To address some of these issues, engineers at Vanderbilt University have been spending the past 7 years working on a “bionic” above knee prosthesis that has a powered knee and ankle and a microprocessor to coordinate their function. The ultra-light powered device lets amputees walk 25% faster, and uses 30-40% less energy than traditional devices. It is also designed to make sitting, standing, and going up/down stairs and ramps much easier. The device weighs approximately 9 pounds and operates for 3 days on a single battery charge. The prosthetic even incorporates an “anti-stumble” feature which will assist the amputee in regaining balance if it senses the user is about to fall.
