[Technical Field]
[0001] The present disclosure relates to an electrode sheet, a cosmetic mask, and a cosmetic device, and in particular to an electrode sheet, a cosmetic mask, and a cosmetic device that can be adapted to the shape and size of human muscles. [Background technology]
[0002] Due to their flexibility and adaptability, flexible electrodes are widely known for their applications in the medical and healthcare fields. Recently, cosmetic devices have been developed that have electrode sheets that can treat various areas of the skin surface according to the user's needs (Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] International Publication No. 2024 / 080052 Summary of the Invention [Problem to be solved by the invention]
[0004] However, to achieve cosmetic effects, it is necessary to apply electrical stimulation to muscles as well as the surface of the skin. Human muscles vary in size and shape depending on the individual. In the above-mentioned conventional technology, electrode sheets are designed with a uniform size and shape, making it difficult to completely and accurately adapt to the shape of individual muscles. This makes it difficult to effectively enhance the muscle stimulation effect, the penetration effect of active ingredients into the skin, and the skin lifting effect.
[0005] Therefore, in order to solve the above-mentioned problems, the technology disclosed herein aims to provide an electrode sheet, beauty mask, and beauty device that can be adapted to the shape and size of human muscles. This allows the electrode sheet to adapt perfectly and accurately to the shape of each muscle, improving the efficiency of electrical signal transmission and further effectively enhancing the muscle stimulation effect, the penetration effect of active ingredients into the skin, and the effects related to skin lifting. [Means for solving the problem]
[0006] In one aspect, an electrode sheet for a beauty device is provided, which includes at least a conductive electrode and an insulating sheet body made of an adhesive and / or a flexible material having elasticity, the electrode being shaped to correspond to the shape of the muscle and fixed to the insulating sheet body, and the insulating sheet body having a connecting portion for detachably connecting to the beauty device. [Effects of the Invention]
[0007] According to the present disclosure, the electrode sheet can be perfectly and precisely adapted to each muscle, improving the adhesion between the electrode and the muscle. This improves the efficiency of electrical signal transmission, effectively enhancing the muscle stimulation effect, the penetration effect of active ingredients into the skin, and the effects related to skin lifting, and can provide excellent effects in medical devices, fitness equipment, etc. [Brief explanation of the drawings]

[0009] Each embodiment will be described in detail below with reference to the accompanying drawings. In the following description, the front side of the paper in the drawings will be referred to as the "front" or "top," and the back side of the paper will be referred to as the "back" or "bottom."
[0010] (Overall structure of electrode sheet) Fig. 1 is a plan view showing an outline of an electrode sheet according to the present embodiment. Fig. 2 is a cross-sectional view taken along line AA in Fig. 1. Fig. 3 is a plan view showing an exploded state of the electrode sheet in Fig. 1. Fig. 4 is a rear view of the conductive layer in Fig. 3.
[0011] The electrode sheet 1 according to this embodiment is used in a beauty device and is configured to be in contact with the skin of a user to provide a beauty-related effect to the user's skin. The electrode sheet 1 may also be used to provide an effect other than a beauty-related effect (for example, the effect of promoting transdermal absorption of medicines).
[0012] The beauty-related effect is optional and may include the reduction of sagging, tightening, fat burning, lifting, facial slimming, improving skin firmness, radiance, and moisture, or any combination of two or more thereof. The beauty-related effect may be a quantifiable effect or a non-quantifiable effect.
[0013] The electrode sheet 1 of this embodiment is configured to impart beauty-related effects to the user's skin by applying various outputs via electrodes that come into contact with the user's skin.
[0014] The electrode sheet 1 may include electrodes or groups of electrodes corresponding to the shape of muscles. These may be pad-shaped to cover a wide area, strip-shaped to fit specific areas, circular or oval-shaped to provide uniform stimulation over a small area, custom-shaped to fit specific areas, insole-shaped, or wearable for everyday wear. The muscle shapes refer to the shapes of muscles such as the frontalis, corrugator supercilii, orbicularis oculi, temporalis, levator labii alae nasus, levator labii superioris, orbicularis oris, oris, depressor labii inferioris, mentalis, procerus, nasal muscles, zygomaticus minor, zygomaticus major, masseter, buccinator, laughing muscles, depressor anguli oris, platysma, sternocleidomastoid, and platysma. The electrode sheet's shape, including electrodes or groups of electrodes corresponding to the shape of muscles, is designed according to the application and user needs. By selecting the appropriate shape, effective electrical stimulation of muscles can be achieved.
[0015] As shown in Figs. 1 to 4, the electrode sheet 1 of this embodiment includes an insulating sheet main body 2, a conductive layer 3, a bioadhesive layer 4, and a connection portion 5. In Fig. 1, the conductive layer 3 located on the back side (lower side) of the insulating sheet main body is shown with diagonal lines. In this embodiment, the connection portion 5 is located in the center of the insulating sheet main body 2, but the connection portion 5 is not limited to this. In Fig. 1, there are two conductive layers 3 and two connection portions 5, but the number of conductive layers 3 and two connection portions 5 is not limited to two.
[0016] The connection parts 5 are disposed on the surface of the electrode sheet 1 and serve to ensure electrical connection. The connection parts 5 are electrically connected to the conductive layers 3 at both ends of the electrode sheet 1. The connection parts 5 can be detachably connected to the main body of the cosmetic device, which will be described later.
[0017] The shape of the insulating sheet main body 2 shown in Figures 1 and 3 is an example for ease of understanding, and the shape of the insulating sheet main body 2 is not limited to this. The insulating sheet main body 2 shown in Figures 1 and 3 has a pair of generally rounded wide portions 21 and a narrow portion 22 connecting these wide portions 21, which are integrally formed. With this configuration, the insulating sheet main body 2 has a dumbbell-like shape in a plan view. The insulating sheet main body 2 shown in Figures 1 and 3 preferably has an electrode or electrode group fixed thereto that corresponds to the shape of a facial muscle, such as the masseter muscle.
[0018] Furthermore, a protruding ear 23 is formed at the end of one of the wide portions 21 opposite to the narrow portion 22. By gripping and manipulating this ear 23 with fingers or the like, the cosmetic device body 10 can be smoothly peeled (removed) from the user's skin surface.
