Abstract:
A micromachined device comprising:a first proof mass and a second proof mass, the first and second proof masses each having a plurality of support arms flexibly coupling the masses to a substrate; and at least one spring element having a first end and a second end, the first end of the at least one spring element connected to the first proof mass and the second end of the at least one spring element connected to the second proof mass, the at least one spring element compressing when the first proof mass and the second proof mass move toward each other, and uncompressing when the first proof mass and the second proof mass move away from each other, wherein the first end of the at least one spring element and the second end of the at least one spring element form a straight line that comprises an axis of oscillation of the first proof mass and the second proof mass.
