Abstract
An example housing that protects a ceramic actuator from excessive and damaging displacement comprises a protective structure arranged to limit the motion of the actuator by contacting at least one section of the actuator between fixed and moving terminals of said actuator. A suspension system for a lens holder of a miniature camera actuated by a ceramic actuator comprises four pivotally connected link elements in form of a parallelogram connected between a housing and the lens holder.