[0019] The insulating sheet body 2 functions as a support layer that supports the conductive layer 3 and the bioadhesive layer 4. This insulating sheet body 2 is stretchable in any direction. Examples of the insulating sheet body 2 include resin sheets such as polyethylene terephthalate sheets, polypropylene sheets, and polyethylene sheets, thermoplastic elastomer sheets such as urethane-based thermoplastic elastomer sheets, rubber sheets such as nitrile rubber sheets and urethane rubber sheets, paper substrates, woven fabrics, nonwoven fabrics, foam sheets, and laminated sheets obtained by laminating these. The insulating sheet body 2 may be a non-stretchable polyethylene terephthalate sheet or the like.
[0020] The thickness of the insulating sheet body 2 is not particularly limited, but from the viewpoint of ensuring high conformability of the electrode sheet 1 to the skin surface, it is preferably 10 μm or more and 200 μm or less, and more preferably 25 μm or more and 150 μm or less.
[0021] The durometer hardness A of the insulating sheet body 2 is preferably in the range of 10 to 80, and more preferably in the range of 30 to 70. Having a hardness in this range improves the deformation (bending, stretching, etc.) characteristics of the insulating sheet body 2, and further increases the friction durability and mechanical strength.
[0022] The durometer hardness A of the insulating sheet body 2 is measured in accordance with JIS K 6253 (1997). Specifically, the durometer hardness A is obtained by preparing a sheet-like test piece using the insulating sheet body 2 and measuring the durometer hardness A of the test piece at 25°C.
[0023] The tear strength of the insulating sheet body 2 is preferably about 25 N / mm or more and 80 N / mm or less, and more preferably about 30 N / mm or more and 70 N / mm or less. This improves the durability of the insulating sheet body 2 during repeated use. It also makes it difficult for the insulating sheet body 2 to break even if it is made thin. This allows for greater design freedom while balancing the various properties of the insulating sheet body 2.
[0024] The tear strength of the insulating sheet body 2 is determined by preparing a crescent-shaped test piece using the insulating sheet body 2 and measuring the tear strength at 25°C in accordance with JIS K6252 (2001).
[0025] The breaking elongation of the insulating sheet body 2 is preferably about 100% to 2000%, more preferably about 200% to 1900%, and even more preferably about 300% to 1800%. This allows the insulating sheet body 2 to have a good balance of its various properties while improving its high stretchability and durability.
[0026] The breaking elongation of the insulating sheet body 2 can be determined in accordance with JIS K 6251 (2004) by preparing a dumbbell-shaped No. 3 test piece using the insulating sheet body 2, measuring its breaking elongation at 25°C, and calculating it as [gauge line travel distance (mm)] ÷ [initial gauge line distance (20 mm)] × 100.
[0027] The tensile strength of the insulating sheet body 2 is preferably about 5 MPa or more and 25 MPa or less, and more preferably about 10 MPa or more and 20 MPa or less. This improves the mechanical strength of the insulating sheet body 2 while balancing the various properties of the insulating sheet body 2. It also makes it possible to realize an insulating sheet body 2 with excellent durability that can withstand repeated deformation.
[0028] The tensile strength of the insulating sheet body 2 is obtained by preparing a dumbbell-shaped No. 3 test piece using the insulating sheet body 2 and measuring the tensile strength at 25°C in accordance with JIS K 6251 (2004).
[0029] The insulating sheet body 2 preferably has high gas permeability (high oxygen permeability, high water vapor permeability), which makes it less likely that the cosmetic device body 10 will damage the skin surface when treating the skin surface with the cosmetic device body 10.
[0030] Specifically, the oxygen permeability of the insulating sheet body 2 is not particularly limited, but is preferably about 1×10 3 cm 3 / m 2·24 h·atm or more, and more preferably about 2×10 3 cm 3 / m 2·24 h·atm or more.
[0031] The water vapor permeability of the insulating sheet body 2 is not particularly limited, but is preferably about 5 g / m 2 ·24 h ·atm or more, and more preferably about 10 g / m 2 ·24 h ·atm or more.
[0032] Two openings 222 are formed in the insulating sheet main body 2 (narrow width portion 22). In each opening 222, a part of the conductive layer 3, i.e., the connection portion 5, is exposed. The electrode sheet 1 is electrically and detachably connected to the cosmetic device main body via the exposed connection portion 5. The insulating sheet main body 2 can be provided with openings to allow the electrode portions to come into direct contact with the skin.
[0033] The conductive layer 3 is provided on the lower surface (one surface) of the insulating sheet main body 2. The conductive layer 3 may be disposed in direct contact with the insulating sheet main body 2, or may be disposed via an optional intermediate layer. Functions of the intermediate layer include improving the adhesion between the conductive layer 3 and the insulating sheet main body 2, reinforcing the conductive layer 3, and functions other than conducting electricity (for example, a heating function or a magnetic force imparting function, which will be described later).
[0034] As shown in Fig. 3, a pair of conductive layers 3 are provided on the left and right sides, and the two conductive layers 3 have approximately the same shape. Each conductive layer 3 includes three wiring sections 31, an electrode section 32 connected to one end of each wiring section 31, and an action site recognition section 7. By dividing and arranging the electrode sections 32 in this way, an electrode group corresponding to the shape of the muscle is formed.
[0035] Furthermore, the three wiring portions 31 join at the other end side to form a joining portion 33. The joining portion 33 further joins with a wiring portion 71 from the action site recognition portion 7 and is connected to the connection portion 5 protruding from the other end side. That is, the three wiring portions 31 and the wiring portion 71 are connected to the connection portion 5 while being isolated from each other by insulators. The three wiring portions 31 and the wiring portion 71 may be formed integrally with the connection portion 5 as long as they are isolated from each other by insulators.
[0036] Such a conductive layer 3 can also stretch in any direction. The conductive layer 3 can be made of, for example, a composite material (stretchable conductive material) containing a conductive filler and an elastomer. Examples of the conductive filler include carbon materials such as carbon nanotubes and carbon nanohorns, and metal materials such as gold, silver, copper, and nickel.
