1. A method for fabricating a mechanical interface for connecting a biological body segment to a wearable device, comprising:
generating a digital representation of the biological body segment;
quantitatively deriving a digital representation of a segment-engaging surface of the mechanical interface from the digital representation of the biological body segment, the digital representation of the segment-engaging surface including a representation of an orthogonal impedance at each of a plurality of anatomical points, the orthogonal impedance being derived as a function of a body orthogonal impedance at a corresponding anatomical point of the digital representation of the biological body segment; and
fabricating the mechanical interface that includes a segment-engaging surface that is based on the representation of the orthogonal impedance at each of the plurality of anatomical points of the biological body segment.
