Claim 8:
9. A microelectromechanical systems (MEMS) accelerometer comprising:
a substrate disposed in a plane defined by a first axis and a second axis perpendicular to the first axis;
a first proof mass and a second proof mass coupled to the substrate via an anchor and configured to translate in opposite directions of each other along a third axis perpendicular to the first and second axes;
at least one lever coupling the first proof mass to the second proof mass; and
first and second anchor arms coupled to the anchor and comprising rigid beams extending outwardly from the anchor on opposite sides of the anchor, wherein:
the at least one lever is coupled to the first anchor arm at a midpoint of the at least one lever;
the MEMS accelerometer is configured to detect acceleration along the third axis via detection of translation of the first and second proof masses along the third axis;
the MEMS accelerometer exhibits symmetry about the first and second axes; and
wherein the MEMS accelerometer is further configured to detect acceleration along the first and/or second axes via detection of translation of the first and second proof masses along the first and/or second axes.
