An electric conductive fiber structure includes an electric conductive resin containing electric conductive polymer(s), the electric conductive resin being filled in gaps between single fibers included in a fiber structure, the electric conductive fiber structure having 15% or more area ratio of the electric conductive resin present in an area of 15 to 30 &#x3bc;m from a surface when a cross section in a thickness direction of the fiber structure is observed.

Electric conductive fiber structure, electrode member, and method of producing electric conductive fiber structure

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.

Wearable electrode

A bioelectrode includes a fitting member () formed by an electrically insulating member fixed on a surface of a garment () that comes in contact with a living body (), an electrode part () formed by a conductive member fixed on a surface of the fitting member () that comes in contact with the living body (), a connector () fixed to the fitting member () and configured to connect a bioelectric signal measurement device, a wiring line () fixed to the fitting member () and configured to electrically connect the connector () and the electrode part (), and an electrically-insulating insulating member () configured to cover a portion within the surface of the wiring line () that comes in contact with the living body ().

Bioelectrode and garment

A biomedical electrode which is detachably attached to a garment and includes: an electrode coming into contact with a living body clothed in the garment to acquire a biological signal emitted by the living body; and a locked section which is conductive, is electrically connected to the electrode, is detachably locked to a locking section which is conductive and is provided in the garment, and is electrically connected to the locking section when locked to the locking section.

Biomedical electrode and wearable electrode

A soil resistant fiber structure, including a fiber and a soil resistant resin fixed to at least a part of a surface of the fiber, wherein the resin has, in at least a part inside the resin, one or more regions dyed with osmium oxide as observed with a transmission electron microscope, at least one of the regions is circular, the regions have a maximum diameter of 100 nm or more and 500 nm or less, and the soil resistant fiber structure has a mass concentration ratio of oxygen atoms to fluorine atoms (O/F) of 3 or more as obtained by measuring the surface of the fiber with an energy dispersive X-ray analyzer.
