Description

  The present invention relates to a wearable electrode and a biological signal monitoring system used to acquire a biological signal (electrical signal from a living body).

  In recent years, “wearable devices” that operate while wearing devices such as computers, various sensors, communication apparatuses, and antennas have been attracting attention due to the integration of electronic components. In this wearable device, it is necessary to electrically connect each device in order to send detected information, receive a drive signal, and receive power supply.

  In this wearable device, each device is generally connected through a connector such as a PCB (Poly Chlorinated Biphenyl) connector (see, for example, Non-Patent Document 1).

  FIG. 12 shows an example of a conventional wearable device. In the figure, reference numeral 400 denotes clothing, and a sensor 401 that detects a biological signal is attached to a surface that contacts the wearer's M skin. A measuring device 402 that captures a biological signal detected by the sensor 401 is attached to a surface opposite to the surface of the clothing 400 that comes into contact with the skin of the wearer M.

  In this wearable device, the cable 401 a is derived from the sensor 401, the cable 402 a is derived from the measuring instrument 402, and both are connected by a connector 403. The connector 403 includes a columnar sensor-side housing 404 and a measuring instrument-side housing 405 made of an insulating material.

  One end of a cable 401a from the sensor 401 is connected to one bottom surface of the sensor side housing 404 by solder 404a. From the other bottom surface of the sensor-side housing 404, a rod-shaped convex terminal 404b protrudes in the axial direction. The convex terminal 404 b is electrically connected to the cable 401 a inside the sensor side housing 404.

  One end of a cable 402a from the measuring instrument 402 is connected to one bottom surface of the measuring instrument side housing 405 by solder 405a. On the other bottom surface of the measuring instrument side housing 405, a concave electrode 405b that is drilled in a columnar shape along the axial direction is provided. The concave electrode 405 b is electrically connected to the cable 402 a inside the measuring instrument side housing 405.

  In this wearable device, by inserting the convex terminal 404b of the sensor side housing 404 into the concave electrode 405b of the measuring device side housing 405, the sensor side housing 404 and the measuring device side housing 405 are mechanically connected, and the sensor 401 and the measuring instrument 402 are electrically connected.

  In this wearable device, the sensor 401 corresponds to the receiving electrode section referred to in the present invention, the measuring device 402 corresponds to the biological signal monitoring device, the sensor 401 including the clothing 400, the measuring device 402, the connector 403, the cable 401a, A configuration including 402a corresponds to the biological signal monitoring system, and a configuration including the sensor 401, the cable 401a, and the sensor-side housing 404 corresponds to the wearable electrode.

  However, in the conventional biological signal monitoring system, the feeling of wearing as clothing is poor due to the presence of connectors made of male and female housings.

  For example, in the configuration shown in FIG. 12, the cables 401a and 402b are separated from the clothing 400, and the connector 403 including the sensor-side housing 404 and the measuring instrument-side housing 405 moves together with the cables 401a and 402b. It will be a thing.

  In addition, the conventional biological signal monitoring system has a problem that the housing and the clothing come into contact with each other and rub against each other during washing, thereby reducing the durability of the clothing or the wearable electrode.

  For example, in the configuration shown in FIG. 12, when washing the garment 400, the sensor-side housing 404 and the measuring instrument-side housing 405 are separated, and the measuring instrument 402 is detached from the garment 400. Then, the clothes 400 are washed with the sensor 401 attached, that is, with the wearable electrode (sensor 401 + cable 401a + sensor-side housing 404) attached.

  In this case, the sensor-side housing 404 moves together with the cable 401a, contacts and rubs with the garment 400, and decreases the durability of the garment 400. In addition, a force is applied to the connection portion between the sensor 401 and the cable 401a, leading to deterioration of the wearable electrode.

  The present invention has been made in order to solve such problems, and the object of the present invention is to suppress deterioration of wearing feeling, deterioration of clothing durability, wearable electrode deterioration due to washing, and the like.

And a part of receiving electrode part, all the 1st connection parts, all the wiring parts, and a part of 2nd connection parts are coat | covered with the material which has waterproofness and insulation.

  Thereby, in the wearable electrode of this invention, a wiring part and a 2nd connection part do not move, and the deterioration of a wearing feeling is avoided. In addition, since the second connecting portion does not move when the clothes are washed, the durability of the clothes is not lowered. Moreover, since the 1st connection part and wiring part are coat | covered with the material which has waterproofness and insulation, durability at the time of washing of a wearable electrode is also ensured. In addition, since the wiring portion does not move when clothes are washed, no force is applied to the first connection portion, and the wearable electrode is not deteriorated.

  In the wearable electrode of the present invention, the second connecting portion is constituted by a magnet hook made of a conductive member, a conductive surface fastener, a conductive clip, a conductive fastener, a conductive metal snap button, or the like. Good.

  Further, in the wearable electrode of the present invention, the first connecting portion is formed by connecting the receiving electrode portion and the wiring portion by sewing with a conductive thread, sewing with a normal thread, crimping, caulking, adhesive, conductive adhesive, or the like. A structure to be joined is preferable.

  Further, in the wearable electrode of the present invention, a resin sheet is fixed to the surface opposite to the surface of the clothing that comes into contact with the wearer's skin, and the second connecting portion is bonded with the resin sheet interposed therebetween. It may be fixed to clothing by a method such as sewing, caulking, or crimping.

  Moreover, the biological signal monitoring system of the present invention includes the above-described wearable electrode and a biological signal monitoring device connected to the wearable electrode as an external device, and the biological signal monitoring device includes a second connecting portion of the wearable electrode. And a third connection portion that captures a biological signal detected by the receiving electrode portion of the wearable electrode.

As a third connection portion, a first set of third connection portions and a second set different in structure from the first set of second connection portions combined as a pair with the first set of second connection portions The second connection portion combined with the second connection portion as a pair may have a second set of third connection portions different in structure from the second set of second connection portions. In this case, the structure of the second connection portion of the first set is the same as the structure of the third connection portion of the second set, and the structure of the second connection portion of the second set is the third connection of the first set. If it is the same as the structure of the part, it becomes possible to prevent erroneous connection (erroneous mounting) when the biological signal monitoring device is connected to the wearable electrode.
