I was checking out Fast Company the other day and saw a great article about an artificial hand that is so advanced that its wearers can sense surfaces with their fingers.
as I dug deeper, I came across this video from the inventors of the project:
As you can see, sensation is restored by three small electrodes implanted on the nerves of the wrist, close to where the hand connects. The hand was developed at Cleveland Veterans Affairs Medical Center and Case Western Reserve University. Wearers say the prosthetic hand begins to feel more like a part of the user’s body, thanks to these sensors. I can imagine that those who are able to wear one of these are thrilled to be able to regain the sense of touch!
