Abstract: The present invention relates to the field of medical health monitoring. Disclosed in the present invention is an on-skin sensing system for detecting blood flow status in a postoperative flap and reconstructed limb, the system including a front-end status detection module and a back-end signal processing and outputting module. The front-end status detection module acquires, in real time, blood oxygen saturation and temperature statuses of postoperative flaps and reconstructed limbs. The front-end status detection module uses a flexible packaging layer to package a printed circuit board, and after the surface of the flexible package layer is chemically treated, a pre-polymerized hydrogel solution is injected to carry out cross-linking to obtain a hydrogel adhesive layer, thereby ensuring long-time close attachment to the skin while avoiding bacterial infection on the surface of the skin. The back-end signal processing and outputting module processes blood oxygen saturation and temperature data, and transmits the data to a mobile terminal in real time. The present invention enables on-line monitoring of the blood flow health status of postoperative flaps and reconstructed limbs. When the blood oxygen saturation of the human body is below a normal value or when temperature and pulse signals are abnormal, the mobile terminal will trigger an alarm function, promptly alerting medical staff and the patient.
