Description

Technical Field

[0001] The present invention relates to a necklace capable of stimulating the brain, an ornament, a brain stimulation device, and a method of using the necklace, and more particularly to a necklace capable of generating alpha waves when worn. Background Art

[0002] Brainwaves have various wavelengths: γ (gamma) waves above 30 Hz, β (beta) waves between 14 and 30 Hz, α (alpha) waves between 7 and 14 Hz, θ (theta) waves between 4 and 7 Hz, and δ (delta) waves below 4 Hz (see, for example, Patent Document 1). Gamma waves are often produced during periods of anxiety and excitement, beta waves are more likely to occur during thinking and stress, alpha waves are more likely to occur during meditation, quiet time, and concentration, theta waves are more likely to occur during periods of drowsiness and confusion, and delta waves are more likely to occur during coma and sleep.

[0003] Alpha waves are further categorized into three stages based on their wavelength. The first stage, at 12-13 Hz, represents efforts to relax; the second stage, at 10-12 Hz, produces intuition or flashes of thought; and the third stage, at 8-10 Hz, is known as the state of emptiness (no thoughts, no thoughts), which is most likely to occur when one reaches a state of emptiness. Furthermore, measurements of the brainwaves of Zen monks and individuals experienced in meditation have revealed that alpha waves originating from the frontal lobe are significantly higher. On the other hand, it is said that frequent mental states, such as those associated with stress, can lead to a greater number of health problems.

[0004] In addition, in existing brain science research, for diseases related to brain activity, symptom improvement is sometimes achieved through current stimulation (for example, patent documents 1 to 3). In existing technologies, when current stimulation is applied to brain activity, a current with the same phase as the measured brain wave is applied, or a current is applied without considering the phase of the intrinsic brain wave. That is, due to the influence of capacitive conduction, a time deviation occurs until the brain wave reaches the detection position of the electroencephalogram meter arranged on the outer surface of the head from the potential generating source of the brain wave inside the brain, thereby causing a phase delay of the brain wave. Therefore, in existing methods, the effect of current stimulation is not sufficient, or it may cause an opposite effect when the phase is opposite to the phase of the intrinsic brain wave. Therefore, in the method of patent document 3, the brain is stimulated with a signal corresponding to the deviation of the phase of the observed brain wave.

[0011] Patent Document 5: Japanese Utility Model Registration No. 3115353 Summary of the Invention

[0012] Technical problem to be solved by the invention

[0013] Existing technologies (e.g., Patent Documents 1-3) place electrodes on the head to detect brain waves. While these can be used in front of such a detection device, they are not suitable for daily use (particularly while walking, doing housework, working, etc.). The inventors of this application have developed a necklace-type device, rather than such a device that cannot be used in daily life, and the necklace-type device developed by the inventors is disclosed in Patent Document 4. The device disclosed in Patent Document 4 is a necklace-type device that emits and transmits alpha waves.

[0014] In addition, a device for forcing brainwaves is disclosed in Patent Document 5. The device for forcing brainwaves in Patent Document 5 can stimulate from outside the body by a pulse current of a specific frequency, guiding one side to the frequency. Specifically, an earphone-shaped wearing part (helmet) is used so that the electrodes of the wearing part are in contact with the temples of the head and the front of the ears, and a pulse current is applied, thereby using the human body as a medium and allowing the pulse current to pass through. The pulse current passes through the muscle layer and skin surface of the human body, so that the muscles inside the human body vibrate, and through the vibration, the cells resonate. In addition, although there is a brainwave filter to prevent the entry of harmful substances, the electrical stimulation is not controlled by the blood-brain barrier and reaches the brain tissue, and no side effects are produced.

[0015] The brainwave forced guidance device of Patent Document 5 applies pulsed current by placing electrodes of an earphone-shaped wearable portion in contact with the temples and the front of the ears. This makes it unsuitable for constant wear and, moreover, highly conspicuous, potentially disrupting daily life. On the other hand, the necklace-shaped device developed by the inventors of the present application (disclosed in Patent Document 4) does not present this inconvenience, does not disrupt daily life, and is highly convenient.

[0016] However, the inventors of this application conducted research and development and discovered the following technical problems. First, the device disclosed in Patent Document 4 can be used constantly. Therefore, due to prolonged contact between the electrodes and the skin, the connection between the electrodes and the tubes (the necklace chain covered with silicone rubber tubes) that secure them becomes brittle, sometimes preventing the electrodes from being firmly secured. Furthermore, the device disclosed in Patent Document 4 applies a pulsed current at a frequency of 10.8 Hz to the back of the neck, but this does not provide the maximum effect, and this also needs to be addressed.

[0017] The present invention has been completed in view of the above situation, and its main purpose is to provide a necklace, an ornament and a brain stimulation device that can stimulate the brain and are suitable for long-term use.

[0042] Effects of the Invention

[0043] In the necklace of the present invention, the alpha wave generating body that generates the alpha wave pulse current includes a filter electrically connected to the pulse current generating unit and attenuating frequencies higher than the alpha waves. The electrodes are secured to the necklace wire by an electrode securing member. Therefore, the filter can filter out harmonics (overtones) generated by the pulse current generating unit, thereby attenuating frequencies exceeding the alpha waves (noise), allowing the alpha waves to enter the user through the electrodes. Consequently, brain stimulation can be achieved, resulting in a more reliable alpha wave effect. Furthermore, since the materials of the electrodes (metal) and the necklace wire are different, securing the electrodes (metal) to the necklace wire can cause them to fall off or shift out of position due to prolonged use (e.g., prolonged daily use). However, in the present invention, the electrodes are secured to the necklace wire by the electrode securing member, preventing such electrode problems (e.g., electrode degradation, falling off, or shifting). Therefore, the necklace of the present invention can provide a necklace that stimulates the brain and is suitable for prolonged use. BRIEF DESCRIPTION OF THE DRAWINGS

[0108] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. In the following drawings, components and locations that perform the same function are designated by the same reference numerals to simplify the description, and duplicate descriptions may be omitted or simplified. Furthermore, while the dimensional relationships (length, width, thickness, etc.) in the various figures generally satisfy their intended dimensional relationships, even though six-sided views can be extracted from the drawings, these may not always accurately reflect the actual dimensional relationships.

