HAND PROSTHESIS WITH VOLUNTARY OPENING Tendon-Driven Hand The application of various principles of underactuation led to the design of an auto-adaptive tendon-driven hand. Just as the human hand, the fingers have three phalanges linked together with cylindrical joints. A tendon-driven mechanism allows the fingers to close in a natural manner. Each finger has a single actuator for three degrees of freedom (DOF). These are thus under-actuated and in this way obtain an adaptable ability. A fourth d

After transhumeral amputation, four patients had implantation of a self-contained, osseointegrated prosthesis with a neuromusculoskeletal interface that allowed intuitive control of the prosthetic hand and arm over 3 to 7 years. A video shows use of the prostheses in daily life. https://nej.md/2Kr5LEq | The New England Journal of Medicine
