Pressure signature of forearm as predictor of grip force
Michael Wininger, BS, et al.
Many U.S. military veterans have lost their upper limbs and rely on a prosthesis for hand function. Restoration of function is limited, however, since available prostheses offer insufficient control of applied force. While robotic technology has produced hands that move with dexterity in many degrees of freedom, controlling them is currently beyond the reach of human amputees. Despite steady advances in basic prosthetic functioning through improved processing of multiple myoelectric signals, human control remains the biggest challenge to restoring dexterity. We present a new method of control that may endow upper-limb prostheses with more dexterity and proportional control of force.
