Bioelectrode and garment
A bioelectrode includes a fitting member ( 1106 ) formed by an electrically insulating member fixed on a surface of a garment ( 1100 ) that comes in contact with a living body ( 1000 ), an electrode part ( 1101 a ) formed by a conductive member fixed on a surface of the fitting member ( 1106 ) that comes in contact with the living body ( 1000 ), a connector ( 1102 a ) fixed to the fitting member ( 1106 ) and configured to connect a bioelectric signal measurement device, a wiring line ( 1103 a ) fixed to the fitting member ( 1106 ) and configured to electrically connect the connector ( 1102 a ) and the electrode part ( 1101 a ), and an electrically-insulating insulating member ( 1105 ) configured to cover a portion within the surface of the wiring line ( 1103 a ) that comes in contact with the living body ( 1000 ).
1. A bioelectrode comprising:
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, at least a part of the wiring line arranged on and along the surface of the fitting member that comes in contact with the living body; and
an electrically-insulating first insulating member configured to cover a portion of a surface of the wiring line that comes in contact with the living body.
2. The bioelectrode according to claim 1 , wherein the connector is fixed on the surface of the fitting member that comes in contact with the living body.
3. The bioelectrode according to claim 1 , further comprising an electrically insulating second insulating member configured to insulate the connector and the garment from each other,
wherein the connector includes a conductive part configured to connect the bioelectric signal measurement device, the conductive part being exposed to a surface of the garment opposite to the surface that comes in contact with the living body,
the wiring line couples with the connector on a side of the connector that comes in contact with the living body, and
the first insulating member covers respective portions of the surfaces of both the connector and the wiring line that come in contact with the living body.
4. The bioelectrode according to claim 3 , further comprising a reinforcing member that has a Young's modulus larger than that of a material of the garment,
wherein the connector is fixed to the garment by being penetrated through the garment, and
the reinforcing member is fixed to the garment in a state in which the connector penetrates through a hole formed in the reinforcing member along a thickness direction of the reinforcing member and a hole formed in the garment along a thickness direction of the garment.
5. The bioelectrode according to claim 3 , wherein the second insulating member is formed on a surface of a portion of the connector that comes in contact with the garment.
6. The bioelectrode according to claim 1 , further comprising an electrically insulating second insulating member configured to insulate the connector and the garment from each other, and insulate the wiring line and the garment from each other,
wherein the connector includes a conductive part configured to connect the bioelectric signal measurement device, the conductive part being exposed on a surface of the garment opposite to the surface that comes in contact with the living body,
the wiring line is arranged through a through hole formed in the garment, and couples with the connector on a side of the garment opposite to the side that comes in contact with the living body, and
the first insulating member covers respective portions of the surfaces of both the connector and the wiring line that come in contact with the living body.
7. The bioelectrode according to claim 6 , further comprising a reinforcing member that has a Young's modulus larger than that of a material of the garment,
wherein the connector is fixed to the garment by being penetrated through an inside and an outside of the garment, and
the reinforcing member is fixed to the garment in a state in which the connector penetrates through a hole formed in the reinforcing member along a thickness direction of the reinforcing member and a hole formed in the garment along a thickness direction of the garment.
8. The bioelectrode according to claim 6 , wherein the second insulating member is formed on a surface of a portion of the connector that comes in contact with the garment.
9. The bioelectrode according to claim 6 , wherein the second insulating member is arranged on the surface of the garment opposite to the one that comes contact with the living body, and
the wiring line includes another part arranged on and along the surface of the second insulating member opposite to the one that comes contact with the garment.
10. The bioelectrode according to claim 1 , further comprising a fixing aid cloth formed between the fitting member and the garment.
11. The bioelectrode according to claim 10 , further comprising an adhesive fixing the fixing aid cloth to the garment, wherein the fixing aid cloth is one of a woven fabric, a knitted fabric, and a nonwoven fabric containing at least one of polyester, nylon, acryl, and urethane, and an adhesive force between the fixing aid cloth and the adhesive is larger than that between the garment and the adhesive.
