Feel artificial hand

Scientists have successfully created prosthetic devices that allow the mucosal hand to feel like grip.

Experts from Italy, Switzerland and Germany say the prosthetic arm is designed with artificial sensors to detect and evaluate information related to the feeling or grip of the patient.

Left-handed man named Dennis Aabo Sorensen, 36, in Denmark, became the first man to be tested for prosthesis. He lost his left arm part in a fireworks accident in early 2004.

During surgery in Rome, Sorensen implanted four electrodes into the nerve in the arm. These electrodes are connected to artificial sensors in the fingers of the prosthetic arm, which respond to sensory information to the brain and allow the patient to feel the touch, touch or hold of the object.

After the surgery, the patient undergoes a sensory test with a prosthetic arm for one month. Thanks to this arm, he was able to perceive objects of square, round, or soft shapes, the BBC said.

"The biggest difference is that when I hold onto something, I can feel that I'm doing it without looking, I can use my hand in the dark , " Sorensen said.

Professor Silvestro Micera, a member of the research team, said it was the first time a hand-held person could feel the touch and grip of a fake device.
