Abstract:
In a microelectromechanical structure having one or more moveable masses, said one or more masses being capable of movement in one or more dimensions, a method for controlling undesired movements of said one or more moveable masses comprising the steps of:providing one or more electrodes near said mass, thereby forming one or more variable capacitances between said electrodes and said one or more moveable masses; measuring the variations in the capacitance of said one or more variable capacitances due to movement of said one or more masses; imposing a voltage on one or more of said electrodes, thereby creating an electrostatic force between said one or more electrodes and said one or more moveable masses; and varying the magnitude of said voltage on said electrodes as a function of said measured variations in said capacitance of said one or more capacitive interfaces.
