  • Patent number: 4736629
    Abstract: The accelerometer comprises a substrate (52), a metallic movable plate (50), and a mounting system (54) for mounting the movable plate such that it is positioned above the substrate and can rotate about a flexure axis (64) that is above and is substantially parallel to the substrate. The flexure axis divides the sensing element into first (66) and second (68) sections. The total moments of the first and second sections about the flexure axis are different, such that acceleration normal to the substrate tends to rotate the sensing element about the flexure axis. A first electrode (74) is mounted by the substrate adjacent the first section to form a first capacitor (C.sub.A), and a second electrode (76) is mounted by the substrate adjacent the second section to form a second capacitor (C.sub.B).
