|By developing prosthetic devices that rely on implanting electrodes directly in nerves and remaining muscle, Chalmers University researchers aim to provide amputees with greater control over prosthetic movements.|
Researchers at Chalmers University of Technology (Gothenburg, Sweden) are developing a new method for controlling prostheses for amputees that relies on the power of osseointegration.
Since the 1960s, prostheses have been controlled by electrical impulses in the muscles. However, the technology for controlling these prostheses has not evolved greatly since then. For example, while advanced electric hand prostheses are available, their functionality is limited because they are difficult to control. “All movements must by preprogrammed," remarks Max Ortiz Catalan, industrial doctoral student at Chalmers University. “It’s like having a Ferrari without a steering wheel. Therefore, we have developed a new bidirectional interface with the human body, together with a natural and intuitive control system.”
