(invention effect)

According to the present invention, it is possible to provide an electrical muscle stimulation device with improved convenience.

Since the electrical muscle stimulation device is worn on the user's body, it can detect various physiological information or action states related to the user's physical state. The electrical muscle stimulator detects a variety of physiological information or motion states, and various auxiliary methods related to the body can be thought of, or various methods of improving the convenience of the electrical muscle stimulator itself can be conceived.

The electrical muscle stimulation device in this embodiment provides electrical muscle stimulation, and includes: a sensor that detects information related to the user's body; and a control unit that controls voltage applied between electrodes and processes information detected by the sensor.

"Electric muscle stimulator" is an example of "sports equipment". In addition to the electrical muscle stimulator used to support the physical movement of creatures including humans, it can also be applied to various sports equipment used for sports or beauty. "Physiological information" includes not only information about the body such as vital signs (heart rate, blood pressure, respiration, body temperature, etc.), fat or muscle thickness, water content or blood flow, skin gas (ammonia, acetone, nitrogen dioxide, acetic acid, etc.), but also broadly includes information indicating the state of motion or activity of the body. The information indicating the motion state or the amount of activity of the body may include information used as a basis for indirect estimation in addition to values directly indicating the motion state or the amount of activity. For example, the value indicating the state of each muscle for estimating the user's body shape or posture, the value indicating the activity of muscles or organs for estimating the user's heart rate, the current value or electrical resistance value flowing in the body for estimating the user's activity, potential change, electrostatic capacity, acceleration of predetermined body parts, physiological magnetism, etc.

Hereinafter, the same or equivalent constituent elements, members, and steps shown in the drawings will be given the same reference numerals, and overlapping descriptions will be appropriately omitted. In addition, the dimensions of members in each drawing are appropriately enlarged and reduced for easy understanding. In addition, in each drawing, some members that are not important in the description of the embodiment are omitted and shown.

<Sports Equipment Control System> FIG. 1 is a schematic diagram showing an exercise equipment control system 100 according to an embodiment. The exercise equipment control system 100 is provided with: muscle electrical stimulation devices 10a to 10g as exercise equipment; an information terminal as the exercise equipment control device 12; and an information management server 14 for managing information. The electrical muscle stimulation device 10 includes a type worn on the user's abdominal muscles, flanks, arms, legs and other body parts (electric muscle stimulation devices 10a to 10f) and a type for the user to place on both feet (electric muscle stimulation device 10g). The electrical muscle stimulator 10 provides electrical stimulation by a weak current to the user's muscles. The electrical muscle stimulation devices 10a to 10g transmit and receive information by communicating with the exercise equipment control device 12 through short-range wireless communication such as Bluetooth (registered trademark), respectively. The exercise equipment control program executed in the exercise equipment control device 12 communicates with the electrical muscle stimulation devices 10a to 10g to control the individual settings and actions of the electrical muscle stimulation devices 10a to 10g. The sports equipment control device 12 is connected to the network 15 through wireless communication such as a wireless LAN (Local Area Network) or mobile phone communication, and transmits and receives information to and from the information management server 14 . The information management server 14 manages the update of the sports equipment control program executed by the sports equipment control device 12 , and receives and manages exercise setting information or result information from the sports equipment control device 12 . As a modified example, each electrical muscle stimulation device may be connected to the network 15 without passing through the exercise equipment control device 12 to communicate with the information management server 14 or the like.

The exercise equipment control device 12 is various information terminals operated by the user, such as mobile phone terminals such as smart phones, tablet terminals, personal computers, and the like. The exercise equipment control device 12 sets the corresponding relationship between the electrical muscle stimulation devices 10 a to 10 g and the body parts using the electrical muscle stimulation devices 10 , and controls the intensity setting or operation of each electrical muscle stimulation device 10 . The electrical muscle stimulation device 10 can be set or operated independently, and the user can directly operate the electrical muscle stimulation device 10 or operate it via the exercise equipment control device 12 . Since the exercise equipment control device 12 functions as a hub for the plurality of electrical muscle stimulation devices 10a to 10g, it is more efficient for the user to operate the exercise equipment control device 12 to collectively control the plurality of electrical muscle stimulation devices 10a to 10g than to set and operate the plurality of electrical muscle stimulation devices 10a to 10g individually.

FIG. 2 is a schematic diagram showing another aspect of the sports equipment control system 100 . In this aspect, the execution of the following exercise program is taken as a premise: multiple users simultaneously provide electrical stimulation through a plurality of muscle electrical stimulation devices, and at the same time move their bodies by themselves according to the instructions of the electrical stimulation pattern, thereby seeking muscle strengthening in a shorter time and more efficiently. The exercise equipment control system 100 includes: a plurality of fitness wear 102 loaded with a plurality of electrostimulation modules; an exercise equipment control device 12 ; a display control device 104 ; and a display device 106 . The exercise equipment control device 12, the display control device 104, and the display device 106 are regarded as a set, and one set or multiple sets are set up in a studio of a fitness gym, and each set prepares the upper and lower sets of fitness clothes 102 and the upper and lower sets of innerwear (not shown) respectively for a plurality of users up to seven. The electrical stimulation module is mounted on various parts of the fitness suit 102 so as to be able to provide electrical stimulation to various body parts such as the user's abdominal muscles, flanks, chest muscles, back muscles, arms, legs, buttocks, and the like. Each of the fitness clothes 102 for the plurality of users is equipped with a plurality of electrical stimulation modules. The exercise control program instructed to start executing through communication with the exercise equipment control device 12 controls the voltage setting and action in the plurality of electrical stimulation modules of each plurality of users. The sports equipment control device 12 transmits and receives information between the LAN and the display control device 104 via the network cable 108 . The display control device 104 is a computer that displays motion images on the display device 106 in accordance with the instructions of the motion control program executed by the sports equipment control device 12 .

