The application discloses a MEMS sound wave sensor with scalar and vector composite sensing and a manufacturing method thereof, and belongs to the technical field of micro-electro-mechanical systems. The piezoelectric film, the scalar lower lead wire area and the scalar upper lead wire area constitute a piezoelectric MEMS sensor for sensing scalar sound wave information; the upper plate vector lead wire area, the upper plate, the upper plate lower insulating layer, the upper plate limiting concave frame, the upper plate anti-collision convex point, the back-shaped upper cantilever beam group, the vector lead wire area, the back-shaped lower cantilever beam group, the mass block, the support frame, the lower plate upper insulating layer, the lower plate limiting concave frame, the lower plate anti-collision convex point, the lower plate, the lower plate vector lead wire area constitute a sandwich type differential capacitance MEMS sensor for sensing vector sound wave information. The application has the advantages of scalar and vector composite sensing, small volume, large range, high sensitivity, high reliability, high integration, low cost, low noise, stable performance and the like.

The invention relates to the technical field of cardiac postoperative rehabilitation, in particular to a postoperative rehabilitation device and method for a cardiac pacemaker, and the device comprises a waistband, a limiting cylinder, and a limiting assembly. The limiting assembly comprises a lifting rod, a lifting limiting unit, an angle moving block, an angle retracting and releasing strip and a limiting rod, a patient wears the waistband on the waist, and meanwhile the large left arm is placed in a limiting cylinder; the height of the lifting rod is adjusted through the lifting limiting unit; the angle moving block is transversely pulled, so that the angle winding and unwinding strip is unwound, and the movable range of the limiting cylinder is enlarged; after a proper range is reached, the angle folding and unfolding strip is limited through the limiting rod; therefore, under the condition that the moving range of the arm is limited, the moving action of the arm is reserved as far as possible, after further rehabilitation of the user, the moving range is gradually expanded until the user is completely separated from the limiting cylinder, and compared with a traditional fixing sleeve and a traditional fixing bandage, the rehabilitation effect is remarkably improved.
