Strut torque characterization. The exoskeletal torque measured by a force sensor and motion capture system were compared to the exoskeletal torque predicted by the deflection of the struts. Using reflective markers on the strut enabled a simple, synchronous method for measuring exoskeletal torque without adding substantial mass. The system was calibrated at various amplitudes and frequencies, similar to those experienced during walking. Only a portion of the calibration data are shown in the figure
