The mask pack 100 is applied to the user's skin when various skin beauty ingredients are applied to the surface and attached to the user's face. Here, the skin cosmetic ingredient may include various vegetable materials, animal extract materials, hydrogels, ocher and polysaccharides, or mixtures thereof, and includes all substances that can be used as skin cosmetic ingredients as well as the above-described embodiments.

The mask pack 100 includes all forms that can be attached to the user's face.

The thermoelectric element 200 is coupled to the outer surface of the mask pack 100 to generate a microcurrent. More specifically, when the mask pack 100 to which the thermoelectric element 200 is coupled is attached to the user's face, a temperature difference between the user's body heat and the mask pack 100 occurs, and accordingly, the lower electrode and the upper portion of the thermoelectric element 200 A temperature difference also occurs between the electrodes, and the thermoelectric element 200 converts this temperature difference into electrical energy to generate a fine current. The generated microcurrent flows through the mask pack 100 and the user's face. Due to the microcurrent, the skin beauty ingredient applied to the mask pack 100 can penetrate deeper into the user's face. Hereinafter, the thermoelectric element 200 will be described in detail with reference to FIG. 2.

Figure 2 shows a thermoelectric device according to an embodiment of the present invention.

2, the thermoelectric element 200 includes a lower substrate and an upper substrate 210, 220, at least one N-type thermoelectric body and a P-type thermoelectric body 250, 260, and at least one lower electrode and an upper electrode ( 230, 240).

The lower substrate and the upper substrates 210 and 220 are for depositing and forming lower and upper electrodes 230 and 240 on the substrate. The lower substrate and the upper substrate 210 and 220 may be, for example, alumina (Al ₂ O ₃ ), but are not limited thereto.

On the substrates of the lower substrate and the upper substrates 210 and 220, lower electrodes and upper electrodes 230 and 240 are patterned to connect the N-type thermoelectric bodies and the P-type thermoelectric bodies 250 and 260 in series, respectively. That is, the upper substrate 220 is coupled to the upper portion of the upper electrode 240, and the lower substrate 210 is coupled to the lower portion of the lower electrode 230. Here, the lower electrode and the upper electrode 230, 240 are nickel (Ni), aluminum (Al), copper (Cu), platinum (Pt), ruthenium (Ru), rhodium (Rh), gold (Au), tungsten ( W), cobalt (Co), palladium (Pd), titanium (Ti), tantalum (Ta), iron (Fe), molybdenum (Mo), hafnium (Hf), lanthanum (La), iridium (Ir), and silver (Ag) may be formed of a metal having excellent conductivity.

The N-type thermoelectric body and the P-type thermoelectric bodies 250 and 260 are coupled between the lower electrode and the upper electrode 230 and 240. Accordingly, the N-type thermoelectric body and the P-type thermoelectric bodies 250 and 260 are serially connected to different polarities by the lower and upper electrodes 230 and 240 patterned on the lower substrate and the upper substrates 210 and 220. . On the other hand, the size and shape of the N-type thermoelectric body and the P-type thermoelectric body 250, 260 vary depending on the pattern of the lower electrode and the upper electrode 230, 240 formed on the lower substrate and the upper substrate 210, 220. Can be designed.

Here, as the thermoelectric material for forming the N-type thermoelectric and P-type thermoelectric (250, 260), bismuth (Bi), antimony (Sb), tellurium (Te), selenium (Se), or a complex of these, telluride Bismuth (Bi2Te), selenide bismuth (Bi2Se4), and the like. As a more detailed example, when the thermoelectric body is N-type, it may be a bismuth-tellurium-based compound (Bi _x Te _{1 -x} ) or a bismuth-tellenium-selenium-based (Bi ₂ Te _3-y Se _y ) compound. In the case of P type, it may be an antimony-tellurium compound (Sb _x Te _1-x ) or a bismuth-antimony-tellurium-based (Bi _y Sb _2-y Te ₃ ) compound.

Here, the thermoelectric element 200 may further include a filling material 270 filled between the lower substrate and the upper substrates 210 and 220. As the filler 270, a polymer-based material having excellent flexibility may be used.

Referring to FIG. 3 showing a flexible thermoelectric element including a filler, when the filler 270 is filled in an empty space between the lower substrate and the upper substrates 210 and 220, the thermoelectric element 200 exhibits flexibility and stretchability. It becomes flexible, and accordingly, the thermoelectric element 200 can be easily attached to the user's face when combined with the mask pack 100.

On the other hand, when the thermal conductivity of the filler 270 is high, the power generation efficiency of the thermoelectric element 200 decreases as the temperature difference between both sides of the thermoelectric element 200 decreases, so a material having low thermal conductivity is used as the filler 270. It is desirable to do. Accordingly, as the filler 270, a material having a thermal conductivity of a predetermined threshold or less may be used depending on the material of the lower and upper electrodes 230 and 240 and the thermoelectric material.

