1. A camera, comprising:
a lens group;
an image sensor;
an actuator to move the image sensor relative to the lens group; and
a flexure that suspends the image sensor from a stationary structure of the camera and that allows motion of the image sensor enabled by the actuator, the flexure comprising:
a dynamic platform to which the image sensor and a substrate are connected such that the image sensor and the substrate move together with the dynamic platform, wherein a driver associated with the actuator is mounted to the substrate,
a static platform connected to a static portion of the camera,
a plurality of flexure arms that mechanically connect the dynamic platform to the static platform,
a routing layer and a base layer both at least partially forming the dynamic platform, the static platform, and the plurality of flexure arms, and
at least one segmentation region extending through the base layer and configured to physically isolate a return current from the driver and through the base layer from a return current from the image sensor and through the base layer.