The exercise equipment control device 12 is an information terminal operated by a gym trainer or a user. The exercise equipment control device 12 controls the intensity setting or operation of each user and each electrical stimulation module. Since the exerciser control device 12 functions as the operation center of the plurality of electrical stimulation modules for the plurality of users, it is more efficient to control the plurality of electrical stimulation modules by operating the exerciser control device 12 compared to the coach or the user individually setting and operating the plurality of electrical stimulation modules. In addition, it is possible to synchronize the operations of a plurality of users and control them together by the same program.

The sports equipment control device 12 displays the video as an exercise program explanation or an activity model on the display device 106 via the display control device 104 in a manner synchronized with the control of a plurality of electrical stimulation modules. However, the delay of wireless communication with each electrical stimulation module should also be considered, and the moving image can be displayed not at the timing (timing) completely synchronized with the control pulse of the electrical stimulation module, but at a timing delayed by a predetermined period of time. The display control device 104 may also have a built-in camera (camera) capable of photographing the user's movements, photograph the image of the user exercising in accordance with the exercise program, and display on the display device 106 an image that reproduces the movement of the skeleton based on the analysis of the image or the user's movement.

In this way, the exercise program in this embodiment is realized by interlocking the exercise control program that controls the voltage by the electrical stimulation module, and the exercise control program that makes the display device 106 display a synchronized image while transmitting a control signal such as a start signal to a plurality of electrical stimulation modules of a plurality of users through the exercise equipment control device 12 . Also, each user exercises his or her body using the image displayed on the display device 106 as a template, thereby executing the exercise program.

<Sports Equipment> FIG. 3 shows an example of the appearance of an electrical muscle stimulation device 10 as an example of sports equipment. (a) in FIG. 3 is a top view of the electrical muscle stimulation device 10a, (b) in FIG. 3 is an enlarged top view of the shell part, (c) in FIG. The electrical muscle stimulator 10 a includes a housing 20 , a cover 24 , a first base material 26 , a second base material 27 , a first electrode group 31 , a second electrode group 32 , a third electrode group 33 , and a fourth electrode group 34 . The main system of the muscle electrical stimulation device 10a mainly composed of the cover 24, the first base material 26 and the second base material 27 includes: the abdominal muscle part 21a, which is worn on the human abdominal muscle; the right abdomen 21b, which is worn on the right abdomen; and the left abdomen 21c, which is worn on the left abdomen.

The housing 20 is disposed at the center of the electrical muscle stimulation device 10a. As shown in (b) of FIG. 3 , the housing 20 is formed of resin and has a substantially elliptical shape in plan view. The casing 20 accommodates a power supply unit such as a lithium ion battery and a control unit (both will be described later in FIG. 4 ). A plus button 20a, a minus button 20b, an abdominal muscle specifying button 20c, and a flank specifying button 20d are provided on the plane side of the casing 20 as operation parts. The plus button 20a, the minus button 20b, the abdominal muscle specifying button 20c, and the flank specifying button 20d are formed in a cantilever state by hollowing out a part of the housing 20.

The first base material 26 and the second base material 27 are overlapped to form a base material. The cover 24 is formed of an elastomer such as silicone. The cover 24 covers the first base material 26 and the plane (surface) side of the housing. That is, the cover 24, the first base material 26, and the second base material 27 are stacked sequentially from the plane side. The cover 24 , the first base material 26 , the second base material 27 and the housing 20 are bonded by adhesive tape or adhesive. The part where the cover 24 covers the increase button 20a is protrudingly formed with a mark "+", and the part where the cover 24 covers the decrease button 20b is protruded with a mark "-". The part of the cover 24 covering the abdominal muscle designation button 20c is protrudingly formed with the character string "FRONT", and the part of the cover 24 covering the side abdomen designation button 20d is protruded with the character string "SIDE". The first base material 26 and the second base material 27 are sheet-shaped members, for example, formed of resin such as polyethylene terephthalate (polyethylene terephthalate).

The electrical muscle stimulation device 10 includes a set of positive and negative electrodes or multiple sets of positive and negative electrodes. In the case of the electrical muscle stimulation device 10a, the first electrode group 31 includes electrodes 31a to 31c, the second electrode group 32 includes electrodes 32a to 32c, the third electrode group 33 includes electrodes 33a, 33b, and the fourth electrode group 34 includes electrodes 34a, 34b. The electrodes are arranged on the back surface of the first base material 26 , that is, the surface in contact with the abdominal muscles or flanks, and are respectively exposed from the openings provided at the positions of the electrodes in the second base material 27 . Each electrode is made of conductive ink and printed on the back of the first substrate 26 . Electricity is passed between the electrode 31a and the electrode 32a, between the electrode 31b and the electrode 32b, between the electrode 31c and the electrode 32c, between the electrode 33a and the electrode 34a, and between the electrode 33b and the electrode 34b. In the second substrate 27, the openings 35a, 35b, 35c, 35d, 35e, 35f, 35g, 35h, 35i, 35j are respectively provided at positions corresponding to the electrodes 34a, 33a, 31a, 31b, 31c, 32a, 32b, 32c, 33b, 34b.

In addition, in the case of an electrode arrangement as shown in (c) in FIG. 3 , although the left and right rectus abdominis is energized in the transverse direction between the first electrode group 31 and the second electrode group 32, it may also be an electrode arrangement in which the left and right rectus abdominis are separately energized in the longitudinal direction (height direction). In this case, for example, only the first electrode group 31 independently applies electrical stimulation to the left rectus abdominis, and only the second electrode group 32 independently applies electrical stimulation to the right rectus abdominis. Thereby, electrical stimulation of different voltage values can be applied to the left and right rectus abdominis muscles.

