Piezoresistor with sheet structure

The utility model relates to the technical field of piezoresistors, in particular to a piezoresistor with a sheet structure, which comprises a resistor body, an insulating seat and two second pins, the resistor body is provided with two first pins, two copper pipes arranged in parallel are embedded in the insulating seat, two ends of each copper pipe are provided with plugging holes, and the plugging holes are communicated with the insulating seat. The first pin and the second pin are respectively inserted into the insertion holes at the two ends of the copper pipe to form an electric connection relation, conductive sleeves made of conductive rubber materials are arranged in the insertion holes, and when the first pin or the second pin is inserted into the copper pipe, the conductive sleeves are clamped between the first pin and the copper pipe or between the second pin and the copper pipe. According to the utility model, through the arrangement of the conductive sleeve, when the first pin or the second pin i