[0037] Examples of elastomers include thermoplastic elastomers such as polyamide-based thermoplastic elastomers, polyester-based thermoplastic elastomers, and urethane-based thermoplastic elastomers, as well as rubber materials such as ethylene propylene rubber, neoprene rubber, natural rubber, and silicone rubber. Such composite materials can be relatively easily produced by printing the conductive layer 3.
[0038] The thickness of the conductive layer 3 is not particularly limited, but from the viewpoint of ensuring high conformability of the electrode sheet 1 to the skin surface and the mechanical strength of the conductive layer 3, it is preferably about 1 μm or more and 50 μm or less, and more preferably about 5 μm or more and 25 μm or less.
[0039] When the resistance value (at 25 °C) of the entire conductive layer 3 and the bioadhesive layer 4 or the conductive layer 3 alone in the non-stretched state (natural state) is R1 [Ω], and the resistance value (at 25 °C) of the entire conductive layer 3 and the bioadhesive layer 4 or the conductive layer 3 alone at 50% elongation is R2 (Ω), it is preferably satisfied that 1 < R2 / R1 ≤ 20, more preferably satisfied that R2 / R1 ≤ 18, and even more preferably satisfied that R2 / R1 ≤ 16. With such a variation in the resistance value, current can be stably supplied to the skin surface.
[0040] When R1 is measured as the resistance value between the lower surface (skin side surface) of the bioadhesive layer 4 or, when the bioadhesive layer is omitted, the lower surface (skin side surface) of the conductive layer 3 and the upper surface (connection to the power source) of the connection portion 5, it is preferably about 1000 Ω or less, more preferably about 600 Ω or less, even more preferably about 500 Ω or less, particularly preferably about 400 Ω or less, and most preferably about 300 Ω or less. R2 is preferably about 5000 Ω or less, more preferably about 2000 Ω or less, and even more preferably about 1500 Ω or less.
[0041] In this specification, the stretchability of the conductive layer 3 is represented by the elongation rate when the conductive layer 3 is stretched in a certain direction. As the certain direction, for example, it can be the extending direction in which the wiring portion 31 extends. When the conductive layer 3 is stretched in this extending direction, the elongation rate is preferably about 10% or more, more preferably about 20% or more, even more preferably about 50% or more, and means that no disconnection occurs in the conductive layer 3 when stretched at such an elongation rate. The conductive layer 3 satisfying such conditions can be determined to have stretchability.
[0042] Also, as shown in FIGS. 1 and 3, a part of the wiring portion 31 and the electrode portion 32 is arranged along the outer edge of the insulating sheet body 2. Thereby, current can be supplied more uniformly to the muscle contacted by the electrode sheet 1.
[0043] In this embodiment, all of the multiple electrode units 32 have the same shape. However, some of the multiple electrode units 32 may have different shapes (in other words, some may have the same shape), or all of the multiple electrode units 32 may have different shapes from one another. That is, the multiple electrode units 32 may all be arranged to have the same shape, or may have electrodes of two or more different shapes, but the electrode units 32 must form an electrode or electrode group that corresponds to the shape of the muscle.
[0044] 1 and 3 are merely examples, and any electrode configuration is possible as long as the output waveform of AC stimulation can be applied to the user's muscles. Therefore, it is possible to apply various electrode configurations, such as a configuration of two concentric circular electrodes, a configuration of three concentric circular electrodes, a linearly arranged electrode configuration, a configuration of only one pair of point-like electrodes, and an electrode configuration including circular electrodes separated in the circumferential direction.
[0045] The bioadhesive layer 4 is provided on the opposite side of the conductive layer 3 from the insulating sheet main body 2. This bioadhesive layer 4 is configured to be attached to the user's skin surface. That is, the bioadhesive layer 4 has the function of holding the entire conductive layer 3 on the user's skin surface. Note that the bioadhesive layer 4 is one of the means having the function of holding the entire conductive layer 3 on the user's skin surface, and is not limited to this. Anything that has the function of holding the entire conductive layer 3 on the user's skin surface may be used, and examples include mask types.
[0046] The adhesive strength of the bioadhesive layer 4 varies slightly depending on the shape and size of the conductive layer 3, but is preferably about 0.5 N / 20 mm or more and 10 N / 20 mm or less, and more preferably about 1 N / 20 mm or more and 6 N / 20 mm or less. If the bioadhesive layer 4 has an adhesive strength in this range, the conductive layer 3 can be more securely held against the user's skin surface. The adhesive strength of the bioadhesive layer 4 refers to the adhesive strength when peeled off at an angle of 90° in accordance with the adhesive tape testing method of JIS Z 0237:2009.
[0047] As shown in Figure 3, a pair of bioadhesive layers 4 are also provided on the left and right sides, and the two bioadhesive layers 4 have approximately the same shape. Each bioadhesive layer 4 is large enough to encompass the conductive layer 3 in a plan view. By covering the entire conductive layer 3 with the bioadhesive layer 4 in this way, it becomes easier to supply current more uniformly to the skin surface. Note that the bioadhesive layer 4 can be provided with openings to allow the electrode portion to come into direct contact with the skin.
[0048] The bioadhesive layer 4 can be obtained by supplying the bioadhesive layer-forming material before gelation onto a release sheet to form a coating film and crosslinking it. The bioadhesive layer 4 may also be obtained by supplying the bioadhesive layer-forming material before gelation so that it covers the conductive layer 3 and crosslinking it. Examples of methods for crosslinking (polymerization) include methods in which the bioadhesive layer-forming material is heated, irradiated with light, or irradiated with radiation.
[0049] Such a bioadhesive layer 4 can also stretch in any direction. The bioadhesive layer 4 is preferably a gel having adhesive strength to the skin surface, particularly a highly water-containing adhesive gel. That is, the bioadhesive layer 4 is preferably in a gel state.
[0050] The water content of the high-water-content adhesive gel is not particularly limited, but is preferably about 10% by mass to 60% by mass, and more preferably about 15% by mass to 50% by mass. When the water content of the bioadhesive layer 4 is appropriate, swelling of the bioadhesive layer 4 is suppressed when used in combination with a topical skin preparation, and a decrease in the adhesive strength of the conductive layer 3 can be prevented or suppressed.
