1. A pressure sensor, comprising:
an upper substrate attached to an object being tested and a force transmission structure connected to the upper substrate, the force transmission structure comprising a first elastomer and a second elastomer arranged alternately in sequence, wherein the first elastomer and second elastomer are abutted against each other, and rigidity of the second elastomer is lower than rigidity of the first elastomer; and
a pressure measuring circuit provided with at least two resistors, at least one of the resistors provided at a position of the upper substrate corresponding to the second elastomer, and the at least one of the resistors is a strain sensing resistor configured to detect deformation of the second elastomer.
