▎ 摘　　要

NOVELTY - The sensor has a first sensing layer and a second sensing layer. The first sensing layer includes a first substrate layer (11), and a first elastic wire (12) and a sensing unit (13) which are placed on the first substrate layer. The sensing unit includes multi-level cones with different heights, and the cones are made of resistive materials. The second sensing layer includes a second substrate layer (21), and a second elastic wire (22) which is placed on the second substrate layer. The conductive material includes one of carbon nano tube, conductive carbon black, graphene, nano silver wire, liquid metal, poly 3, 4-ethylene dioxythiophene/polystyrene sulfonate and MXene. USE - High-sensitivity large-range resistance-type pressure sensor for use in wearable device, robot and virtual reality man-machine interaction field. ADVANTAGE - The high-sensitivity large-range resistance-type pressure sensor solves the technical problem of bad commonality of the resistance pressure sensor in the existing technology and effectively improves the commonality. By setting multiple layers of conical bodies with different heights, the sensitivity of the pressure sensor can be improved in each range range. As the pressure of the sensor is increased, the deformation of the conical body with smaller height is gradually triggered, compared with the deformed of the bottom of the body with higher height. The deformation at the upper portion of the tip at the small height is caused by the larger resistance change, so it can be graded by the higher detection sensitivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of a high-sensitivity large-range resistor-type pressure sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the high-sensitivity large-range resistance type pressure sensor. 11First substrate layer 12First elastic wire 13Sensing unit 21Second substrate layer 22Second elastic wire