[0109] In addition, matters other than those specifically mentioned in this specification, that is, matters necessary for implementing the present invention, can be understood as design matters by those skilled in the art based on the existing technology in this field. The present invention can be implemented based on the contents described in this specification and the drawings and the technical common sense in the field. In addition, the present invention is not limited to the following embodiments.

[0110] Figure 1 The structure of the necklace 100 according to the embodiment of the present invention is shown. Figure 2 The figure shows how the necklace 100 according to this embodiment is worn. Figure 3 The electrodes 20 are shown when a user wears the necklace 100 according to this embodiment (around the back of the neck). Figure 4 The necklace 100 of this embodiment is placed on the mounting table 50. Figure 4 The front structure of the necklace 100 of this embodiment is shown. Figure 5 The back structure of the necklace 100 according to this embodiment is shown.

[0111] The necklace 100 of this embodiment is composed of an alpha wave generating body 10 that generates an alpha wave pulse current, a necklace wire 30 connected to the alpha wave generating body 10, and an electrode 20 provided on a portion of the necklace wire 30. In the structure of this embodiment, as shown in FIG. Figure 1 and Figure 3 As shown, the electrode 20 is fixed by an electrode fixing member 25 ( 21 , 22 ) connected to a necklace wire 30 .

[0112] Figure 6 : is a block diagram schematically showing the structure of the alpha wave generating main body 10 in the necklace 100 of this embodiment. Figure 6As shown, the alpha wave generating body 10 of this embodiment includes a pulse current generating unit 41 that generates alpha wave pulse currents, and an alpha wave pass filter or alpha wave selection filter 42 that is electrically connected to the pulse current generating unit 41 and attenuates frequencies higher than the alpha waves. The pulse current generating unit 41 of this embodiment includes a semiconductor integrated circuit element (microcomputer, IC) that generates the pulse currents and is, for example, comprised of a circuit board on which such a semiconductor integrated circuit element (microcomputer, IC, MPU) is mounted. Furthermore, the pulse current generating unit 41 is not limited to using a semiconductor integrated circuit element (microcomputer, IC) as long as it can generate alpha wave pulse currents; other elements (e.g., a crystal oscillator, etc.) may also be used. In this embodiment, the pulse current generating unit 41 is constructed using a semiconductor integrated circuit element (microcomputer, IC) because this facilitates frequency control.

[0113] In the structure of this embodiment, the filter 42 selectively passes frequencies in the alpha wave region. The filter (alpha wave pass filter) 42 in this embodiment is, for example, a low-pass filter (LPF) that attenuates frequencies higher than the alpha wave. The filter 42 in this embodiment can also be a band-pass filter that selectively passes frequencies of the alpha wave. Here, the term "cutting off (eliminating)" frequencies higher than the alpha wave also includes a band-pass filter that cuts off (eliminating) both frequencies higher than the alpha wave and frequencies lower than the alpha wave, and is described using the term "low-pass filter." Alternatively, a low-pass filter can be referred to as a high-cut filter. The pulse current generating unit (IC) 41 and the filter (low-pass filter) 42 are disposed on a circuit board 40. In the structure of this embodiment, an LED (light-emitting diode) 44 is disposed on the circuit board 40. Furthermore, the circuit board 40 is connected to an output terminal 43. Furthermore, the circuit board 40 is electrically connected to a battery 45 (e.g., a secondary battery or a primary battery).

[0114] The alpha wave generating unit 10 generates a pulsed current with a frequency in the alpha wave range (from 8 Hz to 13 Hz, or from 7 Hz to 14 Hz). The alpha wave generating unit 10 of this embodiment generates an alpha wave pulsed current with a frequency of 10.8 Hz (±1 Hz). The alpha wave pulsed current with a frequency of 10.8 Hz belongs to the 10-12 Hz range (the second stage) of the alpha wave wavelength, which produces intuition and flashes of thought. Furthermore, as a characteristic of the human body, achieving high performance during a runner's high (runner's high) or secreting serotonin, which promotes the secretion of male hormones, female hormones, and growth hormones, is also a state of a relaxed brainwave (alpha wave). The necklace 100 of this embodiment selects the 10.8 Hz average alpha wave from the age of 10 to 20, which is the period when serotonin is most secreted.

[0115] like Figure 1 As shown, the alpha wave generating main body 10 of the present embodiment has a shell 11, and a window (light-emitting portion) 12 for displaying the light of an LED (or light-emitting element) is provided on the shell 11. The shell 11 of the present embodiment is made of resin, for example, polycarbonate (PC). In addition, the resin material constituting the shell 11 may also be a material other than polycarbonate (PC) (for example, polypropylene, polyethylene, polystyrene, vinyl chloride resin, ABS resin, epoxy resin, PET, acrylic acid, etc.). In addition, the window 12 of the present embodiment is formed by providing a light-transmitting or light-transmitting resin to the opening provided in the shell 11. When the necklace 100 of the present embodiment is in operation, the window (LED light-emitting portion) 12 emits light in red, blue (or white, yellow, green, etc.).

