How Advanced are Prosthetic Arms?
The technology of prosthetic devices is constantly improving. The innovation in prosthetic hand design has seen experimental models frequently make the news over the past decade or so. The question 'how advanced are prosthetic arms' is therefore a difficult one to answer reliably, as the cutting edge in prosthetics is still making consistent progress.
The forefront of prosthetic research is centred around the method of control. What many companies pursue as the holy grail of prosthetic design is the perfect replication of a biological arm. In practice, this means their research is focused on intuitive control, the feeling of movement and the sense of touch.
