This Bionic Finger Restores Amputees' Sense of Touch
Gary Cutlack | March 8, 2016
The paper from the Ecole polytechnique fédérale de Lausanne says that: "An amputee was able to feel smoothness and roughness in real-time with an artificial fingertip that was surgically connected to nerves in his upper arm. Moreover, the nerves of non-amputees can also be stimulated to feel roughness, without the need of surgery, meaning that prosthetic touch for amputees can now be developed and safely tested on intact individuals."

The bionic finger allows both amputees and non-amputees to distinguish between rough and smooth textures on a plastic plate. Signals from the finger are turned into neural signals with a computer algorithm (illustrated).
