Robotic arm allows amputee to touch and feel again - using only the power of THOUGHT

A robotic arm allows amputees to touch and feel objects again by using the power of thought to control it. The high-tech prosthetic, developed by the University of Utah, uses microwires implanted under the skin, which send signals to an external computer that tells the arm to move. The arm even has sensors that transmit signals to the microwires, mimicking the feeling of the hand when it grabs something. This allows users to'feel' objects being held so the brain knows not to cause the prosthetic hand too squeeze too tightly. Fascinating video shows real estate agent Keven Walgamott, who lost his hand and part of his arm in an accident, able to pluck grapes and hold eggs without crushing them - and even put on his wedding ring.
