However, this invention discloses a configuration in which a control module operates according to the user's input module manipulation to adjust the intensity and frequency of the electrical stimulation, but does not disclose a configuration in which stimulation is applied according to the user's actual muscle fatigue and amount of exercise. Therefore, there is a limitation in that it cannot control the appropriate stimulation necessary for the user's fatigue recovery.

[0033] In describing the present invention, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the present invention, the detailed description is omitted.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. In order to facilitate an overall understanding in describing the present invention, the same reference numbers will be used for the same means regardless of the drawing numbers.

[0035]

[0036] FIG. 1 is an exemplary drawing of a service using a smart muscle band according to one embodiment of the present invention, and FIG. 2 is an exemplary drawing of a user wearing a smart muscle band according to one embodiment of the present invention.

[0037] As illustrated in FIG. 1, a user can exercise while wearing a plurality of smart muscle bands (100) according to the present invention on their arms and legs. At this time, the smart muscle band (100) obtains electromyography signals from electromyography measuring electrodes (111) that are in contact with the skin of a specific body part of the user, and obtains strain data of a strain sensor (121) that repeats elongation and contraction due to the changing muscle thickness of the user. The smart muscle band (100) predicts muscle activity and muscle fatigue based on the electromyography signals, determines a stimulation voltage according to the predicted muscle fatigue, and then applies electrical stimulation according to the determined stimulation voltage to the user's muscles using muscle stimulation electrodes (112), thereby relaxing the user's muscles that are stiff due to exercise.

[0038] A smart muscle band (100) may be equipped with a controller (113) and a communication device (114). When a user wears multiple smart muscle bands (100) and exercises, one of the controllers (113) of the multiple smart muscle bands (100) may function as a master controller, and the rest may function as slave controllers. At this time, the controller (113) functioning as a master controller may perform synchronization and power control of other smart muscle bands (100) via the communication device (114). For example, the controller (113) functioning as a master controller may transmit a control signal to a slave controller via the communication device (114) when the power is turned on, thereby synchronizing the slave controller, i.e., other smart muscle bands (100). In addition, when the power of the smart muscle band (100) including the master controller is turned off, the controller (113) acting as the master controller can transmit a power control signal to the slave controller through the communication device (114) so ​​that the power of other smart muscle bands (100) including the slave controllers is turned off. For example, when a user wears a smart muscle band (100) on each of the left arm, right arm, left leg, and right leg and exercises, the four smart muscle bands (100) are synchronized and the power is controlled simultaneously.

[0039] For example, when a user wears a wearable suit made of conductive fibers and exercises, a plurality of smart muscle bands (100) can be connected to each other by wires through contact points with the wearable suit. As another example, the communication device (114) can be equipped with a Bluetooth module, and in this case, even if the user does not wear the wearable suit, a plurality of smart muscle bands (100) can establish a wireless connection with each other through Bluetooth communication to transmit and receive control signals or data.

[0040]

[0041] FIG. 3 is a block diagram showing the configuration of a smart muscle band according to one embodiment of the present invention.

[0042] A smart muscle band (100) is a device that is attached to a specific body part of a user, collects electromyography signals generated from muscles of said body part and sensing data of a strain sensor (121) that changes according to changes in the thickness of the user's muscles, calculates and monitors muscle activity, muscle fatigue, and exercise amount (e.g., number of exercise sessions) based on the collected electromyography signals and sensing data, and applies appropriate electrical stimulation to the user's muscles according to the muscle fatigue to relieve the user's muscle fatigue.

[0043] Referring to FIG. 3, a smart muscle band (100) according to one embodiment of the present invention includes a conductive pad (110) and a band portion (120).

[0044] The conductive pad (110) includes an electrode for electromyography measurement (111), an electrode for muscle stimulation (112), a controller (113), a communication device (114), and a fixing part (115), and the band part (120) includes a strain sensor (121), a basic circumference measurement circuit (122), and an elastic part (123).

[0045] The conductive pad (110) and the band portion (120) are physically connected and electrically coupled through the fixing portion (115). The smart muscle band (100) illustrated in FIG. 3 is according to one embodiment, and the components of the smart muscle band (100) according to the present invention are not limited to the embodiment illustrated in FIG. 3, and may be added, changed, or deleted as needed.