A gel-like pad (not shown) is attached to the periphery of each opening and each electrode, and the electrical muscle stimulation device 10 is worn on each body part due to the adhesiveness of the pad. Elongated surface fastener bands (not shown) are attached to the end of the right abdomen 21b and the end of the left abdomen 21c, respectively. The electrical muscle stimulation device 10 is fixed by tightening the surface fastening belt with an appropriate length around the human body. The adhesive pad is electrically conductive, and electricity is supplied from each electrode to the body part of the user through the adhesive pad. The adhesive pad is exchanged when, for example, the adhesive force decreases due to the decrease in water content due to use, the electrical resistance increases, or when it is damaged or dirt becomes conspicuous.

Any one of the casing 20 , the first base material 26 , the second base material 27 , the first electrode group 31 , the second electrode group 32 , the third electrode group 33 , and the fourth electrode group 34 is provided with a sensor for detecting information related to the user's body. The sensors will be described later.

In addition, although the electrical muscle stimulation device 10a of the type worn on the abdominal muscles and flanks is illustrated in FIG. 3 , in the electrical muscle stimulation device 10 of the type worn on other body parts, a base material having a shape suitable for wearing on the body part is also formed, and the number of electrodes suitable for energizing the body part is provided. In addition, the electrical stimulation module mounted on the fitness suit 102 in FIG. 2 is similarly configured to include: a housing, a base material, and a pair of positive and negative electrodes or a plurality of pairs of positive and negative electrodes.

FIG. 4 is a block diagram showing the functional configuration of the electrical muscle stimulation device 10 . The electrical muscle stimulation device 10 includes a power supply unit 22 , a first base material 26 , and a control unit 28 . The control unit 28 includes a power control unit 50 , a skin detection unit 52 , an electrical stimulation control unit 54 , a setting unit 56 and a communication unit 58 . The power supply unit 22 is a secondary battery (secondary battery) such as a lithium ion battery, but may be an exchangeable primary battery (primary battery). The power supply unit 22 is electrically connected to the control unit 28 and supplies power.

The first substrate 26 includes a sensor 40 in addition to the first electrode group 31 , the second electrode group 32 , the third electrode group 33 and the fourth electrode group 34 . Although the example in which the sensor 40 is included in the first base material 26 has been described in this figure, the sensor 40 may be included in any one of the first electrode group 31, the second electrode group 32, the third electrode group 33, and the fourth electrode group 34 or individually. Alternatively, the sensor 40 is not included in the first substrate 26 or each electrode group, but the sensor 40 is included in the power supply unit 22 .

In terms of hardware, each block (block) of the control unit 28 can be realized by components or mechanical devices headed by a computer CPU (central processing unit), and in terms of software, it can be realized by computer programs, etc., and the functional blocks realized by such cooperation are described here. Therefore, those with ordinary knowledge in the technical field who have access to this specification should understand that these functional blocks can be realized in various forms by a combination of hardware and software. The same applies to each block in FIG. 5 and FIG. 6 .

The power supply control unit 50 controls the charging of the power supply unit 22 and transmits information indicating the charging state to the sports equipment control device 12 via the communication unit 58 .

The skin detection unit 52 detects whether the electrode contacts the skin based on the electrical resistance value received from the sensor 40 . The sensor 40 in this case is, for example, a physiological impedance (impedance) meter. The skin detection unit 52 obtains the electrical resistance value between the first electrode group 31 and the second electrode group 32 , and the electrical resistance value between the third electrode group 33 and the fourth electrode group 34 . The skin detection unit 52 detects that the electrode touches the skin when the detected electrical resistance value is less than the threshold value, and detects that the electrode does not touch the skin when the detected electrical resistance value exceeds the threshold value.

When the skin detection unit 52 detects that the electrodes are in contact with the skin, the electrical stimulation control unit 54 applies a set voltage between the electrodes with a predetermined operating time (for example, 23 minutes) and a predetermined cycle (for example, a cycle with a frequency of 20 Hz). That is, for example, electrical stimulation is given to the user's abdominal muscles and flanks. The setting part 56 receives the operation input of the up button 20a and the down button 20b arranged up and down, and increases or decreases the set voltage value applied by the electrical stimulation control part 54 . That is, the setting unit 56 increases the set voltage value every time the user presses the up button 20a, and decreases the set voltage value every time the user presses the down button 20b. The set voltage value can be set to any one of 20 levels of intensity, for example. The setting unit 56 further receives an operation input disposed on the left and right abdominal muscle specifying button 20c and the side abdomen specifying button 20d, and determines the set voltage value for operating the abdominal muscle portion 21a and the left and right flanks 21b, 21c. When the user wants to operate the set voltage value of the abdominal muscles, after pressing the abdominal muscle designating button 20c, the user adjusts the set voltage value with the plus button 20a and the minus button 20b. If you want to operate the set voltage value of the flank, after pressing the flank designation button 20d, adjust the set voltage value with the plus button 20a and the minus button 20b. The electrical stimulation control unit 54 increases or decreases the action time or period, the set voltage value, etc. based on the value detected by the sensor 40 . The control method according to the type of the sensor 40 will be described later.

The communication unit 58 receives the information of the set voltage from the sports equipment control device 12 through short-range wireless communication and transmits it to the setting unit 56 . When the communication unit 58 receives information on the set voltage value from the sports equipment control device 12, or receives information indicating an increase or decrease in the set voltage value, the setting unit 56 increases or decreases the set voltage value based on the received information. Whenever the set voltage value is increased or decreased, the electrical stimulation control unit 54 applies a voltage between the electrodes with a new set voltage value, so that the user can feel and confirm the new set voltage value, that is, let the user feel and confirm the new exercise intensity. The communication unit 58 increases or decreases the set voltage value when receiving an instruction to increase or decrease the exercise intensity from the exercise equipment control device 12 during exercise, that is, during voltage application. However, even if an instruction to increase or decrease the exercise intensity is received from other than the connected exercise equipment control device 12, it is ignored, and the instruction to increase or decrease the exercise intensity from other devices is not followed. This is to prevent the situation where the voltage value is increased or decreased arbitrarily by someone other than the user. The communication unit 58 transmits information indicating the voltage application status by the electrical stimulation control unit 54 , that is, information indicating the exercise execution status, to the exercise equipment control device 12 . The communication unit 58 transmits the information detected by the sensor 40 to the sports equipment control device 12 .

