Bionic Hands? Not An Improvement on Mechanical Hooks!, Says User

Right now, says a woman born without a left hand, electronic prostheses don’t function as well as mechanical extensions

Writing in the engineering journal IEEE Spectrum, Britt H. Young looks at bionics from the perspective ofa user. Her left forearm failed to develop prenatally. She offers a number of concerns about the direction of bionics, especially the expense of bionic limbs and their difficulty of use compared to simpler prostheses: Today, the people who design prostheses tend to be well-intentioned engineers rather than amputees themselves. The fleshy stumps of the world act as repositories for these designers’ dreams of a high-tech, superhuman future. I know this because throughout my life I have been fitted with some of the most cutting-edge prosthetic devices on the market. After being born missing my left forearm, I was one of the first cohorts Read More ›

Prosthetic Hand Controlled by Thoughts Alone? It’s Here.

Decades ago, no one could control a prosthesis only by thought. There is lots of room for the field to grow still

A key problem for amputees is that the nerves in the remaining part of a limb used to control a prosthesis usually produce only tiny signals. They are often hard for the nervous system to distinguish from mere noise. So, to control the limb by thoughts, the signals must be amplified. A new technique uses muscle grafts to amplify the signals.
