A highly dexterous, bio-inspired artificial hand and sensory system that could provide patients with active feeling, is being developed by a European project called cyberhand.

The main objectives of the CYBERHAND Project are to increase the basic knowledge of neural
regeneration, and sensory-motor control of the hand in humans and to exploit this knowledge to
develop a new kind of hand prosthesis which will overcome some of the drawbacks of current
systems. This new prosthesis will:

1.) be felt by an amputee as the lost natural limb delivering her/him a natural sensory feedback by
means of the stimulation of some specific afferent nerves;

2.) be controlled in a very natural way by processing the efferent neural signals coming from the
central nervous system (reducing the discomfort of the current EMG-based control prosthesis).
