Ultra-Realistic Prosthetic Hand

Feb-20-16 By studying the human hand with an eye for its mechanics, researchers have created what may be the most realistic prosthetic hand yet.

The prosthetic, created by Zhe Xu andEmanuel Todorov from the University of Washington, is the result of a meticulous study of the human that involved scans of a human skeleton hand and 3D-printed bones that allowed the team to mimic the unique unfixed joint axes of the hand. Joint ligaments and tendons were made of Spectra, while laser-cut rubber sheets functioned as the soft tissue, tendon sheathing and the exterior hood. The muscles were duplicated with an array of 10 Dynamixel servos, which can closely mimic the human hand’s own carpal tunnel.

The result is a mechanical hand able to mimic almost all the operations of a human hand, and that relies more on construction rather than programming.
