Skin care product quality evaluation system based on skin friction performance testing

Abstract

The invention relates to a skin care product quality evaluation system based on skin friction performance testing. The system comprises a friction performance testing device which comprises a testing piece and a sensing system signal processor; the testing piece comprises a friction element and a sensor; the friction element is fixed on an upper PCB of the sensor; a lower PCB of the sensor is fixed on the skin friction performance testing device; the sensor collects the values of positive pressure and friction force and sends the values to the sensing system signal processor; the sensor comprises an X-direction capacitor unit group and a Y-direction capacitor unit group; each of the X-direction capacitor unit group and the Y-direction capacitor unit group comprises capacitor unit modules; and each capacitor unit module is in a comb-tooth-shaped structure comprising more than two strip-shaped capacitor units. According to the skin care product quality evaluation system, the skin friction performance testing device is used for testing the skin on the upper limb of a human body; tested parts comprise the forehead, cheeks, retroauricular parts, and the like on the face; and the testing is flexible and convenient.

Description

technical field [0001] The invention belongs to the field of skin friction performance testing, in particular to a skin care product quality evaluation system based on skin friction performance testing. Background technique [0002] The skin is located on the surface of the human body and is the first line of defense for human health. The realization of many physiological functions of human skin depends on its mechanical properties, and the elastic properties of skin are an important parameter of skin mechanical properties. Therefore, the research on the friction and elastic properties of human skin is of great significance for people to maintain skin health and improve the quality of life. [0003] The skin care products and cosmetics industry is developing rapidly in the global market, and the frictional properties of the skin can be used to quantitatively evaluate skin care products and cosmetics. Skin care products or cosmetics applied on the skin, its function is to r...

Problems solved by technology

[0004] However, most of the current skin testing devices can only test the skin of the upper limbs of the human body, and the testing site is limited. The testing of the forehead, cheeks, behind the ears and other parts of the face is restricted by the machine, and the testing accuracy is limited by the sensor. limited, less sensitive
