During the last decade, there has been both academic and industry interest in devising technologically advanced solutions for the improvement of mobility of people with a lower-limb amputation. This is due to the increased number of lower-limb amputees and the fact that the majority of current prosthetic solutions are energetically passive devices that are unable to restore full mobility to lower-limb amputees. This book chapter addresses SDG 10 by focusing specifically on lower limb prosthetics for amputees.
