A wearable flexible sensor device that includes a mounting ring, dividers, mounting baseband and adjustment components, the mounting ring having a ring-like structure, with a cavity inside and a first pass on the inner peripheral surface of the mounting ring. Holes are provided, a plurality of first through holes are provided around the central axis of the mounting ring, the partition member has a ring-shaped structure, the partition member is provided with a second through hole, and the partition member is , Provided on the inner wall of the mounting ring, a plurality of sets of adjusting components are provided around the central axis of the mounting ring, the adjusting components include a guide rod, a connecting member and an elastic member, and the guide rod is a second. It penetrates the through hole and is slidably contacted with the partition member, and both side surfaces of the connecting member along the radial direction of the mounting ring are connected to the mounting baseband and the guide rod, respectively, and the elastic member is the diameter of the mounting ring. Provided along the direction, one end is connected to the partition member and the other end is connected to the connecting member. The present invention can protect the flexible sensor and allow the flexible sensor mounted on the mounting baseband to fit on arms of various sizes, ensuring comfortable wearing by the user and accuracy of sensor monitoring. Was done. [Selection diagram] Fig. 1