[0046] The conductive pad (110) obtains electromyography signals generated from muscles of a specific body part of the user through an electromyography measuring electrode (111), calculates muscle fatigue of the muscle based on the electromyography signals, and determines a stimulation voltage to be applied to the muscle based on the muscle fatigue.

[0047] The band part (120) may have a belt shape. The band part (120) is physically and electrically connected to the conductive pad (110), and is mounted on the body part in a form where one end and the other end of the band shape are connected while wrapping around the circumference of the body part, thereby fixing the conductive pad (110) to the body part. At this time, the electromyography measuring electrode (111) and the muscle stimulation electrode (112) included in the conductive pad (110) are brought into close contact with the body part.

[0048] In addition, the band part (120) transmits strain data of the built-in strain sensor (121) to the conductive pad (110), and the conductive pad (110) can calculate the number of times the muscle is moved based on the strain data of the strain sensor (121).

[0049] As described above, the conductive pad (110) includes an electrode for electromyography measurement (111), an electrode for muscle stimulation (112), a controller (113), a communication device (114), and a fixing member (115).

[0050] The electromyography measuring electrode (111) acquires electromyography signals generated from the muscles. A plurality of electromyography measuring electrodes (111) are arranged on a conductive pad (110). For example, three electrodes, such as a ground electrode, a reference electrode, and a signal electrode, may be arranged on one conductive pad (110), and the controller (113) can analyze the electromyography signals generated from the three electrodes to predict the muscle activity and muscle fatigue of the corresponding muscle of the target body part.

[0051] The controller (113) includes an amplifier that can amplify an analog signal (e.g., an electromyography signal, strain data of a strain sensor (121)) and a processor that performs computational processing. The controller (113) analyzes the electromyography signal using FFT (Fast Fourier Transform) and spectrum analysis to calculate muscle activity and muscle fatigue of the muscle, and determines a stimulation voltage to be applied to the muscle based on the muscle fatigue. In addition, the controller (113) can calculate the number of times the muscle is exercised based on the strain data of the strain sensor (121).

[0052] The controller (113) can determine the stimulation voltage according to a preset stimulation voltage function. For example, the stimulation voltage function can be a wave function, and the wave function can be determined from among a sine wave, a rectangular wave, a triangular wave, and a sawtooth wave. The controller (113) can increase or decrease the amplitude of the wave function according to the degree of muscle fatigue, and an exponential function can be applied to the amplitude. For example, the controller (113) can set the amplitude of the wave function to increase exponentially as the degree of muscle fatigue increases. That is, the amplitude can be calculated as an exponential function of the degree of muscle fatigue. An upper limit and a lower limit can be set for the amplitude.

[0053] The controller (113) can determine the number of times, intervals, and application times of stimulation voltages according to muscle fatigue. For example, the controller (113) can shorten the period of the stimulation voltage function when muscle fatigue increases. As another example, the controller (113) can use a logarithmic function to determine the number of times the stimulation voltages are applied during a predetermined period. That is, the controller (113) can use a logarithmic function to initially set the number of times the stimulation voltages are applied to a small number of times and then gradually increase the number of times the voltages are applied.

[0054] Meanwhile, as an example different from the above-described embodiment, the controller (113) can calculate muscle activity of a muscle of a target body part based on strain data of a strain sensor (121) and supplement (correct) the accuracy of the calculated muscle activity based on an electromyography signal.

[0055] As another example, the controller (113) can calculate muscle fatigue based on the pattern shown in the EMG signals generated from three electrodes and the strain data of the strain sensor (121). For example, the controller (113) can calculate muscle fatigue using the EMG signals generated from three electrodes, and then correct the calculated muscle fatigue using the wavelength of the strain data. This is to reflect the fact that the wavelength of the strain data may become longer as the user becomes more tired.

[0056] The muscle stimulation electrode (112) applies a stimulation voltage (electrical stimulation) determined by the controller (113) to the muscle.

[0057] The communication device (114) transmits and receives control signals or data through wired / wireless communication with the communication device (114') of another smart muscle band (100') or an external device (e.g., a mobile device such as a smartphone or laptop).

