Designed prosthetic leg with realistic foot
Source:
When one walks on uneven surfaces, full of potholes and stones, feet help him to distribute the load and keep the balance. Largely responsible for this ankle and fingers, but a prosthetic leg can't boast of having such moving parts. This issue was relevant as long as the researchers from Stanford University created a design that responds to bumps like a real foot and prevent lameness.
Designed prosthesis has three rubber contact points with the surface of the two front "toe" and one rear "heel". With built-in sensors of the pressure exerted on these points, electric toes and heel to move independently up and down, distributing the loads and maintaining maximum contact of the denture with road irregularities. In addition to sensors, the prosthesis is equipped with a gyroscope, which helps to determine the location of the feet as well otprygivat leg at the end of each step.
thea New prosthetic leg will prevent the lameness
At the beginning of the study, the prosthesis was tested only inside a computer simulation. She imitated the gait of the man, and allowed developers to understand how to behave in the prosthesis. After the virtual testing, the prosthesis was tested by a volunteer with an amputated leg — the progress and result of the study can be seen on video.
The Researchers hope that this invention will create the most realistic artificial legs. The main thing is to keep them reasonable cost because of expensive prostheses are not available to everyone.
Unlike artificial legs, artificial hands are improving with greater activity. In early 2019, the engineers of the company Integrum AB and at Chalmers Institute of technology created a robotic arm that is able to handle the items. More about it can be read in .
To Discuss this and other topics of science and technology . Also it is convenient to monitor the fresh material.
