Abstract

The application relates to a detection patch, a detection system and a method for detecting physiological substances by using the detection patch. The detection patch comprises a first adhesive patch and a flexible electrode film; the flexible electrode film comprises a flexible substrate and a first electrode group and a second electrode group arranged on the same side of the flexible substrate, and the first electrode group and the second electrode group are used for detecting subcutaneous physiological substances; one side surface of the first adhesive patch is attached to one side surface of the flexible substrate provided with the first electrode group and the second electrode group, and first and second through holes are formed in the first adhesive patch, and the positions of the first electrode group and the second electrode group correspond to the positions of the first and second through holes respectively; and a liquid injection hole is formed in the flexible substrate and communicates with the first and second through holes respectively. The technical scheme can be used for realizing non-invasive detection of subcutaneous physiological substances and reducing detection cost.