[0051] The highly hydrated adhesive gel is preferably a hydrogel containing, in addition to water, a polymer matrix and a plasticizer, and, if necessary, an electrolyte and a water-soluble polymer. The highly hydrated adhesive gel may also contain an active ingredient contained in a topical skin preparation, as described below. In this case, a plurality of fine needle-shaped protrusions (height: approximately 50 μm to 150 μm) may be formed on the skin-facing side of the bioadhesive layer 4. When the bioadhesive layer 4 is applied to the skin, the protrusions penetrate the skin surface, thereby promoting the penetration of the active ingredient into the skin tissue.
[0052] The thickness of the bioadhesive layer 4 is not particularly limited, but from the viewpoint of ensuring high conformability of the electrode sheet 1 to the skin surface and the mechanical strength of the bioadhesive layer 4, it is preferably 50 μm or more and 500 μm or less, and more preferably 100 μm or more and 350 μm or less.
[0053] The bioadhesive layer 4 is not limited to a configuration that covers the entire conductive layer 3, but may also be a configuration that covers part of the conductive layer 3. In the latter case, the electrode sheet 1 is attached so that the conductive layer 3 directly adheres to the skin surface in areas where the bioadhesive layer 4 is not present, and the bioadhesive layer 4 directly adheres to the skin in areas where the bioadhesive layer 4 is present. In this case, the presence of the bioadhesive layer 4 ensures that the electrode sheet 1 remains firmly attached to the user's skin surface, while a stronger current can be used to stimulate the skin surface and muscles where the conductive layer 3 directly adheres.
[0054] Furthermore, it is sufficient that at least a portion of the electrode sheet 1 is stretchable in any direction. Therefore, the electrode sheet 1 may be in an embodiment in which the insulating sheet main body 2 is stretchable but the conductive layer 3 is not necessarily stretchable, or in which the insulating sheet main body 2 and / or the conductive layer 3 include stretchable and non-stretchable portions, i.e., the electrode sheet 1 as a whole may include stretchable and non-stretchable portions.
[0055] Furthermore, the electrode sheet 1 may not be stretchable, but at least a portion of it may be flexible enough to conform to the skin surface, which allows for a wider range of materials to be used for the insulating sheet body 2 and the conductive layer 3.
[0056] The active site recognition unit 7 recognizes the active site of the electrode or electrode group and transmits information about the recognized active site to the cosmetic device. The active site recognition unit 7 accurately recognizes the user's muscle position and specific active site and transmits that information to the cosmetic device. This allows the cosmetic device to provide optimal treatment tailored to the user's needs. The active site recognition unit 7 is realized using technologies such as a color sensor (light sensor), resistance measurement, a magnetic sensor, measurement of the presence and placement pattern of magnets, reading IC tags, and image recognition. By combining these technologies, the active site recognition unit 7 accurately recognizes the active site of the electrode or electrode group and provides accurate information to the cosmetic device. This allows the electrode or electrode group of the electrode sheet 1 of the present invention to accurately contact the muscles corresponding to the shape of the electrode or electrode group, further effectively enhancing muscle stimulation, penetration of active ingredients into the skin, and skin lifting effects.
[0057] The action site recognition unit 7 transmits information about the recognized action site to the beauty device main body. When the electrode sheet 1 switches the action site, the beauty device main body's control unit (e.g., the control unit 14 described below) changes the output mode to suit the recognized action site. Furthermore, when a new action site is added, the control unit 14 must write the action site and its associated output information to the beauty device main body. This writing process is expected to be performed using remote update technology (including OTA technology, SOTA, FOTA, etc.) via a network. Specifically, OTA technology allows software updates to be performed remotely, allowing the action site recognition unit 7 to accurately recognize the new action site and appropriately switch the corresponding output mode. This method allows users to always use a beauty device that reflects the latest features and improvements, improving convenience. Furthermore, updates via a network reduce maintenance efforts and enable efficient device updates. Furthermore, as a security measure for remote updates, encrypted communication and authentication technology can be implemented to prevent unauthorized access and ensure secure information writing.
[0058] Human muscles vary in size and shape depending on the individual. Conventional electrode sheets were designed with a uniform size and shape, making it difficult to fully adapt to the shape of each individual muscle, resulting in insufficient adhesion between the electrodes and the muscle and reduced electrical signal transmission efficiency. The electrode sheet 1 is at least partially stretchable or flexible, allowing the electrode or electrode group to be adjusted to an appropriate position corresponding to the muscle shape. Furthermore, the electrode sheet 1 includes an active site recognition unit 7, allowing the position of the electrode or electrode group to be accurately adjusted. This allows the electrode sheet to fully and accurately adhere to the muscle, ensuring contact between the electrodes and the skin and improving electrical signal transmission efficiency.
[0059] (An example of a configuration in which the electrode sheet is connected to the beauty device body) 5A and 5B show an example in which a cosmetic device main body 10 is attached to the electrode sheet 1. The cosmetic device main body 10 shown in FIGS.
[0060] As shown in Figures 5A and 5B, the cosmetic device main body 10 has a pair of terminal portions 11 and a pin 101. Also, as shown in Figures 5A and 5B, the insulating sheet main body 2 has a pair of generally rounded wide portions 21 and a narrow portion 22 connecting these wide portions 21, which are integrally formed. Furthermore, a protruding ear portion 23 is formed on the end of one of the wide portions 21 opposite the narrow portion 22. By gripping and manipulating this ear portion 23 with fingers or the like, the cosmetic device main body 10 can be smoothly peeled (removed) from the user's skin surface.
[0061] The insulating sheet main body 2 is also formed with two through holes 221. By inserting the pins 101 into the through holes 221, the cosmetic device main body 10 can be positioned relative to the electrode sheet 1. That is, the cosmetic device 100 is configured by positioning the cosmetic device main body 10 using the pins 101 and the through holes 221 and connecting the cosmetic device main body 10 to the electrode sheet 1.
