▎ 摘　　要

NOVELTY - The sensor has a box body composed of a cover plate (13) and a bottom box (12). An inner side of the bottom of box body is provided with a sensing film. The sensing film is utilized for sensing deformation. A center of an upper end of the sensing film are provided with deformation rods (6). An upper side of each deformation rod is connected with two levers. The lever is used for amplifying a bottom edge deformation caused by pressure. A cover plate end of a lower side and a right end of an inner portion of the bottom box are connected with a first graphene (1) and a second graphene (2). Outer ends of the two graphene components are connected with the two lever. The two graphene are utilized for taking a difference value of resistance change amount under tension stress as an output signal to realize secondary increase of sensitivity. USE - Sensitization-type graphene pressure sensor for use in industrial self-control environment. ADVANTAGE - The sensitivity and precision of the sensitization type graphene pressure sensor is improved. The sensitivity error generated when measuring as much as possible is reduced, to ensure the precision of measuring value. The service life of the pressure measuring device is prolonged. The durability of the device is improved, and the toughness is enough, when enough pressure is applied to the device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a control method for implementing the sensitization-type graphene pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of sensitization-type graphene pressure sensor in industrial self-control environment. 1First graphene 2Second graphene 3Left lever 4Right lever 5Spring 6Deformation rod 7Sensing membrane 8First lead 9Second lead 10Connecting plate 11Fixing rod 12Bottom box 13Cover plate
