Engineers Develop More Stable, Efficient Prosthetic Foot

Engineers have developed a more stable prosthetic leg — and a better way of designing them — that could make challenging terrain more manageable for people who have lost a lower leg. The cornerstone of the new design is a kind of tripod foot that responds to rough terrain by actively shifting pressure between three different contact points. As important as the foot is, the team also developed a tool for quickly emulating and improving their prototypes.
