British scientists have developed an
artificial hand that is as deft at handling objects as a real one. Homer
Rahnejat and Russel Speight of the
Bradford University in northern
England, in association with Medi
Mehdian of the Greenwich University, London, have constructed a
prototype hand that has 16 degrees
of freedom, enabling it to move as
well as a human hand.
Says Rahnejat, "We hope to design a neuro-synthesiser that can convey signals to the artificial hand in a form it can interpret mechanically, so that the wearer of the hand has only to think of the action he wants to perform."
