Single-walled carbon nanotube-based flexible electrode array, wearable sensor and in-situ sweat monitoring method thereof

The invention discloses a single-walled carbon nanotube-based flexible electrode array, an intelligent wearable sensor and an application of the intelligent wearable sensor in in-situ sweat analysis. According to the method, a high-dispersity SWCNTs solution is used as a raw material, an SWCNTs conducting layer is selectively deposited in an electrode array area of a template filter membrane in a vacuum filtration mode, and then a high-precision SWCNTs-based flexible electrode array can be rapidly prepared in batches through PDMS transfer printing; after the flexible electrode array is subsequently functionalized, the flexible electrode array is further integrated with a signal acquisition and processing circuit system, a processed sensing signal is transmitted to a display module (such as a mobile phone APP), namely, the acquisition quantity is intelligently read, the concentration of various target objects is presented in real time, and the intelligent electrochemical in-situ monitoring system has a wide ap
