Abstract:
A microelectromechanical system (MEMS) with reduced noise sensitivity, comprising:a substrate; a first element supported from the substrate for movement between first and second positions with respect to an axis relative to the substrate; a first actuator attached to the first element to exert a force thereupon dependent upon a parameter to be measured and urging the element toward the second position; a second element supported from the substrate for movement between the first and second positions with respect to the axis relative to the substrate; and a sensor assembly communicating with the first and second elements to detect movement of the first and second elements and to provide an output subtracting measurement of movement of the first and second elements so as to provide an output with reduced influence from common mode noise acting to move the first and second elements.
