Intelligent artificial limb
On January 24, the national military medical center of American Walter Reed is succeeded in installing the new intelligent artificial limb arm by a disability soldier of U.S.A. for the first time . This artificial limb weighs 9 pounds, can be by the intellectual control of human brain, the metal finger can make movements independently, movements are divided into 22 grades meticulously, nearly reach the intensity of mixing the spurious with the genuine.
“Usually, when you want to move the arm, people’s brain will produce the command signal, the signal reaches the arm along nerve conduction, the muscles on the arm are the signal ‘ activate ‘, thus make the movements of moving the arm. After people’s arm is injured and even getting broken, the deformed limb will still receive and keep the order that the brain transmits over. Intelligent artificial limb can collect in the intersection of deformed limb and brain signal that keep in the muscle in real time, the computer command language that can understand of turning it into artificial limb, and then drive the metal arm to produce corresponding sports. This kind of movement made by artificial limb will be more smooth, basically come from instinct and intuition. ” Head of the department of surgery Ball says that the national military medical center of American Walter Reed has a facelift.
This intelligent artificial limb is employed organizations such as material resources test chamber and Walter and Reed national military medical center,etc. to specially set up by the university of Sri Lankan of American John Hopkin, it lasts 4 years to develop it. At present, the scientists of this project are devoted to ” one is tight ” Collect not to be human that brain send out by action command,in order to making movement where arms mechanical make not can ” follow one’s bent ” .
