What is the function of adding mica in the capacitive sensor?
Join mica in a capacitive sensor is designed to increase the sensitivity of capacitance and capacitance sensor is provided.
The capacitance of the capacitor is inversely proportional to the distance between the two conductors, proportional to the area of the conductor, and proportional to the dielectric constant of the isolated material between the two plates. That is
The structure principle of capacitor with insulating material between two conductive materials, when two pieces of conductive materials with positive and negative power supply, two pieces of material respectively took charge of the two, because the distance is very near, so charge each other have a strong appeal, the power to save in Hede two pieces of conductive materials, so called capacitors [].
