Abstract
A suspended micromachined structure including a proof mass and multiple support arms configured to suspend the mass above a substrate. At least one support arm may include two spring elements, each attached to the substrate as well as to a rigid lateral element. Thus, there may be three points of attachment along each lateral element. These points of attachment create three effective flexure points along each rigid lateral element that allow the proof mass to move with a great deal of freedom axially, parallel to the substrate. The linearity of the spring constant that acts on the proof mass may be improved.
