Abstract EN
Passive knee prostheses require a significant amount of additional metabolic energy to carry out a gait cycle, therefore affecting the natural human walk performance.
Current active knee prostheses are still limited because they do not reply with accuracy of the natural human knee movement, and the time response is relatively large.
This paper presents the design and control of a new biomimetic-controlled transfemoral knee prosthesis based on a polycentric-type mechanism.
The aim was to develop a knee prosthesis able to provide additional power and to mimic with accuracy of the natural human knee movement using a stable control strategy.
The design of the knee mechanism was obtained from the body-guidance kinematics synthesis based on real human walking patterns obtained from computer vision and 3D reconstruction.
A biomechanical evaluation of the synthesized prosthesis was then carried out.
For the activation and control of the prosthesis, an echo-control strategy was proposed and developed.
In this echo-control strategy, the sound side leg is sensed and synchronized with the activation of the knee prosthesis.
An experimental prototype was built and evaluated in a test rig.
The results revealed that the prosthetic knee is able to mimic the biomechanics of the human knee.