The above-described thermoelectric element 200 may be formed in a form having various patterns according to the patterning of the thermoelectric body and the electrode.

Meanwhile, referring to FIG. 5, the thermoelectric element according to an embodiment may have a thermoelectric body and an electrode patterned according to blood spots on the face. In general, in oriental medicine, acupuncture is performed on the acupuncture points to treat blood circulation disorders and metabolic degradation occurring in the body parts. The acupuncture points of the face in oriental medicine may include, for example, any one or more of Chanjuk, Sun, Dong materials, Jeongmyeong, Seungeup, Cheonggung, Georyo, Influence, Water polo, Seungjang, Jichang, or Cheonyong. However, in the case of blood spots formed on the face, there are many people who refuse to put the needle on the face, so the procedure is not easy.

Accordingly, in the present invention, when the mask pack 100 is attached to the user's face, the lower and upper electrodes 210 and 220 are patterned on the lower substrate and the upper substrates 230 and 240 so as to correspond to each blood spot on the face. By forming, the micro-current generated at each electrode flows into each blood spot on the face, and at the same time, it can efficiently penetrate the skin beauty ingredients, thereby simultaneously exhibiting the skin beauty effect and the therapeutic effect in oriental medicine.

6 illustrates a microcurrent self-generating mask pack according to another embodiment of the present invention.

Referring to FIG. 6, the microcurrent self-generated mask pack according to another embodiment of the present invention is not a type in which the mask pack 100 and the thermoelectric element 200 are integrally combined, but is combined and separated from the mask pack 100.

That is, the thermoelectric element 200 includes at least one protrusion 211 on one side of the lower substrate 210 that is coupled to the outer surface of the mask pack 100 so that it can be coupled and separated from the mask pack 100. After using the mask pack 100, the mask pack 100 may be separated and another mask pack may be combined to provide a reusable form. For reuse, the lower substrate 210 on which the protrusion 211 is formed may be formed of various materials having high electrical conductivity and being washable.

Meanwhile, the lower substrate 210 may be provided in various forms for coupling with the mask pack 100 in addition to the form in which the protrusion 211 is formed as shown. As an example, the lower substrate 210 may further include at least one fixing part (not shown) to be coupled to the mask pack 100 on one side. The fixing part (not shown) may be provided in a form in which one side of the lower substrate 210 is dug by a predetermined depth according to the size and shape of the mask pack 100.

Here, the thermoelectric element 200 may further include a cover (not shown) that seals the lower substrate and the upper substrates 210 and 220. The cover (not shown) may seal the lower substrate and the upper substrates 210 and 220 to wash the thermoelectric element 200 and then reuse it. To this end, the cover (not shown) may be formed of various materials having high electrical conductivity and being washable.

The cover (not shown) has, for example, at least one protrusion formed on one side so as to be combined with the mask pack 100 on one side, as in the form of the lower substrate 210 described above, or the mask pack 100 on one side. It may be provided in various forms, such as a form that includes a fixed portion (not shown) that can be seated.

Meanwhile, in addition to the above-described embodiment, the microcurrent self-generating mask pack according to another embodiment of the present invention may include a form in which the above-described thermoelectric element 200 is coupled between a pair of mask packs. That is, the mask pack 100 is coupled to one side and the other side of the thermoelectric element 200, so that all of the skin beauty ingredients applied to each mask pack 100 can permeate the user's face.

At this time, the thermoelectric element 200 coupled between the pair of mask packs is etched along the patterned thermoelectric body and electrodes other than the lower substrate and the upper substrates 210 and 220, and the combined area when the pair of mask packs are joined to each other It is desirable to make it as wide as possible.

7 to 9 illustrate a method of manufacturing a microcurrent self-generating mask pack according to an embodiment of the present invention. Hereinafter, detailed descriptions of parts overlapping with those described above will be omitted.

In FIG. 7, in the electrode forming step, at least one upper electrode 240 is patterned under the upper substrate 220, and at least one lower electrode 230 is patterned over the lower substrate 210. The lower electrode and the upper electrode 230 and 240 are respectively connected to the lower substrate and the upper substrate 210 and 220 so that at least one N-type thermoelectric and P-type thermoelectric 250 and 260 to be described later are connected in series with different polarities. Patterning is formed. The lower electrode and the upper electrode 230 and 240 are formed by coating various metal layers having excellent conductivity on the substrate.

