発明の名称 (英語) STRETCHABLE RAISED FIBER ELECTRODE AND MANUFACTURING METHOD THEREFOR UPDATE コモンズ 新技術説明会
発明の概要(英語) Provided is a stretchable raised fiber electrode that is stretchable and can be used as a bioelectrode for being pressed against a body to collect a biological signal. Also provided is a manufacturing method for said stretchable raised fiber electrode. In the raised fiber electrode, the fibers are made to stand upright on a surface of a stretchable sheet. The raised fiber electrode includes a resin layer (2) that is strechably provided along the surface of the sheet (1), and a plurality of conductive fibers (3) that each have an insertion section that is inserted into the resin layer (2) at one end thereof. Neighboring conductive fibers (3) are in electrical contact with one another in sections that are not inserted into the resin layer (2), and the conductive fibers (3) are provided to the resin layer (2) at such a density that the conductivity of the electrode region of the sheet member (1) to which the conductive fibers (3) are provided is isotropic in-plane. This raised fiber electrode can be provided according to an electrostatic spray method.
従来技術、競合技術の概要(英語) BACKGROUND ART
Is pressed against the uneven surface of the object to the object and the current can flow between the flexible flexible electrodes have been known.As one of the flexible electrode 1, pressed against the body to collect the biological signal of the biometric measurement electrode is an electrode.For example, the body of the human body and the conductive sheet between the biological electrode is pressed against the conductive gel is applied, a living body such as the electrocardiogram signals are being collected.The body portion and the conductive gel is electrically between the biological electrode is filled with a weak current can be measured securely used.
However, the sensitivity of the skin in such a case, the conductive gel directly, can be in contact with the skin may not be favored, in addition, applications such as wearable electrode for a long time even in the case of using the conductive gel is a demand of the user does not want.Therefore, the conductive gel without using the following uneven surface of the object in a very weak current so as to collect a living body, the resilient expansion and contraction of the substrate using the electrode layer having transparency, or, the electrode base material on the surface of the conductive fibers are flocked, and the like to raise has been proposed.
For example, in Patent Document 1, the thickness and elasticity of the sponge or the like around a holding portion having a conductive fiber cloth made of an electrically conductive and flexible such as a detection unit is applied to the biological electrode is disclosed.Disposed on the inside of the garment biometric electrodes and deformed to the living body is obtained in improving the adhesion, and does not have elasticity.On the other hand, in Patent Document 2, a stretchable cloth member with respect to the strip-shaped electrodes made of conductive fibers continuously processing a non-woven fabric, weaving, or, by braiding is integrated with the biological electrode is disclosed.Biometric electrodes, the base material of the cloth member is a contract, a non-retractable portion of the strip-shaped electrodes.Therefore, the strip-shaped electrodes, for example, as disclosed in Patent Document 3, conductive stretch film may be used can be taken into consideration.
In addition, in Patent Document 4, the electrode sheet is not used to collect the brain wave as biological electrodes, a plurality of conductive fibers extending from the base in a state where the contact to raise the raising electrode are disclosed.Such an electrode has, the base is neither expanded nor contracted, and the contactors can be flexibly moved substantially to the expansion and contraction of the electrode.
