[0035] The present invention provides a flexible ion introduction beauty device, such as Figure 1 As shown, it includes a flexible substrate layer 2, a flexible electrode 3 and a porous membrane 1.

[0036] Specifically, the flexible base layer 2 is planar, and a microchannel 4 is configured on one side thereof.

[0037] A pair of flexible electrodes 3 are relatively attached to a side of the flexible base layer 2 away from the microfluidic channel 4, that is, the pair of flexible electrodes 3 and the microfluidic channel 4 are respectively located on opposite sides of the flexible base layer 2. A power source is connected between the pair of flexible electrodes 3. In order to facilitate the connection between the pair of flexible electrodes 3 and the power source, lead wires are provided at the ends of the pair of flexible electrodes 3. In this embodiment, there is no specific restriction on the material of the wire, which can be copper, silver, gold, aluminum, etc.

[0038] The porous membrane 1 is fixed to the side of the flexible base layer 2 provided with the microchannel 4 by bonding. The outer side of the porous membrane 1 is used to be applied to the skin 5, and the skin care products in the microchannel 4 flow into the porous membrane 1 through the electric repulsion of the external electric field, and promote the absorption of the effective ingredients in the skin care products by the skin 5. The flexible ion introduction beauty device of this embodiment has good adhesion to the skin 5, can free the hands, is simple to manufacture, and can greatly save the amount of skin care products.

[0039] According to an embodiment of the present invention, the flexible base layer 2 is made of insulating material, and the flexible base layer 2 includes but is not limited to polydimethylsiloxane.

[0040] According to one embodiment of the present invention, the shape of the microfluidic channel 4 is produced on the flexible substrate layer 2 based on soft lithography technology or laser cutting technology, and the microfluidic channel 4 is obtained based on the flexible material molding method. Specifically, a mold is first made, and then the flexible substrate material is poured in, so as to form the microfluidic channel 4 on the flexible substrate material. The forming method of the microfluidic channel 4 is simple and reliable.

[0041] According to an embodiment of the present invention, the flexible substrate layer includes polydimethylsiloxane or polyethylene terephthalate.

[0042] According to one embodiment of the present invention, the flexible electrode 3 includes a nano-gold electrode, a nano-silver electrode, or metal gallium and its alloy which are liquid at room temperature.

[0043] If the flexible electrode 3 is made of liquid metal gallium and its alloy, it is obtained by injection.

[0044] If the flexible electrode 3 is a nano-gold electrode or a nano-silver electrode, it can be obtained by depositing nano-gold or nano-silver.

[0045] According to one embodiment of the present invention, the flexible electrode 3 is a plate-type electrode, and a pair of the plate-type electrodes are symmetrically distributed on the flexible base layer 2 above the microchannel 4. In order to facilitate the arrangement of a pair of flexible electrodes 3 on the flexible base layer 2, the flexible base layer 2 can be arranged in a structural form with a concave opening, and a pair of flexible electrodes 3 are arranged in the concave opening, which can play a role in stabilizing the flexible electrodes 3.

[0046] According to an embodiment of the present invention, the porous membrane 1 comprises a polydimethylsiloxane porous film or a polycarbonate membrane obtained by adding micron-sized sugar particles and sacrificing sugar. On this basis, the use of other flexible porous membrane 1 materials still falls within the protection scope of the present invention.

[0047] According to one embodiment of the present invention, Figure 2 As shown, the method for preparing the polydimethylsiloxane porous film includes:

[0048] S11: Grind the sugar into micron-sized particles using a ball mill. A Tianchuang small ball mill can be used, and the operation time is 10 minutes or more to obtain sugar containing micron-sized particles;

[0050] S13: mixing the sugar particles obtained in S12, the polydimethylsiloxane curing agent and the polydimethylsiloxane base agent according to a set mass ratio; wherein the sugar particles: polydimethylsiloxane = 1:4;

[0051] S14: After uniform mixing and vacuuming, a mixed film of a desired thickness is produced based on a spinning process; specifically, a 5 μm thick film can be obtained at a spinning speed of 5000 rpm;

[0052] S15: After ultrasonic cleaning for a set time, sugar particles are removed to form the polydimethylsiloxane porous film. Ultrasonic cleaning can be performed in an ultrasonic cleaning machine for more than 30 minutes to wash away sugar particles and obtain the desired polydimethylsiloxane porous film.

[0055] According to one embodiment of the present invention, the microchannel 4 is a non-sealed structure, and the microchannel 4 is formed with an inlet and an outlet. The skin care product containing ion components is injected from the inlet, so that the microchannel 4 is filled with the skin care product, and the excess skin care product flows out from the outlet.
