Advanced Robotic Prostheses Control

Purpose and goal

The objective of this project was to develop a permanent bidirectional osseointegrated interface to permanently communicate implanted electrodes with artificial limbs, thus providing physiologically appropriate signals for control and the possibility of artificially input sensory feedback.

Results and expected effects

The development and implementation of such interface allowed, for the first time, the permanent implantation of neuromuscular interfaces in an amputee (electrodes in nerves and muscles). Thus improving functionality in activities of the daily living as well as professional. Previously neuromuscular interfaces have only been used within research laboratories, the technology we have developed now makes these interfaces clinically relevant.

Approach and implementation

This was a close collaboration between Integrum AB, Chalmers University of Technology, and the Center of Orthopedics Osseointegration (COO), Sahlgrenska University Hospital (SUH). This was a truly multi-disciplinary project where the synergy of the different medical and engineering fields was the key for success.
