Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are assigned to the same or similar components throughout the specification.

1 and 4, the patch type sensor module 100 or 200 according to an embodiment of the present invention includes a base substrate 110, a chemical liquid layer 120, sensing units 130 and 230, a controller 140, (150).

The base substrate 110 serves to support the chemical solution layer 120 and the control unit 140 and to function as a circuit board on which at least one antenna 180 and 190 are patterned. Lt; / RTI >

Here, the at least one antenna 180, 190 may include a communication antenna 190 for short-range communication in addition to a wireless power reception antenna 180 for receiving wireless power. This will be described later.

At this time, the base substrate 110 according to the present invention may be formed of a nanofiber web having fine pores so as to ensure flexibility, moisture barrier property and air permeability.

For example, the base substrate 110 may be a nanofiber web on which nanofibers 112 containing a synthetic polymer are accumulated, as shown in FIG. That is, the base substrate 110 may be formed of a nanofiber web having fine pores 114 so that moisture can be blocked while air can pass freely. At this time, the micropores may have an average pore size of 10 μm or less, and the nanofiber web may have a three-dimensional network structure.

Specifically, the base substrate 110 may be a single-layer nanofiber web accumulated so as to have fine pores 114 by electrospinning a spinning solution containing a synthetic polymer and a solvent. Here, the solvent may be water or an alcohol, or may be an organic solvent other than water or alcohol.

In this case, the synthetic polymer may be a fiber-forming polymer capable of electrospinning to realize a nanofiber web through electrospinning without being dissolved by a solvent. Accordingly, even though the base substrate 110 is in contact with the solvent, the base substrate 110 can be attached to the skin for a long period of time by maintaining the nanofiber web shape without being dissolved by the solvent. Even if the base substrate 110 is attached to the skin for a long time, The air can be smoothly introduced into the skin of the user through the fine pores formed in the skin 110, thereby preventing skin troubles such as shedding due to the interruption of the air.

In addition, even if the water-soluble drug solution layer 120 is released in contact with the solvent applied to the skin of the user, the base material 110 is not dissolved by the solvent but remains in the form of nanofiber web, Layer 120 as shown in FIG. Accordingly, the patch-type sensor module 100 or 200 according to the present invention can supply air from the outside to the body part of the user through the fine pores formed in the base substrate 110, The effective component can be effectively absorbed toward the user's body part side.

In addition, the effective ingredient contained in the chemical solution layer 120 can be promoted to penetrate into the skin through the moisture barrier property, and the average pore diameter of the micropore is formed to be 10 탆 or less, It is possible to shield the ultraviolet rays even if no additional functional material such as an ultraviolet shielding component is added by diffusing light.

In addition, since the base substrate 110 is made of a nanofiber web in which nanofibers are accumulated and functions as a circuit board on which the antennas 180 and 190 are patterned, the base substrate 110 can be bent more easily than a polyimide film conventionally used as a material for a flexible circuit board Is excellent, and even when folded or wrinkled, it is excellent in restoration characteristic that it can return to the original flat state.

In addition, since the base substrate 110 is formed of a nanofiber web in which nanofibers are accumulated through electrospinning, the base substrate 110 can be made thinner than conventional flexible circuit boards.

Such a synthetic polymer is not particularly limited as long as it is a resin that can be dissolved in a solvent for electrospinning and can form nanofibers by electrospinning and is not dissolved by a solvent. As a non-limiting example, the synthetic polymer may be selected from the group consisting of polyvinylidene fluoride (PVdF), poly (vinylidene fluoride-co-hexafluoropropylene), perfluoropolymer, polyvinyl chloride, polyvinylidene chloride, Polyoxyethylene-polyoxyethylene-polyoxyethylene-polyoxyethylene-polyoxyethylene-polyoxyethylene-polyoxypropylene oxide copolymers, polyethylene glycol derivatives including polyethylene glycol dialkyl ethers and polyethylene glycol dialkyl esters, Vinyl pyrrolidone-vinyl acetate), polystyrene and polystyrene acrylonitrile copolymers, polyacrylonitrile (PAN), polyacrylonitrile copolymers including polyacrylonitrile methyl methacrylate copolymers, polymethyl methacrylate 0.0 > polymethylmethacrylate < / RTI > copolymer or their Lt; / RTI >

The chemical layer 120 is formed on one surface of the base substrate 110 and provides an effective ingredient which is in direct contact with the skin of the user to benefit the user's skin.

