Claim 10:
11. An electronic terminal, comprising an object being tested, a pressure sensor, and a pressure sensing detection circuit;
wherein the pressure sensor comprises:
an upper substrate attached to the object being tested and a force transmission structure connected to the upper substrate, the force transmission structure comprises 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 is 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;

wherein the pressure sensing detection circuit is electrically connected to the strain sensing resistor.
