Actuating a human hand prosthesis: model study

The researchers all over the world give a lot of attention to modeling the human hand in order to obtain good hand prosthesis. Despite many attempts, very few solutions are available on the market, and even those are far too expensive to reach for most of the patients. Knowing that it is very important to have a model as close as possible to the natural one, we determined the kinematical and dynamical models of the human hand. We realized, also, that if we limit our model's capabilities to the most important function of the hand, namely prehension, considering that the vast majority of potential patients have one good hand for delicate actions, then we can much quickly obtain an affordable human hand prosthesis with grabbing capabilities, to help impaired people to manage through most of the daily activities.