[0062] The cosmetic device main body 10 is attached to the longitudinal center portion (narrow portion 22) of the electrode sheet 1. A pair of pins 101 and a pair of terminal portions 11 protrude from the back surface of the cosmetic device main body 10. The pair of pins 101 are inserted into corresponding through holes 221 formed in the narrow portion 22 of the insulating sheet main body 2. The pair of terminal portions 11 are inserted into corresponding openings 222 formed in the narrow portion 22 of the insulating sheet main body 2 and connected to the connecting portion 5. In this way, the cosmetic device main body 10 is connected (fixed) to the electrode sheet 1.
[0063] With this configuration, in this embodiment, the cosmetic device main body 10 is detachably attached to the electrode sheet 1. Note that the cosmetic device main body 10 may also be fixed to the electrode sheet 1 so as not to be detachable.
[0064] When the cosmetic device main body 10 is configured to be detachable from the electrode sheet 1, it is preferable that the cosmetic device main body 10 be attached to the electrode sheet 1 by magnetic force. For example, by placing a permanent magnet inside or on the back surface of the cosmetic device main body 10, the permanent magnet can be attracted to the conductive layer 3 by magnetic force. Such an attachment / detachment mechanism has a simple configuration and also contributes to preventing the cosmetic device main body 10 from becoming larger.
[0065] Furthermore, when the cosmetic device main body 10 is configured to be attracted to the electrode sheet 1 by magnetic force, permanent magnets of different polarities (south pole and north pole) are placed on both the cosmetic device main body 10 and the electrode sheet 1, thereby preventing the cosmetic device main body 10 from being attached in the wrong direction relative to the electrode sheet 1.
[0066] The cosmetic device main body 10 may be configured to be attached to the longitudinal end of the electrode sheet 1. In this case, the wiring portion 31 and the wiring portion 71 are extended to the end of the insulating sheet main body 2, and the connection portion 5 is connected to the tip thereof. The terminal portion 11 is connected to the connection portion 5, and the cosmetic device main body 10 can perform various outputs to the electrode sheet 1. This configuration can also be adopted for electrode sheets 1 with other configurations described below.
[0067] Furthermore, it is desirable for the cosmetic device main body 10 to be as small as possible, and its mass must not hinder its close contact with the skin surface. For this reason, the cosmetic device main body 10 uses a flexible substrate to reduce its weight and size.
[0068] As shown in Fig. 5A, two operation buttons 12 are provided on the surface of the cosmetic device main body 10. These operation buttons 12 can change at least one of the amount of power supply or the supply pattern (mode). Note that changing the amount of power supply includes turning the power supply (power supply) on and off.
[0069] Fig. 6 is a block diagram showing the configuration of the beauty device main body 10 of Fig. 5A. Fig. 7 is an explanatory diagram of the control unit 14 built into the beauty device main body 10 according to this embodiment. Fig. 8 is a diagram showing an example of the hardware configuration of the control unit 14. Fig. 8 schematically shows peripheral devices 160 in association with the hardware configuration of the control unit 14.
[0070] The beauty device main body 10 is provided with a power supply unit 13, a control unit 14, and an electric circuit unit 15. The power supply unit 13 is configured to supply power to the control unit 14, the electric circuit unit 15, the electrode unit 32, and the action site recognition unit 7. This power supply unit 13 can be, for example, a dry cell, a solar cell, a fuel cell, a lithium ion secondary battery, an all-solid-state battery, a lithium polymer battery, etc. The power supply unit 13 may also be a connector to which a power cable can be connected.
[0071] The control unit 14 is electrically connected to the power supply unit 13 and to the electrode unit 32. The power supply unit 13 may be realized by an internal battery that can be mounted in the cosmetic device main body 10 and / or by an external power supply that can be connected to the cosmetic device main body 10. The control unit 14 may include a power supply circuit that generates various operating power sources based on the power supply unit 13. The control unit 14 may also include a general-purpose processor, a special-purpose processor, an integrated circuit, an ASIC (Application Specific Integrated Circuits), etc.
[0072] In the example shown in Figure 7, the control unit 14 includes a CPU (Central Processing Unit) 111, a RAM (Random Access Memory) 112, a ROM (Read Only Memory) 113, an auxiliary storage device 114, a drive device 115, and a communication interface 117, all connected by a bus 119, as well as a wired transceiver unit 125 and a wireless transceiver unit 126 connected to the communication interface 117.
[0073] The auxiliary storage device 114 is, for example, a hard disk drive (HDD) or a solid state drive (SSD), and is a storage device that stores data related to application software and the like.
[0074] The wired transceiver 125 includes a transceiver capable of communicating via a wired network. A peripheral device 160 is connected to the wired transceiver 125. However, some or all of the peripheral device 160 may be connected to the bus 119 or to the wireless transceiver 126. The peripheral device 160 may include the above-mentioned multiple electrode units 32 and a mobile terminal such as a user's smartphone. If the mobile terminal is included, the user may be able to configure various settings related to the cosmetic device main body 10 via the mobile terminal.
[0075] Wireless transceiver 126 is a transceiver capable of communicating using a wireless network. The wireless network may include a wireless communication network for mobile phones, the Internet, a Virtual Private Network (VPN), a Wide Area Network (WAN), etc. Wireless transceiver 126 may also include a Near Field Communication (NFC) unit, a Bluetooth (registered trademark) communication unit, a Wireless Fidelity (Wi-Fi) transceiver, an infrared transceiver, etc.
[0076] The control unit 14 may be connectable to a recording medium 116. The recording medium 116 is an example of a readable storage medium, and stores a predetermined program, such as a program for implementing the output control method of the cosmetic device according to the present invention. The program stored in the recording medium 116 is installed in the auxiliary storage device 114 of the control unit 14 via the drive device 115. The installed predetermined program can be executed by the CPU 111 of the control unit 14. For example, the recording medium 116 may be a recording medium that records information optically, electrically, or magnetically, such as a CD (Compact Disc)-ROM, a flexible disk, or a magneto-optical disk, or a semiconductor memory that records information electrically, such as a ROM or flash memory. The recording medium 116 does not include a carrier wave.
