Description

  The present invention relates to a three-dimensional conductive fabric structure, and more particularly to a three-dimensional conductive fabric structure that achieves both elasticity and electrical conductivity.

As shown in FIG. 1, a sensing element 1 conventionally used for physiological detection includes a base layer 10 and a conductive layer 11 provided on the base layer 10, and when used, the conductive layer is attached to the skin of a human body. Thus, signals from the human body are detected.
Since the conductive layer 11 of such a sensing element 1 is inferior in elasticity and does not have a sufficient conductive effect with the human skin, it cannot detect signals from the human body and is not comfortable to put on.
Therefore, as shown in FIG. 2, an elastic layer 12 is added between the conductive layer 11 and the base layer 10 to increase the closeness between the conductive layer 11 and the human skin with the elastic layer 12 and to provide a moisturizing effect. Thus, it has improved so that the electroconductive effect of the conductive layer 11 may be improved by producing with a moisturizing material.
However, since the elastic layer 12 and the conductive layer 11 are two separate layers, if the elastic layer 12 tries to suck in external moisture, the water absorption effect is affected because the conductive layer 11 must be interposed. On the other hand, even when the elastic layer 12 releases moisture between the conductive layer 11 and the human skin, the release of the moisture is affected by the blocking of the conductive layer 11.
In addition, since the elastic layer 12 and the conductive layer 11 are two layers bonded (for example, bonded) by an external force, the elastic layer 12 is easily separated under the influence of high humidity over a long period of time, and the sensing element 1 is Will lose its effect.