[0116] The necklace wire 30 is a wire having a conductor inside. Moreover, a resin coating portion 31 is formed on the surface of the necklace wire 30. In the structure of the present embodiment, the necklace wire 30 is a wire in which a metal conductor (for example, copper, aluminum, etc.) is coated with an insulator (for example, rubber, resin). In a preferred example, the necklace wire 30 of the present embodiment uses a wire having a silicone rubber coating hose provided on the outside of the metal conductor. The necklace 100 of the present embodiment is of waterproof (life waterproof) specification, and the waterproof effect is improved by using a waterproof material (rubber, resin) to coat the metal conductor. In addition, in a preferred example, the silicone rubber coating hose has the function of protecting the alpha wave pulse current flowing in the conductor from the influence of external noise.

[0117] One end of the necklace wire 30 of this embodiment is fixed to the alpha wave generating body 10 in an irremovable manner. Figure 1As shown, the housing 11 of the alpha wave generating body 10 of this embodiment consists of a cylindrical central portion 11a, a tapered portion 11b continuously connected to the central portion 11a, and a wire fixing portion 16 located at the distal end of the tapered portion 11b. The wire fixing portion 16 of this embodiment is made of an elastomer or rubber (e.g., nitrile rubber (NBR)). The necklace wire 30 extends from the center of the wire fixing portion 16. Furthermore, the wire fixing portion 16 is configured to seal the alpha wave generating body 10 in order to achieve the waterproof (daily waterproof) function of the necklace 100. This daily waterproofing (daily waterproofing, 2-3 atmospheres of pressure waterproofing) is effective for waterproofing against the expected "wet" conditions in daily life, such as light rain, sweating, or washing one's face.

[0118] The other end of the necklace wire 30 of this embodiment is provided with a socket portion 15 that can be attached to and detached from the alpha wave generating main body 10. Figure 2 As shown in FIG, the detachable connector 15 is a structure that can be inserted into the end (recess) of the alpha wave generating main body 10. Specifically, the connector 15 includes an inserting portion 15a and a switch portion 15b. Figure 1 In the state shown in FIG. 1 , when the switch portion 15b of the connector portion 15 is pressed with a finger, as shown in FIG. Figure 2 As shown, the joint portion 15 is in a state of being detached. Figure 2 In the state shown, when the insertion portion 15a of the connector 15 is inserted into the recess of the alpha wave generating main body 10 (housing 11), it becomes Figure 1 The connector 15 is provided with a wire fixing portion 16 , and the necklace wire 30 extends from the center of the wire fixing portion 16 .

[0119] The length of the necklace wire 30 in this embodiment is, for example, 300 mm to 700 mm (in one example, the length from the tip of the connector 15 to the end of the housing 11 of the alpha wave generating body 10 is 500 mm (±50 mm)). The thickness (diameter) of the necklace wire 30 is, for example, 50 mm (±20 mm). However, the length and thickness (diameter) of the necklace wire 30 can be appropriately adjusted to suit the intended use and design (design conditions).

[0120] In the structure of the present embodiment, an electrode 20 is provided on a portion of the necklace wire 30. Moreover, the electrode 20 is electrically connected to the conducting wire of the necklace wire 30. The electrode 20 of the present embodiment is made of metal. In a preferred example, the electrode 20 is made of stainless steel (or aluminum) so that it is not easily rusted by sweat or rain. The electrode 20 of the present embodiment has a cylindrical shape (or a cylindrical shape). The diameter of the electrode 20 is larger than the diameter of the necklace wire 30, so that the electrode 20 can be more easily in contact with the user's skin. The diameter of the electrode 20 of the present embodiment is, for example, 8 mm (±3 mm). In addition, the length of the electrode 20 is, for example, 25 mm (±5 mm). However, the diameter and length of the electrode 20 can be appropriately sized according to the intended use and the designed purpose (design conditions).

[0121] In the structure of this embodiment, a plurality of electrodes 20 are provided. In the example shown in the figure, two electrodes 20 are arranged on opposite sides of the alpha wave generating body 10. In a preferred example, the electrodes 20 are provided in bilaterally symmetrical positions. In the example shown in the figure, the distance from each of the two electrodes 20 to the alpha wave generating body 10 (the length of the necklace wire 30) is equal (for example, 150 mm (±20 mm)). In addition, the distance between one electrode 20 (the first electrode) and the other electrode 20 (the second electrode) (the length of the necklace wire 30) is 40 mm (±20 mm). In addition, three or more electrodes 20 can be provided, and in some cases, there can be only one electrode 20.

[0122] like Figure 1 and Figure 3 As shown, the electrodes 20 (first and second electrodes) are fixed to the necklace wire 30 by an electrode fixing member 25. Furthermore, the electrodes 20 (first and second electrodes) are connected by the electrode fixing member 25 so that there is no gap between the electrodes 20 and the surface (resin coating, silicone rubber hose) 31 of the necklace wire 30. While the fixing member 25 in this embodiment is made of a resin material, other materials may be used as long as they are insulators.

[0123] The electrode fixing part 25 of this embodiment is composed of a hemispherical cover part 21 and a protrusion 22 provided at the bottom of the cover part 21. Moreover, the protrusion 22 is provided on the cover part 21 in a manner to fix the end of the electrode 20. The necklace wire 30 is inserted into the center of the apex of the cover part 21. Here, the bottom of the cover part 21 is a portion located below the center of the apex (top) of the cover part 21, and does not refer to the bottom in the direction of gravity (vertical direction). In addition, the hemispherical shape of the cover part 21 is not limited to a hemisphere (half of a sphere) in the geometric sense, as long as it is a shape (conical shape) that fills the gap between the diameters of the electrode 20 (large diameter) and the necklace wire 30 (small diameter).

