Improved Grasp Force Sensitivity for Prosthetic Hands Through Force-Derivative Feedback

IEEE Trans Biomed Eng. 2008 Feb;55(2 Pt 2):817-21. doi: 10.1109/TBME.2007.912675.


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.
