Computer-Controlled Ankle-Foot Prosthesis With Series J-Spring Actuation

An ankle-foot prosthesis comprises a foot structure having a foot keel leaf spring, a heel leaf spring, and an upper J leaf spring above the keel leaf spring. An ankle bearing block is mounted to the keel leaf spring and a shank shell is mounted to the ankle bearing block. A shank interface mounts to the shank shell. A processor controlled active element extends along an axis between the shank shell and the upper leaf-spring.
