This is made possible thanks to pressure points on the artificial sole of the foot. The information is then conveyed to the stump of the amputated leg. The artificial foot was developed on the basis of a natural one, with the corresponding distribution of pressure from the front part to the heel. Being able to identify the surface on which one walks is made possible by reacting nerve ends to serve as conveyors of information from the sensors in the prosthetic leg.
Hubert Egger of the Department for Medical Engineering at the University of Applied Sciences Upper Austria, who developed the prosthetic leg in collaboration with his team, hopes to be able to identify small or medium-sized producers “which cannot afford their own research work.” The thought-controlled prosthetic arm has now become suitable for daily use, and was given approval in 2014 by the Food and Drug Administration in the USA.
