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 plurality of layers stacked in a direction orthogonal to an image plane defined by the image sensor, the plurality of layers comprising:
a conductive layer comprising a signal pad region and a signal trace region, and
a conductive ground layer, wherein a distance between at least one section of the signal pad region and the conductive ground layer is greater than a distance between at least a section of the signal trace region and the conductive ground layer.
