Abstract:
1. An apparatus comprising: a movable base structure comprising an outer surface region and an inner surface region; at least one capacitor element, the at least one capacitor element being spatially disposed adjacent to at least one portion of the movable base structure, wherein the at least one capacitor element is spatially disposed between the outer surface region and the inner surface region; at least one central anchor structure spatially disposed within a vicinity of the inner surface region of the movable base structure; at least one peripheral anchor structure spatially disposed within a vicinity of the outer surface region of the movable base structure; and at least one central spring structure, the at least one central spring structure being operably coupled to the at least one peripheral anchor structure and at least one portion of the inner surface region, wherein the at least one central spring structure is proportional to the number of the at least one capacitor element.