Meanwhile, prior to the electrode forming step, the sacrificial substrate is further coupled to the lower portion of the lower substrate 210 and the upper portion of the upper substrate 220 by forming the first sacrificial substrate and the second sacrificial substrates 280 and 290, respectively. An electrode forming step may be performed on the lower substrate and the upper substrate 210, 220. The sacrificial substrate is a support that maintains the shape of the thermoelectric element until the thermoelectric element is completed, and various materials having weak adhesive strength with the lower and upper substrates 210 and 220 can be used for easy removal of the sacrificial substrate later. .

Next, the thermoelectric forming step is formed by patterning at least one N-type thermoelectric body and P-type thermoelectric bodies 250 and 260 on an upper portion of the lower substrate 210 on which the electrodes are patterned. The thermoelectric body may be patterned by various methods.

In the screen printing technique, a screen mask having holes formed in a pattern of a certain shape is placed on a substrate, and the paste is sprayed on the screen mask, or pressure is applied to the paste while pushing the paste into the hole of the screen mask so that the paste is the same as the pattern of the mask. It is a technique to be formed on the image.

On the other hand, when the thermoelectric forming step is performed by a screen printing technique, the thermoelectric forming step may include a step of synthesizing a thermoelectric paste, a printing step, and a thermal firing treatment step.

The step of synthesizing the thermoelectric paste synthesizes the thermoelectric pastes of the N-type thermoelectric body and the P-type thermoelectric bodies 250 and 260 for screen printing. In order to form thermoelectric paste in a state in which thermoelectric material powder having a suitable viscosity is uniformly mixed, thermoelectric material powder, a solvent for controlling the fluidity of the paste, binder for adjusting the printing resolution and binder ( Adhesion) can be formed by mixing glass powder. Here, the thermoelectric material powder includes bismuth (Bi), antimony (Sb), tellurium (Te), selenium (Se), or bismuth telluride (Bi2Te), bismuth selenide (Bi2Se4), etc., as described above. It can contain. As a more detailed example, when the thermoelectric body is N-type, it may be a bismuth-tellurium-based compound (Bi _x Te _{1 -x} ) or a bismuth-tellenium-selenium-based (Bi ₂ Te _3-y Se _y ) compound. In the case of P type, it may be an antimony-tellurium compound (Sb _x Te _{1 -x} ) or a bismuth-antimony-tellurium-based (Bi _y Sb _{2 - y} Te ₃ ) compound.

Next, in the printing step, the synthesized thermoelectric paste is printed on the upper portion of the lower substrate 210. Printing may be performed in a state in which a screen mask on which a certain pattern is formed is placed on the lower substrate 210.

In the thermal firing treatment step, the lower substrate 210 on which the thermoelectric paste is printed is thermally fired. The heat firing treatment can be performed at various temperature conditions. Through such a heat treatment step, the N-type thermoelectric body and the P-type thermoelectric bodies 250 and 260 may be coated with a diffusion barrier to block components harmful to the human body.

In FIG. 8, when a thermoelectric body is formed on the lower substrate 210 through the above-described steps, the upper substrate 220 is coupled to the N-type thermoelectric bodies and the P-type thermoelectric bodies 250 and 260.

When the upper substrate 220 is coupled, a step of filling the filling material 270 between the lower substrate and the upper substrates 210 and 220 is performed. The filling may be performed through various techniques capable of filling the empty space between the N-type thermoelectric body and the P-type thermoelectric bodies 250 and 260. On the other hand, the filling material 270 to be filled is preferably a material that is flexible and has low thermal conductivity.

Here, when the first sacrificial substrate and the second sacrificial substrate 280 and 290 are formed on the lower portion of the lower substrate 210 and the upper substrate 220, respectively, the first sacrificial substrate and the second sacrificial substrate ( 280, 290) may be further included.

In FIG. 9, the lower substrate and the upper substrates 210 and 220 are etched along the patterned thermoelectric body and electrodes. Accordingly, a thermoelectric element etched according to a pattern may be provided. Here, the etching may be performed through various physical or chemical polishing techniques.

Finally, when the step of coupling the thermoelectric element 200 formed through FIGS. 7 to 9 to the outer surface of the mask pack 100 is performed, a microcurrent self-generating mask pack according to an embodiment of the present invention is provided.

The generated microcurrent was measured to be 2.4 [μA], and it can be seen that the liquid applied to the mask pack penetrated into the dermal layer according to the generated microcurrent.

Through the present invention as described above, by converting the temperature difference into electrical energy, the microcurrent generated by flowing to the skin helps to regenerate the damaged tissue, and can treat pigmented diseases such as spots, freckles, pigmentation, By increasing the pH balance of the skin, the whitening effect and the antioxidant action of vitamin C can improve skin aging. In addition, there is an advantage that a separate auxiliary power source such as a battery is not required to perform the above-described function.
