ABSTRACT:
An apparatus for detecting a static field includes a microelectromechanical systems (MEMS) device having two cantilevered beams of conductive material that are adjacent and substantially parallel to each other. The two beams repel each other in the presence of a static field. At least one sensor detects a respective amount of displacement of the two cantilevered beams from a rest position and determines an amount of repulsion of the two cantilevered beams from each other.
