Low cost mechatronics prototype prosthesis for transfemoral amputation controled by myolectric signals

Abstract:

This article presents the development of low cost prototype prosthesis for transfemoral amputation leg, the prototype has not only low weight but also emulates the natural movement of a leg. It is activated by myoelectric signals obtained through the rectus femoris muscle of the amputated leg stump. Additionally, the prosthesis has a constant monitoring system of physiological parameters of temperature and humidity, this monitoring can be seen through an application for mobile phones. For this, the biomechanical analysis of gait was performed, after that the mechanical and electronic design, and finally test and results.
