material that maintains stickiness even if it is repeatedly attached to a user's body surface. In addition, polydimethylsiloxane is a material having elasticity, which minimizes the deterioration of the user's activity, maximizes the activity of the user, and easily absorbs external impact.

The sheet member 10 according to the embodiment of the present invention is made of such polydimethylsiloxane, has high biocompatibility, has semi-permanent adhesive property, and has an effect of maximizing user's activity.

The sheet member 10 is formed by applying a flowable mixture of a non-conductive material having biocompatibility with a cross-linking agent around the electrode member 20, and curing the applied mixture. For example, the mixture may be a mixture of polydimethylsiloxane and crosslinking agent in a ratio of 10: 1.

The electrode member (20) includes an electrode layer (21) and a metal member (22).

The electrode layer 21 is made of a material having elasticity so that it can be easily adhered to and adhered to the surface of the user's body and is not given to the user. Since the electrode layer 21 is made of a stretchable material, the electrode 1 for detecting a living body signal according to the present embodiment has the effect of minimizing the deterioration of the user's activity and maximizing the user's activity. The electrode layer 21 is made of a material having adhesiveness so as to be easily adhered to the surface of the user's body.

In addition, since the electrode layer 21 directly contacts the body surface of the user, the electrode layer 21 is made of a material that does not cause problems such as skin damage and skin necrosis due to long-term use even if it is in direct contact with the user's body surface.

The electrode layer 21 is made of a conductive material and detects a bio-signal, that is, an electrical bio-signal, from the body surface of the user who is in contact. For example, the biological signal detected by the electrode layer 21 includes an electrocardiogram signal, an EMG signal, a nerve signal, and an EEG signal. The material constituting the electrode layer 21 is not particularly limited as long as it is a substance having biocompatibility, conductivity, adhesiveness and stretchability as described above. For example, the material constituting the electrode layer 21 may be a conductive rubber which is a high molecular substance having conductivity.

The electrode layer 21 may have the shape of a disk having a diameter of a predetermined length. If the diameter of the electrode layer 21 is too small, the bioelectric signal can not be easily received from the user's body surface. Therefore, the diameter of the electrode layer 21 should be sufficiently large 10 mm or more).

The bio-signals detected by the electrode layer 21 include all electrical bio-signals that can be measured from the user's body surface. For example, the biological signal detected by the electrode layer 21 includes an electrocardiogram signal, an EMG signal, a nerve signal, and an EEG signal.

The electrode member 20 according to an embodiment of the present invention includes the metal member 22, thereby reducing such distortion generation problem.

On the other hand, if the electrode member including only the metal member is deformed by oxidation, if it comes into contact with the user's body surface, skin damage and skin necrosis due to long-term use may occur. The electrode member 20 according to an embodiment of the present invention includes the electrode layer 21 made of a non-metallic material and having a biocompatibility, thereby solving this problem.

Accordingly, the non-conductive material layer 102 including polydimethylsiloxane can effectively protect the yarns therein, and the electrode 1 for detecting the bio signal according to the present embodiment can be easily applied to wearable devices, do.

This indicates that the signal connection line 30 can easily transmit the bio-signal sensed by the electrode 1 for sensing the bio-signal to the external device.

The nonconductive material layer 102 is coated only on a part of the surface of the yarn 101. [ The uncoated surface of the yarn 101 is brought into contact with the electrode layer 21 or the metal member 22 so that the yarn 101 and the electrode layer 21 or the yarn 101 and the metal member 22 are electrically connected.
