The new development of Italian scientists is the SoftFoot Pro prosthesis, suitable both for people who have lost a foot and for the robots of the future. It reproduces the natural movements of the bones when walking on different types of surfaces, transmits newatlas.com.
The prosthesis allows the foot to bend and stretch, providing stability on uneven or sloping surfaces. SoftFoot Pro adapts to any conditions, minimizing discomfort and providing a more natural movement.
Its design consists of five parallel chains connected to a titanium heel. The front segments of each chain simulate the movement of the fingers, while the rear segments reproduce the movement of the metatarsal bones.
The arch mechanism allows the SoftFoot Pro to store energy by flexing the toes at the end of each step and then release that energy as the foot lifts off the ground to take the next step forward. When the prosthesis hits the ground, its flexible design allows it to absorb between 10% and 50% of the impact energy.
The prosthesis weighs 450 grams and can withstand a load of up to 100 kg. So far, it has successfully passed clinical trials on volunteers with amputated limbs. The participants were able to overcome unevenness and inclines, squat down and stand up without effort.
