Abstract :
Sensitivity of applied grasp force is improved for a myoelectrically controlled prosthetic hand under force control through normal force-derivative feedback. Benchtop experiments and results from 12 human test subjects indicate that normal force-derivative feedback can be used in prosthetic hands to help prevent accidental damage to delicate objects.
