The myoelectric potential detection system of the present embodiment is not limited to the applications exemplified here, and can be used for various purposes in various fields.

FIG. 1 is an explanatory diagram showing a schematic configuration of a myoelectric potential detection system 1 according to the present embodiment.
FIG. 2 is a side view of the myoelectric potential detector 10A constituting the myoelectric potential detection system 1.
The myoelectric potential detection system 1 of the present embodiment includes two myoelectric potential detectors 10A and 10B and one smartphone 20. The myoelectric potential detectors 10A and 10B are connected to the smartphone 20 so that data communication is possible by short-range wireless communication such as Bluetooth (registered trademark). The communication between them may be realized by another wireless communication method or a wired communication method.

The two myoelectric potential detectors 10A and 10B have substantially the same configuration. In the present embodiment, the first myoelectric potential detector 10A is used as a master, the second myoelectric potential detector 10B is used as a slave, and the first myoelectric potential detector 10A, the second myoelectric potential detector 10B, and the smartphone 20 are simultaneously connected. Has been realized. In the myoelectric potential detection system of the present embodiment, two muscles are considered in consideration of the case of simultaneously detecting the myoelectric potentials of two detected portions, such as the case of simultaneously detecting the movement of the muscles of each calf of both feet. Although the potential detectors 10A and 10B are provided, the number of myoelectric potential detectors 10A and 10B may be one or three or more.

In the myoelectric potential detectors 10A and 10B of the present embodiment, the living body mounting portion mounted on the living body (human) is composed of three members, two electrode mounting portions 18a and 18b and a circuit mounting portion 18c. As shown in FIG. 2, the two electrode mounting portions 18a and 18b and the circuit mounting portion 18c are provided with electrode members 16a, 16b and 16c on the surface (mounting surface) on the side in contact with the human skin surface, respectively, as shown in FIG. Has been done. Of these electrode members 16a, 16b, 16c, the electrode members 16a and 16b provided on the first electrode mounting portion 18a and the second electrode mounting portion 18b are used as electrode members for detecting myoelectric potentials, respectively, and are used as circuit mounting portions. The electrode member 16c provided on the 18c is used as a ground electrode member for the ground (GND).

As the electrode members 16a, 16b, 16c, ordinary conductive members can be used, but magnets having conductivity may be used. In this case, the electrode members 16a, 16b, 16c can have a magnetic effect on a human body part such as a muscle under the skin surface of the person to be detected, and an effect such as blood circulation promotion can be expected. can. Further, since the electrode members 16a, 16b, 16c are magnets, for example, the myoelectric potential detectors 10A and 10B can be stored or carried in a state of being attracted by a magnetic force to a magnetic sheet or the like. It is possible to improve the property and portability.

Further, an adhesive sheet 17a made of an adhesive material such as an adhesive gel is attached to the mounting surfaces of the electrode mounting portions 18a and 18b and the circuit mounting portion 18c of the present embodiment with adhesive force so as to be adhered to the human skin surface with adhesive force. , 17b, 17c are provided. As a result, the electrode mounting portions 18a, 18b and the circuit mounting portion 18c can be attached to the human skin surface only by the adhesive strength of the adhesive sheets 17a, 17b, 17c. Therefore, it is not necessary to separately provide a mounting member such as a rubber band for mounting, and the myoelectric potential detectors 10A and 10B can be made smaller and lighter. Further, since the adhesive strength of the adhesive sheets 17a, 17b, 17c of the present embodiment is maintained even if they are peeled off once, they can be repeatedly attached and detached.

Further, the adhesive material constituting the adhesive sheets 17a, 17b, 17c of the present embodiment preferably has good conductivity in the frequency band where myoelectricity is generated. Since the adhesive sheets 17a, 17b, 17c have conductivity, not only the electrode members 16a, 16b, 16c but also the adhesive sheets 17a, 17b, 17c can be used as the electrode surface, and the myoelectric potential detection region can be obtained. It can be expanded to detect myoelectric potential more appropriately.

Further, in the circuit mounting unit 18c of the present embodiment, in addition to the ground electrode member 16c, a circuit component in which components of the control unit 11 and the short-range wireless communication device 15 are packaged, a power supply unit 12, a signal processing unit 13, and the like. A circuit board on which a sound output unit 14 and the like are mounted is provided. The ground electrode member 16c is provided on the mounting surface side in contact with the human skin surface, while the rest is provided on the surface opposite to the mounting surface as shown in FIG.

The two electrode mounting portions 18a and 18b in the present embodiment are connected to both sides of the circuit mounting portion 18c by flexible substrates 19, respectively. The electrode members 16a and 16b on the two electrode mounting portions 18a and 18b are electrically connected to the circuit board mounted on the circuit mounting portion 18c via the flexible substrate 19. As a result, the myoelectric potential detection signals (electrical signals) detected by the electrode members 16a and 16b on the two electrode mounting portions 18a and 18b are input to the circuit board of the circuit mounting portion 18c through the flexible substrate 19.

