Abstract

The invention discloses a pressure-sensitive film, a preparation method of the pressure-sensitive film and a pressure sensor. The preparation method of the pressure-sensitive film comprises the stepsof preparing a first solution comprising one-dimensional or two-dimensional metal nanoparticles; preparing a second solution comprising a polymer compatible with the metal nanoparticles; mixing the first solution with the second solution to remove moisture from the mixed solution, so as to obtain the pressure-sensitive film. Before the first solution is mixed with the second solution, a plastic agent is added into the second solution. According to the preparation method of the pressure-sensitive film, the pressure-sensitive film sensitive to pressure and capable of absorbing spectrum can be prepared. The pressure-sensitive film can be used in a pressure sensor, and the electromagnetic interference resistance of the sensor is improved.

Description

technical field [0001] The invention relates to the field of physical quantity detection, in particular to a pressure-sensitive film, a method for making the pressure-sensitive film and a pressure sensor. Background technique [0002] Most of the existing pressure sensors use the principle of electromagnetic induction to realize pressure detection. During the use of the sensor, due to the interference of the surrounding electromagnetic equipment or the machine in the application, the electromagnetic signal of the sensor usually fails, resulting in inaccurate pressure detection. The problem. [0003] Therefore, there is an urgent need for a pressure sensing material and device with stronger anti-interference ability. Contents of the invention [0004] In view of this, the object of the present invention is to provide a pressure-sensitive film whose absorption spectrum is sensitive to pressure and its manufacturing method. The object of the present invention is also to prov...
