Abstract
An improved MEMS transducer apparatus and method is provided. The apparatus has a movable base structure including an outer surface region and at least one portion removed to form at least one inner surface region. At least one intermediate anchor structure is disposed within the inner surface region. The apparatus includes an intermediate spring structure operably coupled to the central anchor structure, and at least one portion of the inner surface region. A capacitor element is disposed within the inner surface region.