<Sports Equipment Control Device> FIG. 5 is a functional block diagram showing the functional configuration of the sports equipment control device 12 . The sports equipment control device 12 includes: a control unit 70 , a communication unit 71 and a display unit 72 . The control unit 70 includes: a communication processing unit 60 , a category determination unit 61 , a correspondence determination unit 62 , a setting processing unit 63 , an appliance control unit 64 , a display control unit 65 and an information management unit 66 .

The communication unit 71 transmits and receives information to and from the electrical muscle stimulation device 10 through short-range wireless communication, and transmits and receives information to and from the information management server 14 through a communication means such as a mobile phone communication network or a wireless LAN. The control unit 70 transmits and receives information with the electrical muscle stimulation device 10 or the information management server 14 through the communication unit 71 . The display unit 72 is a touch panel display device such as a liquid crystal panel or an organic EL (electroluminescence) panel, and displays information on a screen and accepts user's operation input.

The communication processing unit 60 transmits and receives information to and from the electrical muscle stimulation device 10 via the communication unit 71 . The content of the information received by the communication processing unit 60 from each of the plurality of types of sports equipment is different for each type of sports equipment. For example, the information received from each sports equipment includes identification information indicating the type of the sports equipment or the type of exercise. The information received from each sports equipment may also include individual identification information or a unique network address (MAC (medium access control; media access control) address) for user registration or individual management.

The category determination unit 61 specifies the category of sports using exercise equipment from a plurality of categories based on the received information. The type determination unit 61 stores in advance, for each type of exercise equipment, the types of exercises that can be performed by the type of exercise equipment. The category determination unit 61 stores exercise equipment names or exercise categories such as "Abs+Waist", "Abs", "Arm", "Leg", and "Body" in advance. The type determination unit 61 specifies the type of sports equipment based on the received information, thereby specifying the type of exercise. Here, if you specify sports equipment or sports category like "Abs+Waist" or "Abs", although there are cases where the body part using the equipment is uniquely determined like "Abs+Sides" or "Abs", for other sports equipment, the body part used is not necessarily unique. For example, "Arm" is not determined unless it is specified by the user which of the right arm and left arm is used, and which of the front and back of the arm is used. Similarly, "Leg" is not determined unless it is specified by the user which of the right leg and left leg is used, and which of the front and back of the leg is used. Since "Body" can use any of the flanks, arms, and legs, the body part to be used will not be determined unless the user specifies it. Therefore, the designation of the body part to be used is performed as follows by the kind of exercise equipment or the type of exercise.

The correspondence determining unit 62 designates correspondence with different sports equipment for each of the plurality of body parts based on the respective exercise categories designated for one or a plurality of sports equipment. The association determination unit 62 stores in advance one or more body parts that can be exercised by the type for each type of exercise. The correspondence determination unit 62 specifies the correspondence between any body part and the sports equipment based on the user's operation input to the display unit 72 when there are plural body parts that can be exercised by the type of exercise, that is, when the sports equipment that requires specifying the body parts is worn.

The setting processing unit 63 sets the operation content of the sports equipment based on the user's operation input to the display unit 72 . The setting processing unit 63 is capable of setting different motion details for a plurality of body parts. The setting processing unit 63 sets the intensity of the electrical stimulation by the muscle electrical stimulation device as the action content, that is, sets the voltage value of any one of 20 levels. The setting processing unit 63 adjusts the operation content of the electrical muscle stimulation device 10 based on the detection value of the sensor 40 obtained from the electrical muscle stimulation device 10 . The adjustment of the operation content based on the detection value from the sensor 40 will be described later. In addition, in this embodiment, although the following specifications are described: both the electrical stimulation control unit 54 and the setting processing unit 63 adjust the operation content or the setting voltage value of the electrical muscle stimulation device 10 based on the detection value from the sensor 40, but in a modified example, it is also possible to set the specification as follows: only one of the electrical stimulation control unit 54 and the setting processing unit 63 adjusts the operation content or setting voltage value of the electrical muscle stimulation device 10.

The equipment control unit 64 is based on the correspondence between the designated body parts and the sports equipment and the set motion content, and transmits information indicating the motion content to each sports equipment through the communication unit 71, thereby controlling the exercise performed by the sports equipment. For example, the device control unit 64 transmits an exercise start signal, a temporary stop signal, a completion signal, a voltage value signal, etc. to the electrical muscle stimulation device 10 to control the electrical muscle stimulation device 10 . On the other hand, in order to suppress battery consumption caused by communication in the electrical muscle stimulation device 10, it is preferable to keep the communication to a minimum in design. For example, the voltage value set in the electrical muscle stimulation device 10 is stored in the information management unit 66 , and information on the voltage value is not acquired from the electrical muscle stimulation device 10 . In addition, it is also possible to determine that the exercise program has been completed after a predetermined time elapses without transmitting and receiving an exercise completion signal.

The display control unit 65 controls the screen display of correspondence between body parts and exercise equipment, action content and exercise status. The display control unit 65 displays an image of a human body model, and displays on the screen an image dynamically showing the movement of muscles in motion in accordance with the control state of the exercise equipment. The display control unit 65 displays the visualized content on the screen based on the value detected by the sensor 40 .

