  • Variable impedance mechanical interface
    Patent number: 11883307
    Abstract: 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.
    Type: Grant
    Filed: October 5, 2020
    Date of Patent: January 30, 2024
    Assignee: Massachusetts Institute of Technology
    Inventors: Hugh M. Herr, Andrew Marecki, David M. Sengeh
