Born in Dean Kamen's DEKA Research and Development institution, this prosthetic arm received approval from the Food and Drug Administration earlier this month. Instead of the hook device amputees have been using for years, the DEKA Arm can perform several movements at once, using electrical signals from muscle contractions in the area where the prosthetic is attached.
Dubbed the Luke (after Luke Skywalker, who got his own prosthetic hand in "The Empire Strikes Back"), the arm, which is not yet available, will allow amputees to raise their arms above their head and perform more complex tasks than they can today.