The information management part 66 stores the registration information or attribute information of the user, the result information of the exercise, the detection value performed by the sensor 40, and the like. For user registration information or attribute information, for example, email address (mail address), password (password), nickname (nickname), date of birth, height, weight, gender and other information are stored. As the exercise result for each body part, the information management unit 66 uses the coefficient of each body part to determine the amount of exercise based on the action content set and performed for each body part, and records the cumulative amount of exercise. For example, the information management unit 66 may store coefficients corresponding to the average muscle area or electrode area of each body part in advance, and calculate the product of the voltage value, application time, and coefficients as one exercise amount. The amount of exercise may also be displayed in a unique unit such as "mp", for example. The information management unit 66 accumulates the calculated amount of exercise and stores it as an accumulated amount of exercise.

FIG. 6 is a functional block diagram showing the functional configuration of the information management server 14. As shown in FIG. The information management server 14 includes a control unit 80 and a communication unit 81 . The control unit 80 accumulates and manages the information received from each of the plurality of sports equipment control devices 12 . The communication unit 81 transmits and receives information between each of the plurality of sports equipment control devices 12 via a communication means such as a mobile phone communication network or a wireless LAN.

The control unit 80 includes a communication processing unit 85 and an information management unit 86 . The communication processing unit 85 transmits and receives information between a plurality of sports equipment control devices 12 via the communication unit 81 . The information management unit 86 accumulates and manages information received from a plurality of sports equipment control devices 12 . The information received from the sports equipment control device 12 is, for example, the setting information of the electrical muscle stimulation device 10 of each sports equipment control device 12 , the data of exercise results, and the detection value of the sensor 40 . The information management unit 86 stores the exercise control program, and sends a new version of the program to the exercise equipment control device 12 via the communication unit 81 when the exercise control program is updated.

In addition, although the sports equipment control system 100 in this embodiment has been described as including the information management server 14, it is also possible to realize the sports equipment control system 100 that does not include the information management server 14 as another form. In this case, the setting information or the exercise result information of each sports equipment control device 12 is mainly stored in the storage mechanism on the sports equipment control device 12 .

<Sensor> As described above, any one of the housing 20 , the first base material 26 , the second base material 27 , the first electrode group 31 , the second electrode group 32 , the third electrode group 33 , and the fourth electrode group 34 is provided with a sensor 40 for detecting information related to the user's body. By arranging some sensors in the electrical muscle stimulation device 10 , it is possible to obtain physiological information of the user, or to detect the operating state or action state performed by the user. The acquired or detected information is recorded as the user's use history or fed back to the control of the electrical muscle stimulation device 10 . Hereinafter, examples of sensors provided in the electrical muscle stimulation device 10 will be listed.

As sensors for detecting physiological information of users, there are Doppler sensors, ultrasonic sensors, physiological impedance measuring devices, near-infrared sensors, far-infrared sensors, skin gas sensors, thermometers, magnetic sensors, and the like. As sensors for detecting the user's motion state or activity level, there are Doppler sensors, myoelectric sensors, pressure sensors, acceleration sensors, cameras, and the like.

(1) Doppler sensor The Doppler sensor emits electric waves (microwaves) and compares the frequency of the reflected wave from the object with the frequency of the emitted wave to detect the movement of the object. The Doppler sensor must be installed at a remote location where it does not come into contact with the body of the user as the object. When the user's body is moving, the frequency of the reflected wave changes due to the Doppler effect, so that it can be determined whether the body is moving or still. For example, vital signs such as heart rate or breathing rate can be obtained by detecting body movements caused by heartbeat or breathing.

(2) Ultrasonic sensor The ultrasonic sensor is a sensor that emits ultrasonic waves and detects distance based on the return time of the reflected waves from the object. Based on the distance information detected by the ultrasonic sensor, the display control unit 65 of the exercise equipment control device 12 displays on the display unit 72 a cross-sectional image that visualizes the cross-section of the user's body. By visualizing the section of the user's body, the thickness of fat or muscle can be measured. Furthermore, based on the history of fat thickness or muscle thickness stored in the information management unit 66 or the information management unit 86, the effect of the muscle electrical stimulation device 10 can be measured. Unlike the Doppler sensor, the ultrasonic sensor must be installed at a position where it comes into contact with the body of the user as the object. For example, the rectus abdominis is installed at a position where the size and contraction of the muscle can be measured. Also, the ultrasonic sensor may be provided in the form of an ultrasonic probe that can be connected to the sports equipment control device 12 of FIG. 2 . In this way, the visualized cross-sectional image of fat or muscle can be displayed on the screen using the detection result of the ultrasonic sensor. Also, by measuring the thickness of fat or muscle and recording it as a history, changes in fat loss or muscle gain can be measured. Based on the thickness of fat or muscle, or in response to changes in fat loss or muscle growth, the setting processing unit 63 adjusts the action time, cycle, waveform, etc. as the training content performed by the muscle electrical stimulation device 10 . Also, the recommended frequency of training and the like may be determined. In addition, a specification may be adopted in which the ultrasonic sensor and the electrodes are provided on the same layer in the first base material 26 or the second base material 27 . In this case, the gel-like adhesive pad attached to the electrode can also be used as the gel-like member of the acoustic integration layer.

(3) Physiological impedance measuring device The physiological impedance measuring device measures the electrical resistance of the user's body by passing a weak current through the user's body. According to the relationship between the measured electrical resistance value and the stored physical information of the user such as height, weight, age, and gender, body composition values such as fat mass, muscle mass, and water content can be estimated. Although in order to flow a weak current to the body, the physiological impedance measuring device must be installed at a position in contact with the user's body, but it can also be set as an independent sensor and replaced with the following specifications: the first electrode group 31, the second electrode group 32, the third electrode group 33, and the fourth electrode group 34 are used instead, and the electrical resistance is measured by passing a weak current through these electrodes. The physiological impedance measuring device can adjust the electrical stimulation control unit 54 or the setting processing unit 63 to the set voltage value of the muscle electrical stimulation device 10 based on the measured electrical resistance value, or can analyze and give feedback on whether the electrode position is correct or not. Furthermore, the setting processing unit 63 adjusts the action time, cycle, waveform, etc. as the training content to be performed by the electrical muscle stimulation device 10 based on the result of the body composition analysis. Also, the recommended frequency of training and the like may be determined.

