  • Powered ankle-foot prosthesis
    Patent number: 11278433
    Abstract: A powered ankle-foot prosthesis, capable of providing human-like power at terminal stance that increase amputees metabolic walking economy compared to a conventional passive-elastic prosthesis. The powered prosthesis comprises a unidirectional spring, configured in parallel with a force-controllable actuator with series elasticity. The prosthesis is controlled to deliver the high mechanical power and net positive work observed in normal human walking.
    Type: Grant
    Filed: November 6, 2018
    Date of Patent: March 22, 2022
    Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Hugh M. Herr, Jeff A. Weber, Kwok Wai Samuel Au, Bruce Wayne Deffenbaugh, Lee Harris Magnusson, Andreas G. Hofmann, Benjamin B. Aisen
