BIONIC ARM

 Even with today most advanced prosthetic limb , amputees still struggle to perform certain basic task. but the bionic arm made by DEKA, the r&d firm founded by inventor DEAN KAMEN, is nearly as dexterous as the real thing. The luke arm is the first prosthesis that allows a person to make multiple movements, such as rotating the wrist and opening the hand at  once                                         Ten minutes after putting it on , people are able to pick things up, in the clinical trial 90 percent of the 36 participants were able to do previously impossible task , such as unlocking a  door or using chopsticks                                                                                                                                                    Electrode on the skin near the attachments site pick up the electrical impulses signaling muscle contraction and send them to a computer in the prosthesis. The processor translates these message into motion of the integrated elbow, wrist, and hand. user coordinate complex movements with a joystick like sensor on their shoe.                                                                                        by                                                                                                                                             hari suppreethee.shree
