1. An actuator comprising:
a primary electrode;
a secondary electrode overlapping at least a portion of the primary electrode; and
an electroactive layer disposed between and abutting the primary electrode and the secondary electrode, wherein the primary electrode comprises a plurality of mutually isolated electrically conductive and radially partitioned segments and a mechanical deformation of the electroactive layer is locally controllable over an area of the actuator.
