Claim:
1. A pressure sensor calibration system comprising: a first pressure sensor comprising a first plurality of electrodes and a first membrane configured to generate a displacement from a first position to a second position as a function of an electrostatic force; a measuring component configured to determine measurements of sets of capacitance values corresponding to sets of applied voltages at the first plurality of electrodes and by the displacement of the first membrane as the function of the electrostatic force; and a calibration component configured to calibrate the first pressure sensor to a set of target values with a set of sensor parameters derived from the measurements of the sets of capacitance values and a first pressure; wherein the first plurality of electrodes comprise electrodes bridging at least one other pressure sensor comprising different parameters of operation for the displacement by the first pressure or the electrostatic force.