[0077] The control unit 14 generates one or more output waveforms that can be applied to the skin or muscles via the multiple electrode units 32 based on the power supply unit 13. Furthermore, a program for realizing the output control method for the cosmetic device 100 according to the present invention is, for example, a program that provides electrode position information based on active site information from the active site recognition unit 7 and operates the processor to output a frequency or the like applied to the confirmed active site. That is, the program may be any program that processes the active site information from the active site recognition unit 7, provides the electrode position, and operates the processor to output a frequency or the like applied to the confirmed active site so that the electrode or electrode group completely and accurately fits the muscle. The confirmed active site is the active site determined by the user to have the electrode completely and accurately fit the corresponding muscle shape by adjusting the electrode sheet 1.
[0078] When the electrode sheet 1 switches its active site, the control unit 14 recognizes the active site based on the active site information from the active site recognition unit 7. Specifically, the control unit 14 analyzes the data provided by the active site recognition unit 7 and identifies the new active site with which the electrode sheet 1 is in contact. Through this identification process, the control unit 14 confirms that the electrode sheet 1 is placed in the appropriate position and that it will effectively act on the correct site.
[0079] Furthermore, when the electrodes are completely and accurately attached to the corresponding muscle shape, the control unit 14 notifies the user of the confirmed active site by an alarm or the like. This allows the user to recognize that the electrode sheet 1 is properly positioned and being used effectively. The alarm in this embodiment is in the form of vibration feedback. Alternatively, this alarm may be provided in the form of feedback such as a visual display or audio notification, and the output mode is changed to suit the recognized active site. Furthermore, when a new active site is added, the control unit 14 must write the active site and its associated output information to the beauty device main body. This writing process is performed using remote update technology (including OTA technology, SOTA, FOTA, etc.) via a network.
[0080] The control unit 14 also has the function of changing the output mode to suit the recognized action area, thereby providing the optimum output for each action area, enabling effective cosmetic treatment.
[0081] Furthermore, when a new action site is added, the control unit 14 must write the action site and the associated output information to the beauty device main body 10. This writing operation is performed using remote update technology (including OTA technology, SOTA, FOTA, etc.) via a network. This method allows the user to always use the latest data and functions, and maintains and improves the performance of the beauty device main body 10.
[0082] (First Example) Fig. 8 shows an example of how to use the electrode sheet according to Example 1. Fig. 9 is a plan view showing the electrode sheet 1 according to Example 1. The electrode sheet 1 according to Example 1 has electrodes or electrode groups corresponding to the temporalis muscle and orbicularis oculi muscle of the face, and is structured to effectively provide electrical stimulation to specific facial regions.
[0083] In the following description, the front side of the paper in Fig. 9 will be referred to as the "front" or "top," and the back side of the paper in Fig. 9 will be referred to as the "back" or "bottom." In Fig. 9, the conductive layer 3 located on the back side of the insulating sheet main body 2 is indicated by hatching.
[0084] The electrode sheet 1 according to the first embodiment is designed to be placed from the temporalis muscle to the orbicularis oculi muscle of the face. The electrode sheet 1 is elongated and curved in the middle to form a C- or L-shape. An electrode sheet 1 having such a structure can be brought into contact with, for example, the temporalis muscle and orbicularis oculi muscle areas at once, facilitating treatment of the skin and muscles in these areas. Furthermore, as shown in FIG. 8, when the muscles of a user's face are symmetrically distributed, it is preferable to use two electrode sheets 1 according to the first embodiment symmetrically. That is, when the muscles are symmetrically distributed in the human body, it is preferable to use a pair of electrode sheets 1 or an electrode sheet 1 having multiple electrode units 32 including a first electrode and a second electrode so that the multiple electrode units 32 correspond to the symmetrical muscle shapes. In this case, the first electrode may have the shape of the muscle on the left side of the muscle, and the second electrode may have the shape of the muscle on the right side of the muscle.
[0085] The insulating sheet body 2 and the conductive layer 3 are shaped so as to be positioned from the temporalis muscle to the orbicularis oculi muscle of the face. The upper electrode portion 32 of the conductive layer 3 is designed to correspond to the shape of the temporalis muscle, and the lower electrode portion 32 is designed to correspond to the shape of the orbicularis oculi muscle. The proportion of the electrode portion 32 corresponding to the muscle shape is generally preferably 50% or more, more preferably approximately 70 to 90%. In this embodiment, for example, the electrode portion 32 is preferably formed to have a shape corresponding to the shape of the orbicularis oculi muscle. Furthermore, the tip portion 35 of each conductive layer 3 on the side opposite the connection portion 5 is mesh-shaped. Having such a shape of the tip portion 35 allows the current applied to the skin surface to be dispersed in that area (in other words, prevents current concentration). As a result, the user can experience a mild physical sensation (muscle stimulation), i.e., a physical sensation that is not uncomfortable. The other configurations of the electrode sheet 1 according to the first embodiment are the same as those of the electrode sheet 1 shown in FIGS. 1 to 3.
[0086] The electrode sheet 1 is designed to provide optimal electrical stimulation by identifying the area of action using the control unit 14. This arrangement allows for effective stimulation of the temporalis muscle and orbicularis oculi muscle. Therefore, the electrode sheet 1 has a structure optimized for providing effective electrical stimulation to specific areas of the face, allowing the user to enjoy maximum cosmetic benefits.
[0087] (Second Example) Fig. 10 shows an example of how to use the electrode sheet 1 according to Example 2. Fig. 11 is a plan view showing the electrode sheet 1 according to Example 2. The electrode sheet 1 according to Example 2 has electrodes or electrode groups corresponding to the shapes of the zygomatic minor muscle, zygomatic major muscle, orbicularis oris muscle, and laughing muscle of the face, and has a structure for effectively providing electrical stimulation to specific facial regions.
[0088] In the following description, the front side of the paper in Fig. 11 will be referred to as the "front" or "top," and the back side of the paper in Fig. 11 will be referred to as the "back" or "bottom." In Fig. 11, the conductive layer 3 located on the back side of the insulating sheet body 2 is indicated by hatching.
