LOAIZA, JAIR L.  y  ARZOLA, NELSON. EVOLUTION AND TRENDS IN THE DEVELOPMENT OF HAND PROSTHESIS. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.169, pp.191-200. ISSN 0012-7353.

In this article, the evolution and challenges about the hand prosthesis development are presented. Besides, the main characteristics about the recent international designs, which contain the considerate number of functions, several degrees of freedom and high physical performance are shown. Additionally, some results related to hand prosthesis models and prototypes obtained in Colombia are exposed. At the end, several physical-mathematical models that emulate with the mechanical behavior of the biological tissues are shown and a set of intelligent materials of interest for the hand prosthesis production are identified. As the conclusion, it is stated that this device development in simultaneous engineering environments, where the latest results of bionics, control, automation, new materials and productions techniques could be integrated, will ease the development of the hand prosthesis with the indistinguishable characteristics from the real hand; both in functionality and appearance.
