Despite enormous progress in the past two decades, the intentional control of bionic prostheses remains a challenge and the subject of intensive research. Now, scientists at the Medical University of Vienna and Imperial College London have developed a new method for precisely detecting the nerve signals remaining after an arm amputation and utilizing them to control an artificial arm. The study results, published in the journal Nature Biomedical Engineering, could form the basis for the development of the next generation of prostheses.
