After Big Bang

For the first time, robotic prostheses controlled via implanted neuromuscular interfaces have become a clinical reality. A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.

« Going beyond the lab to allow the patient to face real-world challenges is the main contribution of this work, » says Max Ortiz Catalan, research scientist at Chalmers University of Technology and leading author of the publication.

« We have used osseointegration to create a long-term stable fusion between man and machine, where we have integrated them at different levels. The artificial arm is directly attached to the skeleton, thus providing mechanical stability. Then the human’s biological control system, that is nerves and muscles, is also interfaced to the machine’s control system via neuromuscular electrodes. This creates an intimate union between the body and the machine; between biology and mechatronics. »

The direct skeletal attachment is created by what is…
