Abstract:
A microelectromechanical resonant device having a resonant frequency of oscillation corresponding to a desired application, comprising:a base; a movable body coupled to the base for resonant motion relative to the base about a pivot axis, the base having a mass and a geometry; one or more torsional arms extending between the base and the movable body and aligned with the pivot axis that define the pivot axis; and a flexible member extending from the movable body, the flexible member being configured to flex in response to movement of the movable body about the pivot axis, the flexible member being coupled to the movable body at a location offset from the pivot axis, wherein the dimensions and material of the one or more torsional arms, flexible member, the mass and the geometry are selected to produce the resonant frequency corresponding to the application.
