[0002] At present, there are many skin-contact electronic devices on the market, including: skin electrodes, smart watches (monitoring heartbeat) or wearable sweat analyzers. Electricity, ECG, etc., but lack the measurement of various chemical substances contained in human sweat (such as blood sugar, electrolytes, lactic acid, etc.); among them, a small number of existing wearable devices that measure sweat are all based on electrical Measurements based on chemical principles without effective use of the optical properties of various liquids

[0003] Among them, the existing skin-contact electronic devices have certain shortcomings or deficiencies: the analysis based on electrochemical principles requires energy consumption, and a large amount of electric energy is required to achieve long-term in vivo measurement; and the key reaction reagents required for various electrochemical analyzes ( For example, the redox catalyst required for blood sugar analysis) is greatly affected by ambient temperature, body surface pH, etc., which is not suitable for long-term stable measurement and needs to be replaced frequently; in addition, existing skin-contact electronic devices are often limited by energy and wireless communication Demand, the overall size is large, it cannot be stably applied on the skin surface for a long time, and it needs auxiliary means such as wrist straps to fix it, which can easily lead to human skin allergies and other phenomena
