A mechanical interface connecting a biological body segment, such as a limb, portion of a limb or other body segment, to a wearable device such as a prosthetic, orthotic or exoskeletal device, is fabricated by quantitatively mapping a characterized representation of the body segment to form a digital representation of the mechanical interface shape and mechanical interface impedance. The mechanical interface includes a continuous socket defining a contoured inside surface and a contoured outside surface, and includes a material having an intrinsic impedance that varies through the material, so that the intrinsic impedance varies along the contoured inside surface.

The present invention is directed generally to (1) an articulating junction, and articulation method thereof, wherein articulation is facilitated by a plurality of magnetic particles; (2) an articulating junction, and articulation method thereof, wherein the stability and fluidity of the junction is based, at least in part, on the magnetic field(s) of the plurality of magnetic particles; and (3) reducing the resistance to articulation and/or increasing the structural integrity and support, of the articulating junction, via electro-magnetism. Further, the present invention is directed generally to the synergistic combination of magnetic particles and preferred bio-implant-materials and additive-manufacturing methods along with Baker correlation codes. Further, the present invention is directed to an artificial joint for implantation into a living body and methods for constructing such an artificial joint.

A method for producing a prosthesis socket in which a 3D-dataset is produced of an outer contour of a stump on which a prosthesis socket is to be mounted, and a base socket is produced from a first material in a 3D printing method using said 3D dataset, wherein an inner contour of the base socket corresponds to the outer contour of the stump, and at least one stabilising element consisting of a second material is laminated onto the base socket.

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.

In one embodiment, a system or method for kinematically synchronizing uncoupled, dissimilar rotational systems pertain to modeling a first rotational system using an equation of motion to obtain a first system model, modeling a second rotational system that is physically dissimilar to the first rotational system using the equation of motion to obtain a second system model, and matching kinematic matching coefficients of the equations of motion for the first and second system models.

A method of designing and manufacturing an elastic circumferential rim of a prosthetic or orthotic device includes a step of creating a basic structure of the elastic circumferential rim based on the type of the prosthetic or orthotic device. Requirements are determined for stiffness of the elastic circumferential rim in the individual areas along the circumference of the elastic circumferential rim. A structural model of the elastic circumferential rim is created based on the requirements for stiffness of the elastic circumferential rim in the individual areas along the circumference of the elastic circumferential rim and the basic structure of the elastic circumferential rim. The elastic circumferential rim is manufactured based on the structural model of the elastic circumferential rim.
