An in-fiber Bragg grating sensor for contact force and stress measurements in articular joints
Contact forces were applied by compressing a calibrated
spring with a manual screw-follower (not shown). Bragg wavelength shifts
were measured using an optical spectrum analyzer (ANDO AQ6331 , Tokyo, Japan) as described below.