[0124] The protrusion 22 of the electrode fixing part 25 in this embodiment is an arc part (a curved strip part or a curved rectangular part) along the cylindrical shape of the electrode 20. In the structure of this embodiment, one electrode fixing part 25 is composed of one cover part 21 and two protrusions 22. The electrode fixing part 25 (protrusion 22) contacts one surface (for example, the upper surface) and the opposite surface (for example, the lower surface) of the surface of the electrode 20, fixing the electrode 20 to the necklace wire 30 (31). In this embodiment, two protrusions 22 are provided in the electrode fixing part 25, but one protrusion (annular part) can be provided, or a structure with three or more protrusions 22 can be provided. In addition, a recess 23 is formed in the cover part 21 of the electrode fixing part 25 in the illustrated example. By forming the recess 23 in the cover part 21, the thickness of a part of the cover part 21 becomes thinner, so that the cover part 21 has a spring function (elasticity). Thus, even if the electrode 20 (metal) and the electrode fixing member 25 (resin) are made of different materials, stable fixation can be ensured by utilizing the spring function (elasticity).

[0125] The material (metal) of the electrode 20 of this embodiment and the material of the necklace wire 30 (31) are different materials, and their thermal expansion coefficients are also different, and the speed of degradation is also different. Therefore, if the electrode 20 (metal) is simply arranged on the necklace wire 30 (31) and fixed, the electrode may fall off or deviate from the specified position due to long-term use (for example, long-term use in daily life). On the other hand, in the structure of this embodiment, since the electrode 20 is fixed to the necklace wire 30 by the electrode fixing member 25, such electrode defects (electrode performance degradation, falling off, deviation, etc.) can be prevented. Therefore, it is possible to form a structure (fixed structure) of the electrode 20 suitable for long-term use.

[0126] like Figure 4 As shown, in the necklace 100 of this embodiment, a mounting platform 50 on which the alpha wave generating body 10 can be mounted can be provided. The mounting platform 50 of this embodiment is a wireless charging platform capable of wireless charging. In the structure of this embodiment, a secondary battery for driving (for example, a lithium polymer battery) is built into the alpha wave generating body 10, and a coil for wireless charging is provided. In addition, a coil for wireless charging is provided on the mounting platform 50 (wireless charging platform), and charging can be performed by placing the alpha wave generating body 10 on the mounting platform 50. A power cord 52 (power cord, USB cable, etc.) can be installed on the mounting platform 50, and power can be obtained through the power cord 52. In addition, a light-emitting window (LED light-emitting unit) 55 that indicates the status of the action (work) is provided on the mounting platform 50. By flashing the light-emitting window, the charging and other actions can be confirmed by light.

[0127] By configuring the necklace 100 of this embodiment to be wirelessly charged, the charging terminal can be omitted, thereby enabling a more waterproof structure. Furthermore, as long as the structure is waterproof, the necklace 100 is not limited to being wirelessly charged. It can also be configured to be charged by connecting a power cord, or it can be configured to use a disposable battery without charging.

[0128] Figure 7 An example of a cross-sectional structure of the alpha wave generating main body 10 of the present embodiment is schematically shown. In the structure of the present embodiment, a circuit board 40 is arranged in the housing 11 of the alpha wave generating main body 10. Electronic components and circuits 49, LED elements 44, etc., which constitute a semiconductor integrated circuit element (pulse current generating unit, microcomputer, IC) 41, a filter (low-pass filter) 42, etc. are mounted (installed) on the circuit board 40. The filter (low-pass filter) 42 can be composed of an electronic component chip or circuit for a low-pass filter. In addition, a battery (lithium-ion secondary battery) 45 electrically connected to the circuit board 40 is provided in the housing 11. In addition, a coil 47 for electromagnetic induction connection with the coil of the mounting table 50 (wireless charging station) is provided in the housing 11.

[0129] In the structure of this embodiment, a battery 45, a circuit board 40, and a coil (a coil for wireless charging) 47 are housed in a stacked state within the housing 11. Specifically, in the illustrated example, the battery 45 (preferably a lithium polymer battery) is positioned above the circuit board 40. To account for expansion of the battery 45 (due to heat during operation), a gap D (e.g., 1.2 mm ± 1 mm) is provided between the battery 45 and the housing 11. Furthermore, a cushioning material (e.g., a slow-rebound sponge (low-rebound sponge)) 46 is provided below the battery 45 to mitigate the effects of battery 45 expansion. Furthermore, a coil (a coil for wireless charging) 47 is positioned below the circuit board 40. A spacer 48 is provided on the circuit board 40 to ensure space for the coil 47. By storing the alpha wave generator 10 (housing 11) in this stacked state, the device can be miniaturized (thinned), reducing the burden of the device being constantly attached to the body (around the neck) in daily life.

[0130] Furthermore, the housing 11 is provided with an insertion recess 19 into which the connector 15 is inserted. In the configuration of this embodiment, a magnet 18 is provided on the connector 15. An element (e.g., a Hall effect IC) is provided on the housing 11 side to detect (probe) the magnet 18 of the connector 15. The element (e.g., a Hall effect IC) that detects the magnet 18 can detect whether the wire 30 is connected (i.e., whether the connector 15 is inserted and secured).

