Bionic Leg Allows Amputee To Walk Faster

With support from the National Science Foundation and continued support from the National Institutes of Health, Vanderbilt University mechanical engineer Michael Goldfarb has spent several years developing a state-of-the-art prosthetic leg with powered knee and ankle joint, which operates with special sensors, an electric motor, a battery, and computer technology. Sensors monitor the user's motion and microprocessors figure out what the person is trying to do.
