Acquisition card and myoelectric signal treatment for three-channel trans-radial prostheses

Abstract

With the advancement of technology, it has been increasingly successful to improve the construction of prostheses as
extensions of a member of the human body. For the functionality of many of them, it is necessary to use acquisition cards and signal
processing. In the case of trans-radial amputations, the connection area or socket is small, which leads to the problem of how to
implement a card that is capable of acquiring three signals and decreasing the number of electrodes to be connected. To meet these
requirements we proceeded to design a first prototype with the main goal of being a light, small and three-channel measuring system. A
common ground configuration was used in order to decrease the number of electrodes. In this way, it has great impact and functionality
in the area since it will be possible to continue the rest of the research in the field of control systems applied to myoelectric prostheses.
This article describes the process of designing, implementing, testing and analyzing results.
