Abstract
The pressure sensing device includes a substrate and a pressure sensor. The pressure sensor used is a thin-film piezoresistive sensor with a certain area, and a power wire, a ground wire, and two differential wires are led out from ends of the pressure sensor respectively, and the pressure sensor is arranged on the substrate. The substrate is simply attached to the object being tested that is to be subjected to pressure, the pressure sensor is connected to a pressure sensing detection circuit, the object being tested deforms under pressure, and the thin-film piezoresistive sensor deforms as the substrate deforms. The deformation of the substrate is detected through detecting the voltage drop between the two differential wires, which is converted to obtain the pressure on the object being tested, thereby realizing a pressure-sensitive touch function. A pressure sensing method and an electronic terminal with the pressure sensing device are also provided.