[0131] Next, refer to Figures 8 to 13An example of the structure and operation of the necklace 100 of this embodiment will be described. Note that this description is for illustrative purposes only, and a person skilled in the art will readily understand that other structures and operations can be employed.

[0132] exist Figure 8 3 shows a combination of the necklace 100 and the mounting base (wireless charging base) 50 according to this embodiment, schematically illustrating the state where the α wave frequency (10.8 Hz) is emitted from the electrode 20 .

[0133] Figure 9 This is a block diagram for explaining the structure of the alpha wave generating main body 10 (circuit board 40 ) of this embodiment. The alpha wave generating main body 10 is shown together with the circuit board of the mounting base (wireless charging base) 50 .

[0134] like Figure 9 As shown, various components are arranged on the circuit board 40 that constitutes the alpha wave generating unit 10. Specifically, the circuit board 40 includes a microcomputer 41, a filter (low-pass filter) 42, a crystal oscillator (8 MHz), a voltage divider resistor, LEDs 44 (red and white), a Hall effect IC, a charging IC, a rectifier, an LDO (Low Drop Out) regulator, a POR (Power On Reset) circuit, a thermistor, and a magnet. Furthermore, a battery 45 is electrically connected to the circuit board 40. A coil 47 is connected to the rectifier of the circuit board 40.

[0135] exist Figure 9On the circuit board 40 shown, the microcomputer 41 functions as a pulse current generator 41 (a signal generator of a predetermined frequency) that generates an alpha wave pulse current. This generates an alpha wave pulse current (10.8 Hz or 10.85 Hz), which is output from the output terminal 43 as a signal output through the filter 42 and flows through the necklace wire 30 to the electrode 20. The output frequency (sine wave) of the alpha wave pulse current in this example is a minimum of 10.80 Hz, a maximum of 10.89 Hz, and an average of 10.85 Hz. In addition, the output voltage of the alpha wave pulse current in this example is, for example, 30 μV to 120 μV, preferably 55 μV to 60 μV (±5%). In addition, when the alpha wave voltage is 55 μV, it is confirmed that the effect of the necklace 100 of this embodiment can be obtained, but the effect may be weakened when the air (external atmosphere) is dry. Experiments have confirmed that when the alpha wave voltage is 60 μV (±5%), the effect of the necklace 100 of this embodiment can be reliably obtained even in dry air. In addition, the output current is 0.003 microamperes (0.003 μA) (±5%).

[0136] Here, harmonics (so-called overtones) can be generated as noise in the alpha wave pulse current generated by the pulse current generator 41 (microcomputer, microcomputer, MCU). For example, the overtone (doubled) of a 10Hz alpha wave becomes 20Hz, which falls within the wavelength range of beta waves and cannot be denied the possibility of causing tension. Furthermore, the tripled alpha wave of 10Hz becomes 30Hz, which falls within the wavelength range from beta waves to gamma waves and cannot be denied the possibility of causing anxiety or excitement. If it is temporary noise, such as that during an EEG test, it can be said that this noise has little effect. However, the necklace 100 of this embodiment is a necklace that can be worn at all times. Therefore, even if there is no actual effect of such noise, the possibility of such an effect, however small, is intended to be reduced. In the structure of this embodiment, by providing a filter (low-pass filter) 42 that attenuates frequencies higher than alpha waves, noise with the potential for such an effect is blocked, and the advantageous effects of the necklace 100 of this embodiment are reliably exerted. In this embodiment, for example, a filter (low-pass filter) 42 that cuts off frequencies above 15 Hz can be set, but the frequencies above which the frequencies are cut off (the frequencies exceeding which the frequencies are cut off) can be determined by appropriately manufacturing a prescribed filter based on the filter design according to specific specifications, conditions, and characteristics, and determining the cutoff frequency (the frequency that is significantly attenuated).

[0137] Figure 10 1 is a block diagram for explaining the structure of the circuit board of the mounting table (wireless charging table) 50 of this embodiment. Figure 10As shown, it is equipped with a microcomputer (MPU), a thermistor, an LED (red), a Hall IC, a current detection resistor, a coil driver (CoilDriver), a matching network (matching circuit), a POR (Power On Reset, power-on reset), and a POR circuit. The microcomputer is provided with a timer function for charging for 1 hour. The circuit board of the mounting table 50 is connected to a coil (electromagnetic induction coil - for contactless charging / wireless use), and the coil is used to connect the charging terminal to the charging terminal by electromagnetic induction. Figure 9 The coil 47 of the illustrated alpha wave generating main body 10 (circuit board 40) supplies electric power, thereby performing wireless power supply.

[0138] Figure 11 Indicates the LED action when the power is ON (connected) and the LED action when the power is in operation. Among them, OFF means the power is off. Figure 11 As shown, when the power cord 30 is connected and the power is turned on, LED (white) 44 and LED (red) 44 flash alternately for two seconds from the time the power is turned on, notifying the user that the necklace 100 is operating normally. During operation, LED (white) 44 flashes (here, flashes twice) every specified seconds (e.g., every five seconds) to notify the user that the necklace 100 is operating normally. Furthermore, when the remaining charge of battery (accumulator) 45 decreases (below 3.5V), LED (red) 44 flashes (here, flashes once) every specified seconds (e.g., every five seconds) to notify the user that the remaining charge is low.

[0139] Figure 11 LED operation indicates error conditions. When an error occurs, if the circuit board temperature of circuit board 40 reaches 60°C or higher, LED (red) 44 flashes and an alarm sounds. At this point, 10.8 Hz transmission is stopped. Errors are resolved by plugging and unplugging power cord 30. This constitutes the system (circuit).

