Abstract
Disclosed is a method for preparing a capacitive pressure sensor. Firstly, two capacitive plates are installed on a dielectric medium; then the dielectric medium and the capacitive plates are coated with an insulating material; then a surface layer of the insulating material is covered with an adhesive; then the dielectric medium and the capacitive plates, which are coated with the adhesive, are pressured into an elastic body; and at last, a plurality of capacitors connected in parallel are pressured into the elastic body for packaging. The method for preparing the capacitive pressure sensor is simple in a preparation process and the obtained capacitive pressure sensor is small in size, simple in structure and precise and reliable in measurement.
