Thick film sensitive component

The utility model belongs to the technical field of pre-tightening force detection, and relates to a thick film sensitive component which comprises an elastic substrate, a plurality of thick film sensitive grids, a plurality of temperature compensation resistors and a protective layer, the elastic substrate is fixedly connected to a preset position of a front-end monitoring node, the plurality of thick film sensitive grids are fixedly connected to one surface of the elastic substrate, and the plurality of temperature compensation resistors are fixedly connected to the other surface of the elastic substrate. The temperature compensation resistors are fixedly connected to the face, connected with the thick film sensitive grids, of the elastic substrate, the multiple thick film sensitive grids are electrically connected with one another to form a Wheatstone bridge, the multiple temperature compensation resistors are electrically connected to bridge arms of the multiple thick film sensitive grids, and the protect
