Method for design and manufacture of compliant prosthetic foot

A compliant prosthetic foot is designed and fabricated by combining a compliant mechanism optimization technique with a calculation of low leg trajectory error under a reference loading condition. The compliant mechanism optimization technique includes a set of determinants for the compliant prosthetic foot. An optimized set of determinants of the compliant prosthetic foot is formed that minimizes the lower leg trajectory error relative to a target kinematic data set. The compliant prosthetic foot is then fabricated in conformance with the optimized set of determinants.

A system for sizing and fitting an individual for apparel, accessories, or prosthetics includes at least one energy emitter configured to emit energy onto a field-of-view that contains an individual, and at least one energy sensor configured to capture reflected energy from within the field-of-view. A spatial measurement module calculates spatial measurements of a surface portion of the body of the individual when the individual is either stationary or moving about in real-time, based on data from the energy sensor.

3D Printed Prosthetic Socket For Residual Limb

The invention is a 3D printed prosthetic socket for a residual limb consisting of a 3D printed shell. The 3D printed prosthetic socket comprises a distal end adapted for linking the interconnecting adapter of the socket and a proximal end with an opening adapted for inserting the limb. The 3D printed shell comprises a first housing of the socket comprising an inner wall and an outer wall, wherein the first housing of the socket comprises a rigid region having, in the direction perpendicular to the inner wall, the rigidity of the rigid region and an elastic region having, in the direction perpendicular to the inner wall the rigidity of the elastic region. The rigidity of the elastic region is smaller than the rigidity of the rigid region, wherein the elastic region comprises a set of shaped openings and is adapted for softening the contact of the residual lower limb with the prosthetic socket, wherein the 3D printed shell is made of a single 3D printed part.