[0140] Figure 13 This chart illustrates the LED operation of the mounting platform (wireless charging platform) 50. When the power cord (USB) 52 of the mounting platform 50 is connected and the alpha wave generating unit 10 is placed on the mounting platform 50, power is supplied and charged. A timer is used to supply and charge the device for a predetermined time (here, one hour). Furthermore, while the power cord (USB) 52 of the mounting platform 50 is connected, the LED (red) 44 illuminates.

[0141] Figure 11 LED operation indicates errors in the mounting platform 50. When an error occurs, if overcurrent is detected and / or the circuit board temperature exceeds 60°C, LED (red) 44 flashes and an alarm sounds. At this time, power is shut off. The error is resolved by plugging and unplugging the power cord (USB) 52. This constitutes the system (circuit).

[0142] In the necklace 100 of this embodiment, the alpha wave generating body 10 that generates the alpha wave pulse current includes a filter 42 (a low-pass filter that attenuates frequencies higher than alpha waves) electrically connected to a pulse current generating unit (microcomputer, MPU) 41. Furthermore, the electrode 20 is secured to the necklace wire 30 by an electrode securing member 25. Consequently, the filter (low-pass filter) 42 blocks harmonics (overtones) generated by the pulse current generating unit, thereby attenuating frequencies exceeding the alpha waves (noise), allowing the alpha wave frequencies to be input to the user from the electrode 20. Consequently, the brain can be stimulated, and the alpha wave effect can be more reliably generated. Furthermore, the material (metal) of the electrode 20 and the material of the necklace wire 30 (31) are different materials. When the electrode 20 (metal) is fixed to the necklace wire 30 (31), the electrode may fall off or deviate from the specified position due to long-term use (for example, long-term use in daily life). However, in the structure of this embodiment, the electrode 20 is fixed to the necklace wire 30 by the electrode fixing member 25, so such electrode problems (electrode performance degradation, falling off, deviation, etc.) can be prevented. Therefore, according to the necklace 100 of this embodiment, a necklace that can stimulate the brain and is suitable for long-term use can be realized.

[0143] Next, refer to Figures 15 to 35 The effects of the necklace 100 according to this embodiment will now be described. To experimentally measure the effects of the necklace 100 according to this embodiment, comparisons were conducted between the necklace 100 according to this embodiment (Example), a placebo product identical in shape to the necklace 100 but without any function (Comparative Example), and a normal state (not worn). The experiments conducted included muscle reflex testing (front), muscle reflex testing (back), back strength measurement, latissimus dorsi muscle activity measurement, and EEG measurement.

[0144] Fourteen subjects were tested in a single-blind, crossover test (only the subjects were blinded) wearing the Example and the Comparative Example (placebo product). The test was blinded to the subjects, who were unaware of which product was the Example. However, to prevent habit formation, the product initially worn was tested simultaneously for both odd-numbered and even-numbered subjects.

[0145] To ensure consistent test (measurement) conditions, a rest period of at least 3 minutes was set before each measurement, and measurements were performed after resting. Specifically, after the measurement was completed without wearing the device (normal state), the product (Example, Comparative Example) was handed over and the device was worn and rested for 3 minutes before the measurement began.

[0146] Figure 15 The results of comparison between the comparative examples and the examples are shown (Table 1). Figure 16The results of the comparison between the unworn and the example are shown in Table 2. "Mean" is the average value, "SD" is the standard deviation, and "SP", "S / P (%)", and "p-value" are statistical terms. Further explanation is given below.

[0147] Figures 17 to 19 The results of the muscle reflex test (front) (table), the situation of the muscle reflex test (front), and the results of the muscle reflex test (front) (graph) are shown respectively. Figure 18 As shown, in the muscle reflex test (front), the measurement supervisor (weight 90 kg) applied a uniform load downward to the subject's crossed hands, enough to leave one foot in the air, and measured the time until the subject could no longer maintain the upright position.

[0148] like Figure 17 and Figure 19 As shown, the value of the comparative example was 1.82 (seconds), while the value of the example was 9.31 (seconds), and a statistically significant difference was confirmed.

[0149] Figures 20 to 22 The table shows the results of the muscle reflex test (back), the situation of the muscle reflex test (back), and the results of the muscle reflex test (back) (graph). Figure 20 As shown, in the muscle reflex test (back), the measurement supervisor (weight 90 kg) applied a uniform load downward to the subject's crossed hands, enough to leave one leg in the air, and measured the time until the subject could no longer maintain an upright position.

[0150] like Figure 20 and Figure 22 As shown, the value of the comparative example was 1.70 (seconds), while the value of the example was 8.66 (seconds), and a statistically significant difference was confirmed.

[0151] Figures 23 to 25 The following table shows the results of the back (spine) strength test, the situation of the back strength test, and the results of the back strength test (chart). Figure 24 As shown, measurements were performed using a specialized device for measuring back strength.

[0152] like Figure 23 and Figure 25 As shown, the value of the comparative example was 94.1 (kg), while the value of the example was 106.8 (kg), and a statistically significant difference was confirmed.

[0153] Figures 26 to 28 The results of measuring the activity of the latissimus dorsi muscle (table), the situation of measuring the activity of the latissimus dorsi muscle, and the results of measuring the activity of the latissimus dorsi muscle (graph) are respectively shown. Figure 27As shown, measurements were performed under the same load conditions using a dedicated device for measuring back strength.

[0154] like Figure 26 and Figure 28 As shown, the value of the comparative example was 0.033245 (mv), while the value of the example was 0.033463 (mv), and a statistically significant difference was confirmed.

