A new type of sensor based on optical fibers offers advantages, including low cost, high sensitivity, and small size. The sensors have already been used to monitor the curvature of structures and robotic arms. But measuring both the magnitude and direction of the spine’s curvature presents an additional challenge — one that the team overcame through innovative design.