[0089] The electrode sheet 1 according to the second embodiment is designed to be placed from the orbicularis oris and laughing muscles to the zygomatic minor and zygomatic major muscles of the face. The electrode sheet 1 according to the second embodiment is broadly divided into two parts. The electrode sheet 1 in FIG. 11 has an overall trefoil-like shape, with a rounded upper portion and a wider lower portion. The upper portion of the electrode sheet 1 is designed to be placed from the orbicularis oris muscle to the laughing muscles of the face. The lower portion of the electrode sheet 1 is designed to be placed from the zygomatic minor to the zygomatic major muscles of the face. The electrode sheet 1 configured in this way can be brought into contact with the zygomatic minor, zygomatic major, orbicularis oris, and laughing muscles of the face all at once, making it easy to treat the skin or muscles in those areas.
[0090] The insulating sheet body 2 and conductive layer 3 are shaped so that they are positioned from the orbicularis oris and laughter muscles to the zygomatic minor and zygomatic major muscles of the face. The electrode portion 32 is designed to correspond to the shape of the zygomatic minor and zygomatic major muscles from the broad lower portion of the conductive layer 3 to the rounded upper portion. The electrode portion 32 in the broad lower portion of the conductive layer 3 is also designed to correspond to the shape of the orbicularis oris and laughter muscles. The conductive layer 3 may have a mesh-like structure, which can disperse the current applied to the skin surface in that area (in other words, prevent current concentration). As a result, the user can experience a mild physical sensation (muscle stimulation), i.e., a physical sensation that is not uncomfortable. The other configurations of the electrode sheet 1 according to the second embodiment are the same as those of the electrode sheet 1 shown in Figures 1 to 3.
[0091] The electrode sections 32 of the electrode sheet 1 according to the second embodiment are arranged vertically, and can effectively apply electrical stimulation to the zygomatic minor, zygomatic major, orbicularis oris, and laughing muscles of the face. By using the electrode sheet 1 in this way, the electrodes can be efficiently attached to specific facial muscles, and EMS technology can be used to promote a lifting effect, which is particularly effective in lifting the area around the mouth and reducing nasolabial folds.
[0092] The electrode sheet 1 has been described above as being applicable to a type having a bioadhesive layer 4, but the technology according to the present disclosure is not limited to this. The electrode sheet 1 can be configured to have a shape corresponding to the shape of the muscles in each part of the body, and can be applied to a mask type, a hair band type, a shoulder type, a pendant type, a tabletop type, a handheld type, etc.
[0093] (Third Example) Below, an electrode sheet mask 200 will be described as an example of a mask type that applies the electrode sheet 1. FIG. 12 is a diagram schematically illustrating the use of an electrode sheet for an electrode sheet mask of Example 3. FIG. 13 is a plan view illustrating the electrode sheet mask 200 of Example 3. The electrode sheet 1 for the electrode sheet mask 200 of Example 3 has electrodes or electrode groups corresponding to the shapes of the stylohyoid muscle, masseter muscle, and mylohyoid muscle, and is structured to effectively provide electrical stimulation to specific muscle regions. In particular, the mask type is more effective than the four-layer bioadhesive type in areas that are relatively prone to movement, such as around the neck.
[0094] The electrode sheet mask 200 is composed of a main body 201, two fixing portions 202, two fixing portions 205, a plurality of holes 203, 204, and two electrode sheets 1. The main body 201 is bilaterally symmetrical and has a shape that spreads out from the center toward both sides. As shown in Fig. 13, the two fixing portions 202, two fixing portions 205, two holes 203, and two electrode sheets 1 are arranged bilaterally symmetrically in the main body 201.
[0095] The main body 201 is made of a material that is both flexible and durable, and may be made of the same material as the insulating sheet body 2. The fixing parts 202 are arranged at both ends of the lower part of the main body 201. The fixing parts 205 are arranged at both ends of the upper part of the main body 201. The fixing parts 202 and 205 are made of a padding material, and a material that is excellent in flexibility, durability, stability, and comfort is selected.
[0096] The fixing part 202 serves to firmly fix the electrode sheet mask 200 to the lower part of the face. The fixing part 205 serves to firmly fix the electrode sheet mask 200 to the upper part of the face. By stably fixing the fixing parts 202 and 205, the electrode part 32 can be positioned accurately, providing effective electrical stimulation.
[0097] The two holes 203 are arranged symmetrically on the left and right sides of the electrode sheet mask 200, and are provided at positions corresponding to the ears. The two holes 204 are arranged symmetrically on the top and bottom sides in the center of the electrode sheet mask 200, and are provided at positions corresponding to the mouth and chin. The multiple holes 203, 204 improve the breathability of the electrode sheet mask 200, prevent pressure on the ears, and distribute pressure around the chin and mouth, thereby reducing discomfort even when used for long periods of time.
[0098] The two electrode sheets 1 according to the third embodiment are designed to be positioned along the contours of the stylohyoid muscle, masseter muscle, and mylohyoid muscle. Each electrode sheet 1 has a butterfly-like shape, arranged symmetrically. Specifically, it has wing-like sections that extend vertically and narrow in the center. The wing-like sections of the electrode contact the facial skin over a wide area, transmitting electrical stimulation evenly. An electrode sheet 1 configured in this way can be brought into contact with the stylohyoid muscle, masseter muscle, and mylohyoid muscle at the same time, making it easy to treat the skin or muscle in those areas. Furthermore, the electrode portions 32 on each electrode sheet 1 may be positioned to correspond to the contours of the stylohyoid muscle and masseter muscle, or the contours of the stylohyoid muscle and mylohyoid muscle.
[0099] Furthermore, the main body portion 201 according to the third embodiment has the same function as the insulating sheet main body 2. In this case, the shape of the conductive layer 3 is formed so as to be disposed from the stylohyoid muscle to the masseter muscle and mylohyoid muscle. The electrode portion 32 on one side of the conductive layer 3 is designed to correspond to the shapes of the stylohyoid muscle and masseter muscle, and the electrode portion 32 on the other side is designed to correspond to the shapes of the stylohyoid muscle and mylohyoid muscle. Furthermore, the tip of each conductive layer 3 is mesh-shaped. By having such a tip shape, the current applied to the skin surface in that area can be dispersed (in other words, current concentration can be prevented). As a result, the user can experience a mild physical sensation (muscle stimulation), i.e., a physical sensation that is not unpleasant. The rest of the configuration is the same as that of the electrode sheet 1 shown in Figures 1 to 3.
