[First Embodiment]
First, with reference to FIG. 1 and FIG. 2, the biological signal measurement clothes according to the first embodiment of the present invention will be described. FIG. 1 is a configuration example of a biological signal measurement garment according to the first embodiment. FIG. 2 is a modification of the biological signal measurement garment according to the first embodiment.

  The garment 100 for measuring biosignals is provided on a plurality of connection terminals 11 provided on a bioelectrode 10 that detects a biosignal from a living body that is a measurement target, and a connector 20 that attaches a wearable device (not shown). A signal wiring 30 is provided for electrically connecting the plurality of connector receptacles 21 with independent individual wirings (wirings) 31 for each signal type of the connection terminals 11 and the connector receptacles 21.

  In the biological signal measuring garment 100 according to the present embodiment, the individual wirings 31 of the signal wiring 30 meander over the entire arrangement area 40 where the biological electrode 10 and the connector 20 are arranged, and are arranged so as to be parallel to each other. It is a thing. The meandering direction is not limited to the horizontal direction, and may be another direction such as a vertical direction or an oblique direction.

  The biological electrode 10 may be formed on the cloth of the biological signal measuring garment 100 using a known functional material such as “hiteo” described in Non-Patent Documents 1 and 2, for example. The signal wiring 30 may be sewn on the cloth of the biological signal measuring garment 100 using, for example, a known conductive thread that can be sewn. Further, the arrangement area 40 may be appropriately set according to the measurement position of the biological signal in the living body.

  In the present embodiment, as shown in FIGS. 1 and 2, two or three connection terminals 11 and connector receptacles 21 are used as one bioelectrode 10 and connector 20 as an example. The reason is as follows. For example, when measuring the myocardial action potential (electrocardiogram) associated with the heartbeat at one guiding position, when the wearable device detects an electrocardiogram with a differential input voltage, two plus and minus It suffices if there are electrodes, and the number of connection terminals 11 and connector receptacles 21 should be the same as those electrodes.

  On the other hand, in the case where an electrocardiogram is detected based on the difference from the reference potential by providing a ground (ground potential) instead of a differential input, it is sufficient to have a total of three detection electrodes in addition to plus and minus. 11 and the connector receptacles 21 need only be the same number. Even in the case of one lead, the wearable device may have four or more connector plugs, but the connector plugs from the fourth act as a mere fixture, etc. This is because it is assumed that connection with the individual wiring 31 is not required.

  In the configuration example of FIG. 1, the bioelectrode 10 is arranged in the arrangement area 40 so as to be in contact with the living body of the torso one by one on the left and right sides of the body midline. There are two individual wires 31 for connecting the biological electrode 10 and the connector 20, and the connector receptacles 21A and 21B of the connector 20 and the connection terminals of the biological electrodes 10 corresponding to the individual wires 31A and 31B, respectively. 11A and 11B are individually connected.

  Further, the individual wirings 31A and 31B do not cross each other, and are arranged in parallel while meandering over the entire arrangement area 40 with a specific interval A and interval B therebetween. The interval A between the different individual wirings 31A and 31B is the same as the interval between the connector plugs of the wearable device, for example, 4.6 cm. On the other hand, the interval B between the same individual wires 31A and 31B is an interval at which the connector plug of the wearable device is not attached, and is shorter or longer than 4.6 cm.

For example, the interval B is 5.6 cm. As for the connector receptacle 21, one set of connector receptacles 21 is arranged on the individual wiring 31 with the same distance as the distance between two connector plugs included in the wearable device.
Accordingly, the connector 20 can be disposed at a position 22X where both the individual wirings 31A and 31B exist, and is disposed at a position where either the individual wiring 31A or 31B does not exist, for example, a position 22Y where the individual wiring 31B does not exist. Also, miswiring can be avoided.

  In the modification of FIG. 2, three biological electrodes 10 are arranged, arranged so as to be in contact with the living body of the torso one by one on the left and right sides of the body midline, and in addition to one in the vicinity of the midline. Has been placed. There are three individual wirings 31 for connecting the biological electrode 10 and the connector 20, and the connector receptacles 21A, 21B, 21C of each connector 20 corresponding to the individual wirings 31A, 31B, 31C, and the biological electrodes, respectively. Ten connection terminals 11A, 11B, and 11C are individually connected.

The individual wirings 31A, 31B, and 31C do not cross each other, and are arranged in parallel while meandering over the entire arrangement area 40 with a specific interval A, interval B, and interval C therebetween. The interval A and the interval B are the same as those in FIG. 1, and the interval C between the individual wires 31B and 31C is designed to match the triangular shape of the connector plug of the wearable device. For example, the interval C is 4.3 cm.
As a result, the connector 20 can be disposed at the positions 22X and 22Z where all of the individual wirings 31A, 31B, and 31C exist, and a position where any of the individual wirings 31A, 31B, and 31C does not exist, for example, the individual wirings 31B and 31C. Even if it is arranged at the position 22Y that does not exist, erroneous wiring is avoided.

It is formed to do.
As a result, even when the connector 20 is placed on the placement area 40 other than the left shoulder, each connector receptacle 21 can be connected to the individual wiring 31 that passes through the placement location.

  Therefore, since the arrangement of the signal wiring 30 can be unified in the biological signal measuring garment 100, the wearable device can be attached to various positions by changing only the arrangement position of the connector 20. For this reason, it is possible to easily cope with a wide variety of uses required for the garment 100 for measuring biosignals, and to greatly reduce the cost for preparing various types of garments 100 for measuring biosignals. It becomes possible.

Moreover, since the position of the signal wiring 30 in the biological signal measuring garment 100 can be fixed regardless of the arrangement position of the connector 20, the specifications and the manufacturing process of the signal wiring 30 can be unified. For this reason, it is possible to significantly reduce the manufacturing cost of the biological signal measuring garment 100.
Therefore, according to the present invention, it is possible to provide a garment for measuring a biosignal capable of attaching a wearable device to a plurality of different positions without increasing manufacturing costs, and a wide range of sports, health care, medical care, and the like.
