Bionic Leg For Amputees
After seven years of hard work, researchers at Vanderbilt University have created a new “bionic” leg that is much more lighter, faster, and smarter than the regular prosthetic leg. It is the only prosthetic leg that has the powered knee and ankle joint operating together.
“A passive leg is always a step behind me. The Vanderbilt leg is only a split-second behind”, says Craig Hutto, who has been testing this leg for several years. The Vanderbilt prosthetic walks 25% faster on level surfaces than other prosthetic legs.
The “bionic” leg has sensors that detect motion of the wearer. This data is then sent to microprocessors that predict what the person is trying to do, and acts accordingly to allows the wearer to operate the leg in ways that will make movement easier.
This leg makes it easy for a person to sit, stand, walk, and go up and down stairs and ramps. It can continuously walk for 13 to 14 kilometers (three days of normal activity) on a single charge, and weighs only nine pounds (human lower legs usually weigh more than that).
Freedom Innovations has been given exclusive rights to develop this prosthesis.

Its mind blowing article. I think this is really new discovery for those who wanna walk alone without any help…..
Conspicuous article, all of this is quite corresponding to a situation that I publicise. Please curb it out sometime and undergo uncommitted to reach me a comenet on it and enjoin me what you think. I'm ever perception for feedback.