In the present embodiment, the two electrode mounting portions 18a and 18b are connected to the circuit mounting portion 18c by a flexible member such as the flexible substrate 19, so that the skin surface expands, contracts, and deforms due to the movement of muscles. However, as will be described below, the electrode mounting portions 18a and 18b and the circuit mounting portion 18c are unlikely to be displaced from the skin surface and are not easily detached.

The human skin surface to which the two electrode mounting portions 18a and 18b and the circuit mounting portion 18c constituting the living body mounting portion are mounted expands, contracts, and deforms according to the movement of muscles. On the other hand, the bio-mounted part on which the components constituting the myoelectric potential detectors 10A and 10B are mounted can usually follow the expansion, contraction, and deformation of the human skin surface due to manufacturing restrictions or cost restrictions. It is often composed of members such as solid substrates that do not have the flexibility of. Therefore, if the biological attachment portion is composed of a single member, the entire biological attachment portion cannot be deformed in accordance with the expansion, contraction, and deformation of the human skin surface, and the biological attachment portion may be displaced or detached from the skin surface. It's easy to do.

Therefore, in the present embodiment, the biological mounting portion is composed of three members, two electrode mounting portions 18a and 18b and a circuit mounting portion 18c, and these are connected to each other by a flexible member called a flexible substrate 19. doing. According to this configuration, even if the human skin surface expands, contracts, or deforms according to the movement of muscles, the flexible substrate 19 bends, returns, or bends in accordance with the expansion, contraction, or deformation. It can be twisted or twisted. Therefore, even if the electrode mounting portions 18a and 18b and the circuit mounting portion 18c are made of a member having no flexibility (for example, a solid substrate), the relative positions of the electrode mounting portions 18a and 18b and the circuit mounting portion 18c are flexible. It is possible to maintain the mounting state of the electrode mounting portions 18a and 18b and the circuit mounting portion 18c and the human skin surface.

In this embodiment, a flexible member is used as a connecting member between the electrode mounting portions 18a and 18b and the circuit mounting portion 18c, but the material itself expands and contracts or the shape (spring shape, etc.) is deformed. The same effect can be obtained by using an elastic member that expands and contracts.

Further, under the control of the control unit 21, the short-range wireless communication device 25 transmits, for example, the setting data of the notification conditions of the myoelectric potential detectors 10A and 10B to the myoelectric potential detectors 10A and 10B.

The external communication device 26 realizes data communication with various external devices including the information collection server 30 by wireless communication via a mobile communication line, a wireless LAN, or the like. Under the control of the control unit 21, the external communication device 26 transmits, for example, the myoelectric potential data transmitted from the myoelectric potential detectors 10A and 10B to the information collection server 30.

FIG. 4 is a flowchart showing the flow of notification processing in the present embodiment.
After the myoelectric potential detectors 10A and 10B are attached to the skin surface of the subject to be the detection point of the myoelectric potential, the power of the myoelectric potential detectors 10A and 10B is turned on (S1). As a result, the control unit 11 is activated, and the myoelectric potential according to the movement of the subject's muscle (muscle fiber activity) is changed to the first electrode mounting portion 18a and the second electrode mounting portion of the myoelectric potential detectors 10A and 10B. It is detected by the electrode members 16a and 16b provided on the 18b (S2).

The control unit 11 receives the myoelectric potential data detected by the electrode members 16a and 16b from the signal processing unit 13, and starts a process of transmitting the received myoelectric potential data from the short-range wireless communication device 15 to the smartphone 20. (S3).

Further, the control unit 11 determines whether or not a predetermined notification condition is satisfied based on the myoelectric potential data received from the signal processing unit 13 (S4). The notification conditions can be arbitrarily set according to the intended use and required functions.

For example, in rehabilitation, training, or the like, when the person to be detected performs an exercise that causes the muscles to move beyond a certain level, a notification condition that the detected myoelectric potential value exceeds a predetermined threshold value is set. In this case, for example, the control unit 11 executes notification control such as outputting a notification sound from the sound output unit 14 or vibrating the vibrator of the ground electrode member 16c during the period when the myoelectric potential exceeding the threshold value is detected. (S5).

At this time, if the notification sound continues to be output or the vibration continues during the period when the myoelectric potential exceeding the threshold value is detected, the person to be detected or surrounding humans may feel annoyed. In such a case, the notification condition is set so that the notification is performed when the detected myoelectric potential is equal to or lower than the predetermined threshold value, and the notification is not performed when the detected myoelectric potential exceeds the predetermined threshold value. You may. In this case, it is possible to eliminate the troublesomeness of notification when the muscle movement in which the detected myoelectric potential exceeds a predetermined threshold value is continuously performed.

The above processing operations (S2 to S5) are continued until the power of the myoelectric potential detectors 10A and 10B is turned off (S6).
