Bimorphically actuated, oscillating micromirror

摘要

The micro-mirror has a movable part (11) with two torsion arms (14) comprising an end (14.1) connected to a fixed part (12) through a bimorph actuation unit (15). The actuation unit has a stack (15.1) packed with arranged or connected layers. The stack has a part (15.3) made up of active material cooperating with a passive flexible structure (15.2), where the material can change volume and/or shape under excitation effect. An independent claim is also included for a method for manufacturing a micro-mirror.
