Abstract
A sensor for evaluating tissue of a subject is provided. The sensor includes a flexible spine disposable on the subject, a flexible member that includes first and second flexible member portions accommodated within the flexible spine, a light source, a detector and a rigid member. The light source is attached to the first flexible member portion and is configured to emit light toward the tissue. The detector is attached to the second flexible member portion and is configured to receive the light having reflected off the tissue. The rigid member is coupled with the first and second flexible member portions. In response to a curvature of the flexible spine, the rigid member moves the first and second flexible member portions along the flexible spine to adjust a distance between the light source and the detector.
