1. A sensor for evaluating tissue of a subject and comprising:
a flexible spine disposable on the subject;
a flexible member comprising first and second flexible member portions accommodated within the flexible spine;
a light source and a detector attached to the first and second flexible member portions, respectively, the light source being configured to emit light toward the tissue and the detector being configured to receive the light having reflected off the tissue; and
a rigid member coupled with the first and second flexible member portions, wherein, in response to a change in curvature of the flexible spine, the rigid member moves the first and second flexible member portions relative to the flexible spine to adjust a distance between the light source and the detector.