[0058] For example, the controller (113) can transmit the collected muscle activity, muscle fatigue, and exercise count data to an external device via a communication device (114) so ​​that the user can check it.

[0059] Meanwhile, the communication device (114) may include a Bluetooth module. The controller (113) may synchronize another smart muscle band (100') with the smart muscle band (100) via the communication device (114), and may control the power of the other smart muscle band (100') to be turned off when the power of the smart muscle band (100) is turned off.

[0060] Specifically, the controller (113) transmits a predetermined control signal to a controller of another smart muscle band (100') (hereinafter referred to as a 'second controller') through a communication device (114) so ​​that the second controller is synchronized with the controller (113). In addition, the controller (113) can transmit muscle activity, muscle fatigue, and exercise number data to an external device (e.g., a mobile device) through the communication device (114).

[0061] The fixing part (115) physically couples and electrically connects the conductive pad (110) and the band part (120). For example, the fixing part (115) may physically couple the conductive pad (110) and the band part (120) via a magnet, and electrically connect the conductive pad (110) and the band part (120) via an electrical contact. Accordingly, the band part (120) may transmit strain data of the strain sensor (121) and a current signal (resistance value) of the basic circumference measurement circuit (122) to the controller (113). For example, the fixing part (115) may be a pogo pin.

[0062] As described above, the band portion (120) includes a strain sensor (121), a basic circumference measuring circuit (122), and an elastic portion (123).

[0063] The basic circumference measuring circuit (122) has a characteristic in which the resistance value varies according to the circumference of the body part at the time the band part (120) is worn on the user's specific body part. Specifically, the band part (120) has a band shape and is worn on the body part in a manner in which one end and the other end of the band shape are joined while wrapping around the circumference of the body part. At this time, the joining positions of the one end and the other end vary according to the circumference of the body part, and the basic circumference measuring circuit (122) has a structure in which the resistance value is determined according to the joining position, so that the resistance value is ultimately determined according to the circumference of the body part. Accordingly, the controller (113) can estimate the circumference of the body part based on the resistance value of the basic circumference measuring circuit (122). The controller (113) calculates the basic length of the body part based on the resistance value of the basic circumference measuring circuit (122) at the time the band part (120) is worn on the body part.

[0064] The strain sensor (121) obtains strain data due to changes in the length of the circumference. The strain data is data measured based on changes in the resistance value of a variable resistor built into the strain sensor (121).

[0065] The controller (113) calculates the basic length of the circumference of the body part based on the resistance value of the basic circumference measurement circuit (122), and calculates the final length of the circumference by correcting the basic length using the strain data. For example, the controller (113) can measure the length of the circumference of the target body part (e.g., arm, leg) in mm based on the strain data generated by the strain sensor (121). Since the strain data varies depending on the change in muscle thickness of the body part, the final length may continuously change while the user is exercising.

[0066] In addition, the controller (113) can calculate muscle activity based on strain data generated by the strain sensor (121), and can correct muscle activity based on electromyography signals acquired through the electromyography measuring electrodes (111). The controller (113) can calculate the user's exercise amount (e.g., number of exercise sessions) based on muscle activity, and can measure changes in the user's muscle mass by monitoring the circumference of the target body part over a long period of time, and can determine whether or not the user has sarcopenia.

[0067] The elastic portion (123) is a portion of elastic material that occupies a specific area of ​​the band portion (120), and can be stretched according to the length of the circumference of the body part of the user to which the band portion (120) is attached. Accordingly, the smart muscle band (100) can be worn in close contact with the body part.

[0068] In addition, the elastic portion (123) may further include a portion made of a shape memory alloy in addition to the elastic material. For example, the band portion (120) may automatically fit to a user's body part through the contraction action of the shape memory alloy wire. Since the shape memory alloy consumes a lot of current, an electrostatic clutch may be additionally provided in the elastic portion (123) to reduce the current consumption due to the shape memory alloy and further improve the fit. The controller (113) may improve the fit by applying an appropriate voltage to the electrostatic clutch to generate an electrostatic force.

[0069]

[0070] Fig. 4 is an example drawing of a smart muscle band worn on an arm, and Fig. 5 is an example drawing of a smart muscle band worn on a leg.