For this, the chemical solution layer 120 may be a nanofiber web formed by mixing a water-soluble polymer, a functional material, and a solvent at an appropriate ratio to prepare a spinning solution, and then spinning the spinning solution to have fine pores.

That is, since the chemical solution layer 120 is formed in the form of a nanofiber web through a spinning solution in which a water-soluble polymer material and a functional material are mixed, the chemical solution layer 120 is attached to the skin side to which the solvent is applied, The functional material may be absorbed by the skin and the water-soluble polymer material may be absorbed by the base material 110.

Here, the water-soluble polymer material is not particularly limited as long as it is a polymer material that is soluble in water or alcohol and can form nanofibers through electrospinning. By way of non-limiting example, the water soluble polymeric material may be selected from the group consisting of polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), polyethylene oxide (PEO), carboxyl methyl cellulose (CMC), starch, polyacrylic acid and hyaluronic acid Hyaluronic acid).

In addition, the functional material may be a dry storage material that is difficult to store in a liquid phase, and the dry storage material may be released to the skin side of the user by releasing it to a liquid or gel state upon dissolution of the water soluble polymer. For example, the dry storage material may be a vitamin, an enzyme, a protein, a peptide-vitamin C derivative, or the like. Usually, the above-mentioned dry storage materials have a property of being decomposed only in the liquid phase. However, it is difficult to store such a dry storage material in a liquid state for a long time.

In the present invention, a dry storage material, which is difficult to store in a liquid state, is included in a spinning liquid together with a water-soluble polymer material and a solvent, and a spinning solution containing the dry storage material is formed into nanofibers through electrospinning, The dry storage material can be restrained in a dry state to the nanofibers constituting the chemical solution layer 120. [

Accordingly, when a water-soluble polymer is dissolved by a solvent, the dry-type functional substance can be released together with the water-soluble polymer and transferred to the skin.

That is, when the patch type sensor module 100 or 200 according to the present invention is attached to the skin, the water-soluble polymer constituting the chemical solution layer 120 is dissolved by the solvent applied to the skin, and the functional substance bound to the water- . Accordingly, the released functional material is absorbed by the skin and the water-soluble polymer dissolved by the solvent can be absorbed by the base substrate 110.

In the present invention, the functional material is a material for skin care and wound healing, and includes ingredients (albutine, niacinamide, ascorbic acid) that help skin whitening, ingredients that help improve skin wrinkles (retinol, adenosine) (EGF), which is a component that helps to prevent skin irritation (titanium dioxide), moisturizing and skin elasticity (snail mucus filtrate, acetylhexapeptide, red ginseng collagen, aquaceramide, regenerating peptide, galactomies fermentation) ), Fibroblast growth factor (FGF) and the like, a protein for healing, an antimicrobial substance such as a silver nanomaterial or chitosan, or the like. In addition, the functional material may be a mixture including at least one selected from water-soluble collagen, vegetable platinum, tocopherol, xylitol and vegetable extract.

At this time, the chemical solution layer 120 may contain a predetermined amount of oil in the spinning solution for forming the chemical solution layer 120 so that the time for melting the chemical solution layer 120 when it is in contact with the solvent can be appropriately adjusted. Accordingly, it is possible to control the overall drying time of the base substrate 110 attached to the skin of the user, so that the drying time suitable for the purpose of use such as sleeping, pack, and protection can be obtained.
