Abstract
Some embodiments may include a multi-layer flexure that may be used in an optical image stabilization voice coil motor (OIS VCM) actuator of a camera. The multi-layer flexure module may include a dynamic platform and a static platform along with multiple layers of flexure arms that mechanically connect the dynamic platform to the static platform. In some examples, the multi-layer flexure may include electrical traces configured to convey signals from the dynamic platform to the static platform. The electrical traces may be routed from the dynamic platform to the static platform via the flexure arms. In some embodiments, a multi-layer flexure may have a greater stiffness in a Z-direction aligning with an optical axis of a camera and may have a lower stiffness in X and Y directions corresponding to optical image stabilization directions of an OIS VCM actuator.