[0071] As illustrated in FIGS. 4 and 5, the smart muscle band (100) may include a plurality of conductive pads (110). In addition, the area or location occupied by the conductive pads (110) and the arrangement of the plurality of conductive pads (110) may vary depending on the body part on which the band is worn. The location or spacing of the conductive pads (110) may be determined according to the location of the muscles of the body part. This is because the electrodes (111) for measuring electromyography and the electrodes (112) for stimulating muscles must contact the skin at the location of the muscles of the target body part.

[0072] In addition, the strain sensor (121) is placed in contact with the elastic portion (123), thereby generating strain data that changes according to the elongation and contraction of the elastic portion (123).

[0073] Meanwhile, the basic circumference measuring circuit (122) includes a plurality of male metal buttons (122-1), a plurality of female metal buttons (122-2), and a resistor (122-3) between the female metal buttons (122-2).

[0074] A male metal button (122-1) is arranged at one end of the band portion (120), and a female metal button (122-2) is arranged at the other end of the band portion (120). A plurality of female metal buttons (122-2) that can be coupled to one male metal button (122-1) may be provided along the long axis (circumferential direction) of the band portion (120). The female metal button (122-2) coupled to the male metal button (122-1) varies depending on the length of the circumference of the target body part. That is, since the contact point between the male metal button (122-1) and the female metal button (122-2) at which the basic circumference measuring circuit (122) is formed varies depending on the length of the circumference, the resistance value of the basic circumference measuring circuit (122) varies depending on the length of the circumference.

[0075]

[0076] FIG. 6 is a drawing showing an example of a fastening structure of a conductive pad and a band portion included in a smart muscle band according to the present invention and a mechanical configuration of the conductive pad.

[0077] The conductive pad (110) is divided into a band upper portion (band-upper) located at the upper portion of the band portion (120) and a band lower portion (band-lower) located at the lower portion of the band portion (120) in Fig. 6. The band upper portion includes a battery and an LED (Light-Emitting Diode) indicating the power on / off status.

[0078] The band upper part, the band part (120), and the band lower part are physically and electrically connected through the fixing part (115). That is, FIG. 6 is an example in which the fixing part (115) is a pogo pin. The fixing part (115) has a detachable structure, so that the conductive pad (110) and the band part (120) can be easily connected and separated. Since the conductive pad (110) and the band part (120) can be easily separated according to the detachable structure of the fixing part (115), there is an effect in which charging of the conductive pad (110) and cleaning of the band part (120) become convenient. In addition, since the fixed portion (115) serves as an electrical contact point between the conductive pad (110) and the band portion (120), it transmits an analog signal (strain data of the strain sensor (121), current signal (resistance value) of the basic circumference measurement circuit (122)) generated in the band portion (120) to the substrate (PCB) of the conductive pad (110) so that the controller (113) mounted on the substrate can receive the analog signal.

[0079]

[0080] FIG. 7 is a flowchart illustrating an operation method of a smart muscle band according to one embodiment of the present invention.

[0081] Referring to FIG. 7, the operating method of the smart muscle band (100) according to one embodiment of the present invention is based on a situation in which a user wears the smart muscle band (100) and exercises, and is composed of steps S210 to S260. The operating method of the smart muscle band (100) illustrated in FIG. 7 is according to one embodiment, and the steps of the operating method of the smart muscle band (100) according to the present invention are not limited to the embodiment illustrated in FIG. 7, and may be added, changed, or deleted as needed.

[0084] Step S230 is a step in which the conductive pad (110) determines the stimulation voltage to be applied to the muscle based on the muscle fatigue.

[0085] Step S240 is a step in which the conductive pad (110) applies the stimulation voltage to the muscle using the muscle stimulation electrode (112).

[0086] Steps S250 and S260 can be performed independently and in parallel with steps S210 to S240.

[0087] Step S250 is a step in which the band part (120) surrounding the circumference of the above body part transmits strain data of the built-in strain sensor (121) to the conductive pad (110).

[0088] Step S260 is a step in which the conductive pad (110) calculates the number of times the muscle is moved based on the strain data.