[0100] The electrode sheet 1 according to the third embodiment is designed to provide optimal electrical stimulation by identifying the target area using the control unit 14. The specific placement of the electrode units 32 enables effective stimulation of the stylohyoid, masseter, and mylohyoid muscles. Specifically, the stylohyoid muscle is stimulated by reducing muscle tension and promoting blood circulation, improving muscle flexibility and recovery. The masseter muscle is stimulated by reducing muscle tension and reducing pain, alleviating symptoms of temporomandibular joint disorder and bruxism. The mylohyoid muscle is stimulated by increasing muscle strength and providing rehabilitation, which is expected to improve swallowing function and pronunciation. This improves jaw function and facial muscle health, supporting a more comfortable daily life.
[0101] (Fourth Example) An electrode sheet mask 300 will be described below as an example of a mask type that applies the electrode sheet 1. FIG. 14 is a plan view showing the electrode sheet mask 300 of Example 4. The electrode sheet mask 300 is worn by wrapping it around the face. The electrode sheet 1 of the electrode sheet mask 300 of Example 4 has electrodes or electrode groups that correspond to the shape of the area around the jaw, specifically the suprahyoid muscle group and infrahyoid muscle group, and is structured to effectively provide electrical stimulation to specific muscle areas.
[0102] The electrode sheet mask 300 has a main body portion 301, a fixing portion 302, a plurality of hole portions 303 and 304, and two electrode sheets 1. The main body portion 301 is formed symmetrically. As shown in FIGS. 14 and 15 , the two hole portions 303 and the two electrode sheets 1 are arranged symmetrically in the main body portion 301.
[0103] The main body part 301 is made of a material that is both flexible and durable. The fixing part 302 is disposed at one end of the main body part 301. The fixing part 302 is made of a padded material, and a material that is excellent in flexibility, durability, stability, and comfort is selected.
[0104] The fixing part 302 serves to firmly fix the electrode sheet mask 300 to the face. By stably fixing the fixing part 302, the electrode parts 32 of the electrode sheet 1 are positioned accurately, enabling effective electrical stimulation to be provided.
[0105] The two holes 303 are arranged symmetrically on the left and right sides of the electrode sheet mask 300, at positions corresponding to the ears. The hole 304 is arranged in the center of the electrode sheet mask 300, at a position corresponding to the mouth. The multiple holes 303, 304 improve the breathability of the electrode sheet mask 300, and can reduce discomfort even when used for long periods of time.
[0106] The two electrode sheets 1 according to the fourth embodiment are designed to be arranged along the contours of the suprahyoid and infrahyoid muscles. The two electrode sheets 1 are arranged symmetrically. The electrodes contact a wide area of the facial skin and transmit electrical stimulation evenly. An electrode sheet 1 having such a configuration can be brought into contact with the areas of the suprahyoid and infrahyoid muscles all at once, making it easy to treat the skin or muscles in those areas. The electrode sections 32 may be arranged on each electrode sheet 1 to correspond to the contours of the suprahyoid and infrahyoid muscles.
[0107] The electrode sheet 1 also has an insulating sheet body 2, a plurality of electrode portions 32, and a plurality of wiring portions 31. The insulating sheet body 2 is, for example, a polyethylene terephthalate sheet that does not have elasticity. The thickness of the insulating sheet main body 2 is, for example, 0.075 mm, taking into consideration the conformability of the insulating sheet main body 2 to the skin. However, the thickness of the insulating sheet main body 2 is not limited to 0.075 mm. The thicker the insulating sheet main body 2, the less conformable it is to the skin, and the thinner the insulating sheet main body 2, the less easily it can be attached to the electrode sheet 1, so the thickness of the insulating sheet main body 2 can be adjusted as appropriate. The plurality of electrode portions 32 are, for example, silver electrodes that use silver and have almost no resistance. The plurality of wiring portions 31 are, for example, carbon sheets that use carbon, and the resistance when electricity is applied can be adjusted by including impurities inside the carbon sheets. In addition, the carbon sheet is provided with an insulating coating (not shown) on the portion that is exposed to the skin. The electrode sheet 1 has two silver electrodes spaced apart in the left-right direction, with a carbon sheet between them to connect the two silver electrodes, and these silver electrodes and carbon sheets are integrally provided in multiple pairs (for example, two pairs) spaced apart (vertically) in parallel to each other. In this way, the electrode (conductive layer 3) is formed by the multiple electrode portions 32 and the multiple wiring portions 31.
[0108] The tip of each electrode is mesh-shaped or the like. By having such a tip, the current applied to the skin surface can be dispersed (in other words, the current can be prevented from concentrating) in that area. As a result, the user can experience a mild physical sensation (muscle stimulation), i.e., a physical sensation that is not uncomfortable.
[0109] The electrode sheet 1 according to the fourth embodiment is designed so that the beauty device main body 10 is attached to the beauty device main body attachment portion 10a, and the control unit 14 of the beauty device main body 10 identifies the area of action and provides optimal electrical stimulation. The specific arrangement of the electrode portion 32 enables effective stimulation of the suprahyoid and infrahyoid muscles. The suprahyoid muscles include, for example, the mylohyoid, anterior digastric belly, posterior digastric belly, and stylohyoid. The infrahyoid muscles include, for example, the thyrosternohyoid, sternohyoid, sternothyroid, and omohyoid. Electrical stimulation of the suprahyoid and infrahyoid muscles reduces facial volume and sharpens the jawline.
[0110] 16 to 20 are diagrams showing variations in the usage types of the electrode sheet according to this embodiment. Each of these types is designed to suit the needs and lifestyle of the user, and by effectively positioning the electrodes, it provides a variety of beauty and health benefits.
[0111] FIG. 16 shows an example in which the electrode sheet according to this embodiment is applied to a hair band type. The hair band type has a structure in which electrodes are placed on the scalp and temporal region when worn on the head. Electrodes placed inside the hair band directly contact specific points on the scalp and temporal region, providing effective stimulation. The hair band is made of a flexible material and is designed to fit the shape of the head.
[0112] FIG. 17 shows an example of the electrode sheet according to this embodiment applied to a shoulder strap type. The shoulder strap type is an electrode sheet worn over the shoulder.
