Skin biochemical index detection method and system based on biological dielectric spectrum

Abstract

The invention discloses a skin biochemical index detection method and system based on biological dielectric spectrum. The method includes covering a detected target by pasting an excitation electrode and a measurement electrode, exciting the target through the excitation electrode, and collecting signals of the measurement electrode; performing denoising pretreatment of the collected signals, and drawing dielectric spectrum; fitting variables, namely parameters to be measured, and parameters of the dielectric spectrum, and calculating weight factors of the parameters to be measured; performing model matching analysis of the calculated weight factors, and acquiring and outputting the weight factors exceeding the critical value of the model function and corresponded parameters. The skin biochemical index detection can be implemented by detecting target dielectric properties, the biochemical indexes of different skins can be detected in real time, use of multiple sensors is omitted, the size of the product is reduced greatly, and the product integration and application field expansion are benefited.

Description

technical field [0001] The invention relates to the detection field, in particular to a method and system for detecting skin biochemical indicators based on biodielectric spectrum. Background technique [0002] The skin is an important protective barrier of the human body. In daily life, due to the joint action of the internal metabolism of the body and the external environment, various physiological and biochemical indicators of the skin are changing. Studies have proved that the content of various important elements in the skin will be maintained in a relatively stable state. If abnormal indicators appear, a series of normal physiological activities of cells will be affected, resulting in metabolic disorders in the human body. In addition, if the skin receives physical and biochemical damage from the external environment, resulting in skin damage, it will also cause a variety of diseases in the human body. Therefore, wearable dynamic monitoring of skin biochemical indicat...
