Biomimetic Slope Adaptive Foot-Ankle Prosthesis This project will develop an innovative mechanical/hydraulic foot-ankle system that will help lower extremity prosthesis wearers to walk or run in a wider range of environments with close to normal walking biomechanics. The proposed system will have a unique combination of features, all mechanically implemented without electronics or external power: The foot/ankle alignment will adapt the end of ankle motion (i.e., the dorsiflexion stop) to sloped walking surfaces on every step of walking and without delays. A near-normal range of hydraulic ankle motion improves comfort and stability, providing customization of plantar and dorsiflexion resistance. Utilizing well-proven carbon fiber footplates, the foot will provide near-normal energy storage and return during walking. The split-toe feature provides multi-axial compliance, for stability and comfort on non-level ground. A unique toe-lift spring ensures toe clearance during swing phase, for stability and safety. With an integrated and robust design, the foot-ankle system that results from Phase 2 and 3 can be highly water and dirt resistant, allowing use in a very wide range of environments compared with most available feet.