(4) Near-infrared sensor The near-infrared sensor detects, for example, the amount of moisture or blood flow in the user's body by the difference in the amount of reflection, absorption, and transmission when near-infrared rays, which are electromagnetic waves close to visible light, are irradiated on the user's body as an object. Thereby, the effect of training or vital signs such as the user's heart rate or pulse can be measured. For example, the setting processing unit 63 adjusts the operating time, cycle, waveform, etc. in response to changes in the amount of water or blood flow. For example, the presence or absence of edema may be determined, and the blood flow may be promoted by muscle movement (single contraction) caused by electrical stimulation of less than about 15 Hz based on the result of the determination.

(5) Far-infrared sensor The far-infrared sensor detects the far-infrared rays radiated from objects to detect small temperature differences. For example, the display control unit 65 of the exercise equipment control device 12 detects the change or body temperature distribution of the user's body temperature, and displays the change or body temperature distribution of the user's body temperature on the display unit 72 . In addition, it is also possible to install sensors at multiple places to detect body temperature from a plurality of body parts to which electrical stimulation is applied, and to estimate the difference in exercise efficacy or the balance of exercise for each body part. For example, the setting processing unit 63 adjusts the operation time, cycle, waveform, etc. according to these estimation results.

(6) Myoelectric potential sensor The myoelectric potential sensor measures the myoelectric potential generated by muscle contraction, and detects the potential change when the muscle moves. It is also possible to install multiple sensors so as to detect myoelectric potentials from a plurality of body parts to which electrical stimulation is applied, and to estimate differences in muscle motion or muscle fatigue for each body part, and balance of muscle motion. For example, the setting processing unit 63 adjusts the operation time, cycle, waveform, etc. according to these estimation results.

(7) Skin gas sensor The skin gas sensor is a sensor that detects gas released from the skin surface, and can detect skin gases such as ammonia (NH ₃ ), acetone, nitrogen dioxide (NO ₂ ), and acetic acid. For example, in a case where ammonia is detected by a skin gas sensor, user fatigue can be measured. In the case of detecting acetone by the skin gas sensor, it is possible to measure the fat burning amount of the user. In the case of detecting nitrogen dioxide by the skin gas sensor, the blood flow of the user can be measured. In the case of detecting acetic acid by the skin gas sensor, the user's fatigue can be measured. The setting processing unit 63 adjusts the operating time, cycle, waveform, etc. according to these measured values or their changes.

(8) Pressure sensor The pressure sensor is used to detect the change of electrostatic capacity caused by the deformation caused by pressure or the change of the electrical resistance value of the strain gauge (strain gauge). For example, body movements caused by heartbeat or breathing can be detected, so that vital signs such as heartbeat rate or breathing rate can be obtained. For another example, a pressure sensor can also be used to detect the pressure of the belt when the electrical muscle stimulation device 10 is wrapped around the body and to detect that the belt is too tight. The pressure of the user when sitting can also be detected by the pressure sensor. It is also possible to provide a pressure sensor on the bottom surface of the type (electric muscle stimulation device 10g) on which the user places both feet, so as to detect the shaking of the electric muscle stimulation device 10g described later. The setting processing unit 63 adjusts the operating time, cycle, waveform, etc. according to these measured values or their changes.

(9) Acceleration sensor The acceleration sensor detects the acceleration of the object, thereby detecting the speed of the user's muscle activity. In addition, the magnitude of muscle contraction may be measured based on the amount of exercise of the object. An acceleration sensor may be provided in a type (electric muscle stimulation device 10g) for the user to place both feet to detect shaking of the electric muscle stimulation device 10g described later. The setting processing unit 63 adjusts the operation time, cycle, waveform, etc. in response to these measured values or their changes, or the difference in the speed of movement of each body part.

(10) Thermometer The thermometer is used to detect the temperature of the object. For example, the body temperature of the user or the temperature of the environment is detected. Also, a hygrometer may be installed to further detect the humidity of the environment. The setting processing unit 63 adjusts the operating time, cycle, waveform, etc. in response to changes in the user's body temperature or the temperature of the environment.

(11) Image sensor An image sensor is a photographic element that obtains an image of a subject. The image sensor is used to detect the body shape or movement of the user, thereby locking the distortion or movement of the user's body. A camera built into the sports equipment control device 12 may also be used as an image sensor. The setting processing unit 63 adjusts the operation time, cycle, waveform, etc. in response to the twist or movement of the user's body.

(12) Physiological magnetic sensor The physiological magnetic sensor is used to detect the physiological magnetism of the user, so as to obtain vital signs such as heart rate. The setting processing unit 63 adjusts the operating time, cycle, waveform, etc. according to these measured values or their changes.

(13) Waist measurement device In the case of the electrical muscle stimulation device 10 of the type wrapped around the waist as shown in FIG. 3 , a waist measurement belt is provided to measure the waist. In addition, in the electrical muscle stimulator 10 of the type wound around body parts such as arms or legs other than the abdomen, a belt for measuring the circumference of the arms or legs may be provided to measure the circumference. Based on these measured values and other measured values, the user's body shape or body balance is estimated, and the setting processing unit 63 adjusts the operation time, cycle, waveform, etc. according to the estimated results.

