New prosthetic robotic transfer the touch of a hand to his chest, providing them with sensitivity

At present there are already numerous prosthetic robotic enabling people who have suffered some type of amputation and to grasp objects within their means, a normal life.

The main problem that scientists and physicians working in this type of prosthesis is the inability to transmit sensations to the brain indicating, for example, the force is being applied to an object while it is holding. This prevented the people who possessed these prostheses to know if they were holding a glass by pressing it too lightly or without the use of his eyesight.

However, scientists at a University of Chicago have discovered that transplanted nerves in the chest of an amputated hand allows patients to notice the sensations of her hand on his chest. This discovery could be the first step for prosthetic arms incorporate sensors in the fingers to convey the feelings to the chest and, therefore, at hand ... creating the illusion that the patient's real hand is touching the things.

Most scientists and doctors see great potential in this new prosthetic system to avoid many of the problems faced by people with amputees, including the phantom limbs. Some have even dared to say that could be incorporated not only pressure sensors, but any other ... allowing the brain to make use of that information to create new sensory experiences or new meanings.

Again, the technology is within the limits of science fiction.
