Abstract

A wearable electrode includes: a garment including an outer member and a backing member configured to cover at least a part of an inner surface of the outer member; and an electrode unit configured to come into contact with a living body clothed in the garment to acquire a biological signal emitted by the living body and attached to an opposite side of the backing member from the outer member. The outer member and the backing member are connected to each other in a part other than a part of the backing member, to which the electrode unit is attached.

First claim

The invention claimed is:

1. A wearable electrode comprising:
a garment including:
an outer member comprising an outer member neckline section and a pair of outer member armhole sections forming a Y-shape and adapted to be positioned on a user to avoid regions in which movements influenced thereto is relatively larger than other regions when a user clothed in the garment moves his or her neck or arms,
a backing member comprising a backing member neckline section and a pair of backing member armhole sections forming a Y-shape and adapted to be positioned on the user to avoid the regions in which movements influenced thereto is relatively larger than the other regions when the user clothed in the garment moves his or her neck or arms; and a back center surrounded by the backing member neckline section and the pair of backing member armhole sections and adapted to be positioned in front of the user; and
a wiring section disposed between the outer member and the backing member, the wiring section comprising:
an electrode unit attached to the back center on an opposite side of the inner surface of the outer member and adapted to acquire a biological signal from the user, wherein the outer member and the backing member are connected to each other by stitches and provided above a part of the backing member to which the electrode unit is attached;

a flexible connection wiring electrically connected to the electrode unit;
a locking section having a convex section and is electrically connected to the electrode unit;
a locked section having a concave section and is electrically connected to the flexible connection wiring, the locked section is detachably locked to the convex section and when the locking section and the locked section are locked to each other, the locking section and the locked section are electrically connected to each other;
a slit formed in the backing member and the convex section of the locking section being configured to be inserted into the slit;
a wire holding section having a loop, wherein the loop is attached above the slit to either the outer member or the backing member and is spatially separated from the electrode unit; and

wherein the flexible connection wiring is electrically connected to the locked section and the wiring section at a first end of the flexible connection wiring, the flexible connection wiring being drawn upward from the locked section, passing through the loop of the wire holding section, and then being routed downward from the loop of the wire holding section so that a second end of the flexible connection wiring is connected to a measuring device.

2. The wearable electrode according to claim 1 , wherein elongation percentages of the back center adapted to face a manubrium sterni and located between a pair of clavicles of the user is smaller than elongation percentages of parts of the backing member other than the back center when the user is clothed in the garment.

3. The wearable electrode according to claim 1 , wherein the back center is adapted to face a manubrium sterni located between a pair of clavicles of the user when the user is clothed in the garment.
