Now MIT engineers have developed a simple, low-cost, passive prosthetic foot that they can tailor to an individual. Given a user?s body weight and size, the researchers can tune the shape and stiffness of the prosthetic foot, such that the user?s walk is similar to an able-bodied gait. They estimate that the foot, if manufactured on a wide scale, could cost an order of magnitude less than existing products.This model is potentially game-changing for the industry, because we can fully quantify the foot and tune it for individuals, and use cheaper materials.
