Abstract
A sensor having a particle barrier is described. In an example, a sensor includes: first and second 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; and a first barrier disposed on the planar support around the first electrode set having a height less than a gap between the planar support and the proof mass to mitigate particle migration into the first or second electrode set.
