Abstract
A pressure sensor is formed by sandwiching a pressure-sensitive dielectric membrane between and in contact with a pair of electrodes. As pressure is applied, the dielectric constant of the pressure-sensitive membrane changes while the distance of separation between the pair of electrodes remains constant. This change in the dielectric constant is detected by a circuit as a change in the electrostatic capacitance between the electrodes to measure the applied pressure. Since the pressure-sensitive dielectric membrane is not required to undergo any elastic deformation for measuring the pressure, the pressure sensor can be made extremely thin.
