1. An apparatus for force sensing, located in an electronic device, wherein the electronic device comprises a deformable portion, and the apparatus comprises:
at least one first sensor, configured to generate a first signal, wherein the first signal is determined by deformation of the deformable portion and temperature at the deformable portion;
at least one second sensor, configured to generate a second signal, wherein the second signal is determined by the temperature at the deformable portion; and
a comparator, configured to:
receive the first signal and the second signal;
determine whether the deformable portion deforms, based on the first signal, the second signal, and a threshold signal, wherein the threshold signal corresponds to a degree of the deformation; and
generate a third signal, wherein the third signal is in an active state in response to determining that the deformable portion deforms.
