  • Variable-area comb capacitor-based MEMS relative gravimeter probe and gravimeter
    Patent number: 11906693
    Abstract: A gravimeter probe includes a spring structure, a proof mass, movable comb fingers, fixed comb fingers, and an outer frame. A fixed end of the spring structure is arranged on the outer frame and a free end thereof is connected to the proof mass. The movable comb fingers are arranged on upper and lower surfaces of the proof mass, and the fixed comb fingers are correspondingly arranged on the outer frame. Each of the movable comb fingers and the fixed comb fingers has a special-shaped comb finger structure. The special-shaped comb finger structure includes a comb finger bottom portion and a comb finger top portion, and the width of the comb finger bottom portion is smaller than the width of the comb finger top portion.
