Abstract
Techniques are disclosed for systems and methods to provide concomitant mechanical motion inhibition and electrical distribution for actuator modules, such as microelectromechanical systems (MEMS) based optical actuators adapted to move and/or orient one or more lenses and/or optical devices of a camera module. A mechanical motion inhibition and electrical distribution system may include one or more flexible snubber structures disposed substantially adjacent a MEMS structure and between the MEMS structure and another component of a camera module. Each flexible snubber structure may be implemented with one or more electrical traces, flexible films, snubber films, and/or mechanical stabilizers adapted to route electrical signals to or from the MEMS structure and/or to inhibit mechanical motion of at least a portion of the MEMS structure.
