Abstract

The cybernetic interface within an upper-limb prosthesis facilitates a Human-Machine interaction and ultimately control of the prosthesis limb. A coherent flow between the phantom motion and subsequent actuation of the prosthesis limb to produce the desired gesture hinges heavily upon the physiological sensing source and its ability to acquire quality signals, alongside an appropriate decoding of these intent signals with the aid of appropriate signal processing algorithms. In this paper we discuss the sensing and signal processing aspects of the overall prosthesis control cybernetics, with emphasis on transradial, transhumeral and shoulder disarticulate amputations, which represent considerable upper-limb amputees typically encountered within the population.
