Problems solved by technology

[0004] In the portable skin tester currently on the market, the moisture sensor is made of a circuit board made of FR-4 (epoxy resin fiberglass board). The copper foil is directly exposed and in contact with the skin
Although this method can improve the sensitivity of the test, the copper foil in the moisture sensor is prone to oxidation during use and is polluted by cosmetics or skin secretions. Inaccurate results, resulting in measurement bias

Embodiment 1

[0024] figure 1 It is a perspective view of a skin tester according to the embodiment of the present invention. Such as figure 1 As shown, the skin tester includes a main body 200 and a sensing part. The sensing part is arranged on the top of the main body 200. This embodiment does not limit the relative position of the sensing part and the main body 200. The sensing part can also be arranged on the Side portion; the sensing part is provided with a moisture sensor 100, an oil sensor 300, and a processing unit and a transmission unit (not shown) electrically connected to each other are provided in the main body 200, wherein the moisture sensor 100, The oil sensor 300 is electrically connected to the processing unit in the main body 200 , and the moisture sensor 100 is disposed on the periphery of the oil sensor 300 . The transmission unit performs data transmission with the mobile terminal in a wireless manner.

Embodiment 2

[0034] Figure 5 It is the front view of the skin testing instrument of the embodiment of the present invention, from Figure 5 It can be seen from the figure that the difference between the present embodiment and the first embodiment lies in the wiring method of the two wires (111, 112), and the wiring method adopted in the present embodiment is a petal-shaped coupling form. The test principle and equipment used by the instrument are exactly the same as those in Embodiment 1, and will not be repeated here.

[0035] In addition to the arrangements in the above embodiments, the wires can also be in other shapes such as concentric circles, concentric arcs, or even other irregular shapes, as long as the two wires are arranged in parallel and spaced on the flexible circuit board.

[0036]As can be seen from the foregoing embodiments, the present invention provides a skin tester moisture sensor based on a flexible circuit board, which has the following technical effects:

Abstract

The invention provides a skin tester, which comprises a main body (200) and a sensing portion, wherein a moisture sensor is arranged on the sensing portion; the moisture sensor comprises a flexible circuit board (130), a moisture sensing element (110) and a humidity-sensitive thin film (120) which are sequentially arranged from inside to outside; the flexible circuit board is fixed to the main body; the moisture sensing element comprise two lead wires (111, 112) which are arranged on the flexible circuit board at intervals in a parallel mode, and the humidity-sensitive thin film covers the upper side of the moisture sensing element; when a test is conducted, the humidity-sensitive thin film gets into direct contact with skin, the moisture sensing element covering the lower side of the humidity-sensitive thin film is used for measuring a capacitance value of the skin, the moisture sensor is electrically connected to a processing unit in the main body, and a test value, which is converted into a skin moisture content by virtue of the processing unit, is transmitted to a display unit by virtue of a transmission unit. The skin tester disclosed by the invention is simple in structure, high in test accuracy and convenient to use.

Description

technical field [0001] The invention relates to a skin testing instrument, which belongs to the field of human skin testing. Background technique [0002] With the improvement of people's living standards, people's requirements for health are getting higher and higher, and the skin of the human body is responsible for perspiration, sensing the external environment and protecting the human body. An important indicator to reflect the condition of the skin is the moisture content of the skin, because the moisture content of the skin will affect the formation of the mixed film of water and oil on the skin surface. This protective film is very important to prevent skin aging. [0003] The ability of the stratum corneum to retain water can make the water content between 10% and 60%. The water content is determined by internal and external factors. The influence of moisture mixture components, external factors include ambient temperature, humidity, medicines and cosmetics, etc. T...