For example, the following functions can be realized by using detection values obtained by various sensors. (1) Muscle balance The setting processing unit 63 adjusts the action time, cycle, and waveform in response to the following elements: the balance of muscle mass of each body part measured by sensors such as an ultrasonic sensor or a physiological impedance measuring device, or the balance of muscle movement or muscle fatigue of each body part measured by various sensors such as a myoelectric sensor or an infrared sensor. That is, the setting processing unit 63 adjusts so that it becomes training in the direction of alleviating the imbalance of the left and right muscles or the upper and lower muscles. When it is determined that the muscle mass of the left and right rectus abdominis or oblique muscles is unbalanced, the setting processing unit 63 may also set a larger voltage value for the rectus abdominis or oblique muscle on the side with less muscle mass as a set voltage value corresponding to the left-right difference. When the measured muscle mass of the left and right arms is unbalanced, the setting processing unit 63 may set a larger voltage value for the arm with less muscle mass as a set voltage value corresponding to the left-right difference. When the measured muscle mass of the left and right legs is unbalanced, the setting processing unit 63 may set a larger voltage value for the leg with less muscle mass as a set voltage value corresponding to the left-right difference. When the measured muscle mass of the upper body and the lower body, the muscle mass of the upper and lower sides, and the muscle mass of the front and back are unbalanced, the setting processing unit 63 may also set a larger voltage value for the muscle on the side with less muscle mass as a set voltage value corresponding to the difference. The setting processing unit 63 can also set the voltage value so as to be suitable for the user's electrical stimulation and exercise volume in relation to the following elements: the ratio of fat mass to muscle mass, fat mass to muscle mass, the stored physical information of the user such as height, weight, age, gender, and the user's desired body shape or exercise volume. As described above, it is possible to apply more appropriate electrical stimulation according to the body shape and muscle mass of different users.

(2) Electrical stimulation in response to heart rate In the case of obtaining vital signs such as the user's heart rate by Doppler sensors, near-infrared sensors, pressure sensors, and physiological magnetic sensors, the setting processing unit 63 adjusts the set voltage value of the muscle electrical stimulation device 10 in response to the heart rate. When the user's heartbeat is monitored by these sensors, the setting processing unit 63 can also apply electrical stimulation with a waveform matching the timing of the heartbeat, thereby promoting blood flow in a single contraction. When the heart rate exceeds a predetermined value and rises too much, the setting processing unit 63 lowers the set voltage value to suppress training. On the contrary, when the heart rate is lower than the predetermined value, the setting processing unit 63 increases the set voltage value to increase the intensity. As described above, the electrical muscle stimulation device 10 can be used more effectively.

(3) Reminder of Adhesive Pad Replacement A sensor detects whether the gel-like adhesive pad attached to the electrode of the electromuscular stimulation device 10 is worn out and should be replaced. For example, the composition (especially the water content) of the adhesive pad can also be detected by sensors such as a Doppler sensor, a physiological impedance meter, and a near-infrared sensor. In order to detect the moisture content of the adhesive pad, it is also possible to arrange the sensor in such a configuration that the sensor is sandwiched in a part of the adhesive pad. In addition, in addition to the specification that the physiological impedance measuring device measures the electrical resistance value of the adhesive pad while the electrode is energized between the user's body and the user's body, it may also be a specification that a dedicated impedance measuring device is installed near the electrodes, and the dedicated impedance measuring device is used to measure the electrical resistance value of the adhesive pad. When the setting processing unit 63 determines that the consumption of the adhesive pad is detected and it is in a state to be replaced, the display control unit 65 displays on the display unit 72 content urging the user to replace the adhesive pad. Also, information indicating that the adhesive pad should be exchanged may be sent to the information management server 14 via the communication unit 71, and the communication processing unit 85 of the information management server 14 that receives the information may automatically send a new purchase order for the adhesive pad to the user. As described above, it is possible to improve the user's convenience regarding the exchange of the adhesive pad, and it is possible to promote the appropriate utilization of the adhesive pad or the electrical muscle stimulation device 10 for the user.

(4) Waveform adjustment Since it is difficult to energize when the thickness of the fat or the amount of fat is large, in order to increase the frequency of electrical stimulation and increase the energization, the setting processing unit 63 adjusts the waveform according to the amount of fat. Specifically, according to the fat mass measured with an ultrasonic sensor or a physiological impedance measuring device, the frequency of the pulses constituting the electrified burst wave (burst wave) is adjusted to an appropriate depth and stimulation amount. For example, the frequency of the waveform is increased in case the fat mass exceeds a predetermined value. In particular, the interference pattern electrical muscle stimulation device 10 can adjust the waveform so as to reach the target site. As above, more effective electrical stimulation can be provided to the user.

(5) Output adjustment In the type in which the user places both feet (muscle electrical stimulation device 10g), since the ankle moves due to electrical stimulation when the electrical stimulation from the sole of the foot becomes stronger, the muscle electrical stimulation device 10g swings like a seesaw in conjunction with the ankle. Fig. 7 is a side view showing the use state of the muscle electrical stimulation device 10g. When using the electrical muscle stimulation device 10g, the user places both feet on the pair of foot parts 92L, 92R of the electrical muscle stimulation device 10g in a sitting posture. The sitting posture refers to a posture in which both feet FL and FR are hung down in a state of sitting on a stool such as a chair or the floor. Stimulation current for providing electrical stimulation flows through a pair of electrode parts to both legs. The stimulation current uses the user's left leg, right leg and the electrical muscle stimulation device 10g as a conduction path. When a stimulating current flows through both legs, electrical stimulation is given to the muscles of the front shin, calf, and sole of the foot, and the movements accompanied by the contraction and relaxation of these are promoted. That is, to promote the movement of the muscles under the knee or foot. When the muscles under the knees or feet are contracted by electrical stimulation, the feet FL and FR move in the direction Pa1 by bending the foot joints. On the other hand, when the contracted muscles relax due to the release of the electrical stimulation, the feet FL and FR move in the direction Pa2 so as to extend the foot joints. By repeatedly performing electrical stimulation on the muscles under the knees or the feet, the reciprocating rocking motion of the user's feet FL, FR in these directions Pa1, Pa2 is promoted. The main body 16 of the electrical muscle stimulation device 10g is configured to swing forward and backward as the front and rear ends move up and down when a part of the main body 16 of the electrical muscle stimulation device 10g is grounded. Thereby, when the shaking of the feet FL and FR is promoted by electrical stimulation in a state where the feet FL and FR are placed on the electrical muscle stimulation device 10g, the electrical muscle stimulation device 10g is shaken following the shaking. Accordingly, even when the feet FL and FR are shaken, the state where the feet FL and FR are in contact with the electrode parts of the electrical muscle stimulation device 10g can be maintained, and electrical stimulation can be continuously given by the electrical muscle stimulation device 10g. As a result, the rocking motion of the feet FL and FR is continuously promoted by the electrical muscle stimulation device 10g, and the effect of exercising muscles by electrical stimulation is obtained.