[0155] Figures 29 to 31 The results of brain wave measurement (table), the situation of brain wave measurement, and the results of brain wave measurement (graph) are shown respectively. Figure 30 As shown, measurements were performed under the same load conditions using dedicated equipment for EEG measurement.

[0156] like Figure 29 and Figure 31 As shown, the value of the comparative example was 35.42768 (meditation), while the value of the example was 50.67913 (meditation), and a statistically significant difference was confirmed.

[0157] Regarding muscle reflex test, back strength, and relaxation effect, after each measurement, the situation was listened to and evaluated by questionnaire (secondary evaluation). The evaluation was set as 10 levels from 1 to 10 points, with the higher the score, the better the tendency. Figures 32 to 35 Shown in. Figures 32 to 35 The results are a table of the questionnaire results for the three items, a graph of the results for the questionnaire (muscle reflex), a graph of the results for the questionnaire (back), and a graph of the results for the questionnaire (relaxation).

[0158] like Figures 32 to 35 As shown, in all three items, the product (necklace) of the example scored higher than that of the comparative example.

[0159] According to the results of these experiments, wearing the necklace 100 of this embodiment (Example) showed statistically significant differences in all measurement items, including muscle reflex tests (front / back), back strength, latissimus dorsi activity, and brain wave measurement (meditation). In addition, the questionnaire survey (secondary evaluation / subjective evaluation) also confirmed that the difference was significant, even when compared with not wearing the necklace and wearing the comparative example (placebo product).

[0160] In particular, the results of the muscle reflex test, which showed significant differences, showed that the iliopsoas muscle (deep muscle) near the lumbar spine (characteristic of parasympathetic nerve activity only at S-2) was significantly strengthened (since electromyometry cannot measure deep areas, the latissimus dorsi muscle was used instead). It is speculated that the use of the embodiment (necklace 100) caused a weak current to flow to the medulla oblongata, leading to parasympathetic nerve dominance, which had a positive impact on physical function and tremor suppression. Furthermore, it is speculated that the "serotonin secretion" characteristic of the parasympathetic nerve dominance state also leads to pain relief, irritability suppression, and improved concentration.

[0161] The structure of this embodiment achieves a necklace 100 that can stimulate the brain and is suitable for long-term use. However, the technical concept of this embodiment is not limited to necklace 100; it can be applied to any device in which the electrodes 20 can contact the skin. Specifically, the structure of the aforementioned embodiment (the structure of necklace 100) can be applied to decorative items (ornaments attached to the body), specifically, bracelets (including watches), anklets, and other decorative items. Furthermore, even if it is not called a decorative item (necklace, etc.), the structure of the aforementioned embodiment (the structure of necklace 100) can be configured as a product (wearable item) that serves as a brain stimulation device. While it is more effective when attached to the body near the head, as in the present embodiment, the necklace 100 is more effective when attached to the body near the head. However, even in areas such as the wrist, brain stimulation can be achieved through the skin. Experiments conducted by wrapping the necklace 100 around the wrist confirmed the effects achieved by the necklace 100. Furthermore, in addition to the test results of the aforementioned examples, when the necklace 100 was worn by three patients with Parkinson's disease, the results showed that within approximately five minutes, all three patients stopped shaking their hands and feet and were able to walk smoothly. It was also confirmed that the hands and feet were strong enough to lift heavy objects. Furthermore, when the necklace 100 was removed, the shaking began again after approximately five minutes, suggesting an effect comparable to deep brain stimulation (DBS) therapy. Furthermore, when the necklace 100 was worn by a patient with eosinophilic granulomatosis with polyangiitis (EGPA), a type of collagen disease, it was shown that those who were unable to walk without a cane were able to walk without a cane. Furthermore, prolonged wearing of the necklace 100 resulted in hair growth from a thinning head.

[0162] In addition, the necklace 100 (ornament, brain stimulation device) of this embodiment can be modified as follows. In the structure of this embodiment, the necklace 100 can adopt a structure that allows the length of the necklace wire 30 to be adjusted. As such a structure, an adjustment mechanism for adjusting the length of the necklace wire 30 can be provided in the alpha wave generating body 10. The adjustment mechanism for the length of the necklace wire 30 can be a mechanism for winding the necklace wire 30, and the necklace wire 30 can be adjusted by winding. Alternatively, the adjustment mechanism can be configured to lengthen or shorten the necklace wire 30 using a mechanism similar to squeezing lipstick. Furthermore, the necklace wire 30 can be configured to allow the necklace wire 30 to be replaced with different lengths as a mechanism for adjusting the length of the necklace wire 30. Even when an adjustment mechanism for adjusting the length of the necklace wire 30 is provided, it is preferable that the necklace 100 (or the alpha wave generating body 10) has a waterproof structure (a substantially sealed structure).

[0163] In addition, in the necklace 100 (ornament, brain stimulation device) of the above embodiment, Figure 6 The pulse current generating unit 41 shown includes a semiconductor integrated circuit element (microcomputer, IC, or Figure 9 '41' etc.), and the semiconductor integrated circuit element can be configured to include a mode unit for switching the action mode. The action mode in the mode unit can be at least one selected from a normal mode, an athlete mode, a learning mode, a disease recovery mode, a child mode, an adult mode, an elderly mode, and a relaxation mode. The mode unit for switching the action mode (action mode switching unit) can be configured in software by causing the semiconductor integrated circuit element to execute a program for performing such an action. In addition, the mode unit for switching the action mode (action mode switching unit) can also be configured in hardware.

