发明名称 CAPACITIVE SENSOR HAVING CYCLIC AND ABSOLUTE ELECTRODE SETS
摘要 A capacitive sensor includes first and second variable capacitor electrode sets, respectively disposed upon a planar support surface and a proof mass that is compliantly displaceable along a first axis substantially parallel to the planar support surface. The first electrode set produces a cyclic variation in capacitance over a range of displacement of the proof mass along the first axis, and the second electrode set produces an absolute capacitance variation throughout the range of displacement along the first axis.
