Abstract:
1. A Micro-Electro-Mechanical System (MEMS) comprising: a housing defining an enclosed cavity; one or more stator tines extending from the housing into the cavity; and a MEMS device located in the cavity, the MEMS device comprising: wherein the stator tines include at least one tine with two electrically separated portions, wherein the rotor tines include at least one tine having first and second portions physically separated by a third portion, thereby forming a MEMS sensor having reduced vibration rectification error due to force applied between the rotor tines and the stator tines being less dependent upon position of the rotor tines relative to the stator tines, wherein the electrically separated portions are separated by an oxide layer, wherein when the proof mass is at rest the third portion is level with the oxide layer.