[0164] In one example of this embodiment, the normal mode among the operational modes is a standard operational mode (standard pulse current generation and operational mode), typically a mode that can be used throughout daily life. The athlete mode is an operational mode suitable for improving athletic ability. The learning mode is an operational mode suitable for improving concentration for learning. The disease rehabilitation mode is an operational mode suitable for alleviating symptoms (e.g., pain, leg immobilization) of a person with a specific disease. The child mode is a mode suitable for developing and improving children's abilities and concentration. The adult mode is a mode suitable for developing and improving adults' abilities and concentration. The elderly mode is a mode suitable for developing and improving the abilities and concentration of the elderly. For the elderly, the average alpha wave (10.8 Hz) level in the 10-20 age group, the earliest period of serotonin secretion, is relatively lower than in younger people. Therefore, a mode (e.g., current and voltage for generating alpha waves) that takes this into account is preferably used. The relaxation mode is a mode suitable for relaxing, such as mindfulness-based stress reduction and meditation. The mode unit of the semiconductor integrated circuit device in this embodiment has the function of switching between at least two of the aforementioned operational modes, for example, switching between the normal mode and the learning mode. Alternatively, the mode unit in this embodiment has the function of switching between normal mode, child mode, adult mode, and elderly mode. Furthermore, the mode unit in this embodiment has the function of switching to, for example, normal mode, study mode, and athlete mode for students and young people. Alternatively, the mode unit in this embodiment has the function of switching to other action modes (for example, disease rehabilitation mode, elderly mode, etc.) without setting the normal mode. In addition, in actual applications, the average value of the object (for example, the elderly) can be considered, and the conditions of the action mode (elderly mode) (for example, the output, voltage, current, time, etc. of the alpha wave pulse current) can be appropriately set to appropriate conditions, or the conditions (for example, the output, voltage, current, time, etc. of the alpha wave pulse current) can be appropriately set to appropriate conditions according to the characteristics of a single person (the user of the necklace 100 (ornament, brain stimulation device) of this embodiment).

[0165] In the mode unit of this embodiment, a timer unit that controls the time for generating alpha wave pulse current in the action mode can also be provided. This timer unit can be configured as software by executing a program for performing such an action through a semiconductor integrated circuit element. In addition, the timer unit can also be configured as hardware. By providing and using this timer unit, the alpha wave pulse current can be stopped at a certain time, and the action can be stopped without manual operation, which is convenient. In addition, it also helps to prevent the battery (for example, lithium ion secondary battery 45 ( Figure 7Furthermore, when used to improve concentration during study, the timer unit can be used to control study time (e.g., 30 minutes, 45 minutes, etc.), which is convenient to use. Furthermore, during athlete training, the timer unit can be used to control training time (e.g., 30 minutes, 45 minutes, etc.), which is convenient to use. The timer unit can also be configured to generate a sound or vibration when the timer expires (a configuration implemented by a program).

[0166] In addition, a cumulative time calculation unit that accumulates and calculates the time when the alpha wave pulse current is generated in the action mode can also be provided in the mode unit of the semiconductor integrated circuit element of this embodiment. Such a cumulative time calculation unit can be constructed in software by causing the semiconductor integrated circuit element to execute a program that performs such an action. In addition, the cumulative time calculation unit can also be constructed in hardware. By providing and using such a cumulative time calculation unit, it is possible to know how long the alpha wave pulse current has been flowing, which is convenient to use. The cumulative time calculation unit has the function of calculating and displaying the total usage time, and can also calculate and display the usage time of 1 day, 1 week, 1 month, etc. In addition, it can also have the function of displaying a comparison with the previous day, comparison with the previous week, comparison with the previous month, etc.

[0167] In addition, the necklace 100 (ornament, brain stimulation device) of this embodiment may also include a communication unit that can communicate with an external communication device. As an example, the alpha wave generating main body 10 of this embodiment includes a communication unit (wireless communication device) that can communicate with an external communication device. Such a communication unit is, for example, a device for realizing Bluetooth communication (Bluetooth device) or a device for realizing Wi-Fi (wireless network, Wireless Fidelity) communication (Wi-Fi device). Moreover, the action mode in the mode unit may also be configured to be switched by the operation of an external communication device. In the configuration example of this embodiment, the external communication device is, for example, a smartphone (or tablet terminal, notebook PC, etc.). Moreover, the action mode in the mode unit is configured to be able to perform a switching operation by an application installed on a smartphone (or tablet terminal, etc.). When such a structure is adopted, the screen (liquid crystal panel, organic EL panel, etc.) of the external communication device (smartphone, etc.) can display the action of the necklace 100 (ornament, brain stimulation device) of this embodiment. In addition, the display of the above-mentioned timer unit (and / or cumulative time calculation unit) can be displayed on the screen of an external communication device (smartphone, etc.), and its operation can be performed through the external communication device (smartphone, etc.).

[0168] In addition, the necklace 100 (ornament, brain stimulation device) of this embodiment can also be configured to be operated not only from an external communication device (smartphone, etc.), but also from the mounting base 50 ( Figure 4 The necklace 100 (ornament, brain stimulation device) of this embodiment can also be operated by both an external communication device (smartphone, etc.) and the mounting base 50. When the necklace 100 (ornament, brain stimulation device) of this embodiment is operated by an external communication device (smartphone, etc.) and the mounting base 50, it is easier to improve the waterproofness (sealing) of the waterproof structure of the alpha wave generating main body 10 than when an operation button (or operating element · terminal, operation panel, etc.) is provided on the alpha wave generating main body 10, so it is preferred.

[0169] The present invention has been described above by way of appropriate embodiments, but such description is not limiting and various modifications are possible.