However, if the user is not used to using the electrical muscle stimulator 10g, there may be some users who hesitate to increase the voltage value and do not increase the voltage appropriately until the electrical muscle stimulator 10g is shaken. Therefore, a pressure sensor or an acceleration sensor is provided in the electrical muscle stimulation device 10g to detect shaking of the electrical muscle stimulation device 10g. In the case where the detected value indicating the vibration of the electrical muscle stimulation device 10g is lower than the predetermined value and it is determined that the vibration is insufficient, the user may be notified that the voltage value is insufficient or the user may be notified to increase the voltage to an appropriate value, or control to automatically increase the voltage to an appropriate voltage may be performed.

As mentioned above, this invention was demonstrated based on embodiment. It should be understood by those skilled in the art that this embodiment is an example, and various modifications can be made to the combination of each constituent element or each process (process), and these modifications also belong to the scope of the present invention. Modified examples are shown below.

In the above-mentioned embodiments, an example in which the electrical muscle stimulation device 10 is used as the exercise equipment to exercise the muscles by using the reflex motion caused by the electrical stimulation has been described. In the modified example, it can also be applied to the electrical muscle stimulation device 10 for hybrid training in which reflex motion by electrical stimulation is added to any exercise.

In the above-mentioned embodiment, the following specifications are described: the exercise equipment control device 12 is connected to the information management server 14, and transmits and manages the result of each user's exercise or the information registered by the user to the information management server 14 . In a modified example, the exercise equipment control system may be constituted by only a plurality of electrical muscle stimulation devices 10 and the exercise equipment control device 12 without using the information management server 14 . The electrical muscle stimulation device 10 may also have the display function, control function, and communication function of the exercise equipment control device 12, whereby the muscle electrical stimulation device 10 and the exercise equipment control device 12 may be integrally configured as one device. In this case, the user does not need to hold the exercise equipment control device 12 separately, and the communication part 58 of the electrical muscle stimulation device 10 communicates directly with the information management server 14 as shown in FIG. 4 . Moreover, since direct communication is possible between a plurality of electrical muscle stimulation devices 10, it is easy to synchronize the operations of the electrical muscle stimulation devices 10 with each other.

In the above-mentioned embodiments, the specifications defined as the exercise program, such as the exercise time for applying the voltage, have been described. In a modified example, the following specification may be used: not only the exercise time, but also the exercise program can be compiled in an optimized form such as the body part used, the exercise frequency, the schedule, and the set intensity according to the exercise purpose, the user's attributes, and the exercise history. In this case, notifications for urging the execution of the exercise may also be implemented in accordance with an appropriate schedule. In addition, it may be a specification in which the strength is gradually increased based on the history, or the strength is decreased according to the degree of fatigue, and the like, which is automatically adjusted.

As mentioned above, the first base material 26 and the second base material 27 are constituted by sheet-like members, and are formed into shapes suitable for wearing body parts, but the shapes of the base materials are not limited to sheet-like shapes. For example, the electrical stimulation module loaded on the gym clothes 102 uses a base material suitable for being loaded on the gym clothes 102 . The substrate may be formed in a rectangular shape such as a substantially rectangular shape on which each component of the power supply stimulation module is placed, or may be formed of a fiber material having shape stability and light weight. For example, the electrical muscle stimulation device 10g can use a material or a shape substrate suitable for placing feet.

In a modified example, the electrical muscle stimulator 10 is leased to the user at a cost, and the electrical muscle stimulator 10 may be operated only during the period when the price is paid. For example, the communication unit 58 or the communication unit 71 may inquire of the information management server 14 whether there is payment by the user, and the setting unit 56 performs control to validate the operation of the electrical muscle stimulation device 10 only when receiving information from the information management server 14 that there is payment and has a legitimate right to use.

In a modified example, the display control unit 65 of the sports equipment control device 12 may display the virtual avatar displayed as the user's avatar in a virtual reality space on the screen of the display unit 72 as shown in FIG. 8 . FIG. 8 shows an example of a screen on which an avatar is displayed. The avatar 110 whose muscle size can change according to the use history is displayed on the screen. The display mode of the virtual avatar 110 can be changed based on the use history of the user's electrical muscle stimulation device 10 . For example, changes in the growth of the muscles of the avatar 110 before and after the use of the electrical muscle stimulation device 10 can be displayed. For another example, the muscle growth can also be displayed on the screen by simulating according to the usage history of the electrical muscle stimulation device 10 such as the usage frequency, usage times, usage time, usage voltage value, etc. In this case, the user can use the electrical muscle stimulation device 10 with the sense of enjoying the game of developing the avatar 110 .

Arbitrary combinations of the above-described embodiments and modified examples are also effective as embodiments of the present invention. A new embodiment produced by combination combines the functions of the combined embodiments and modified examples. (industry availability)
