Abstract
The present application discloses a strain sensing film, a pressure sensor, and a strain sensing system; the strain sensing film includes a semiconductor film, and by arranging a temperature sensor in the semiconductor film, the sensitivity of the strain sensing film is adjusted according to an effective gauge factor obtained from a calibration test and a correlation table reflecting a correlation between an effective gauge factor and a temperature, a better effective gauge factor compensation is achieved, a high sensitivity of the strain gauge of the semiconductor film can be fully utilized. The strain sensing film can be widely used in application scenarios that need to measure local strain or strain variation, force or force variation, pressure or pressure change, displacement, deformation, bending, or bending deformation.
