Abstract
A micro-actuator including a skeleton having flexible beams, a rotor portion, a stator portion, and a damping material. The flexible beams connect the rotor portion to the stator portion and the damping material is applied to the skeleton. The damping material provides a protective layer to the flexible beams of a micro-actuator. The damping material increases the damping characteristics of the micro actuator and limits the penetration of humidity into the skeleton of the micro actuator.
