A robotic prosthesis as a functional upper-limb aid: An innovative review

© 2021 IEEE.There are many prostheses focused on people with an amputation below the elbow. There is also limited information for its development and construction, many studies provide information that helps the researcher, but these are scattered, each one proposing different characteristics and solutions. Based on this, the objective is to provide the researcher with a structured matrix that integrates different studies related to hand prosthesis, this will allow him to evaluate alternatives where he will be able to choose, analyze the study or characteristics that better contribute to his research topic. As methods, it used specialized search engines that helped to structure the matrix. Currently there is little information on prostheses based on encephalographic signals, so it was also incorporated into the matrix, likewise in the proposals it considers from 2 to 15 DoF (degrees of freedom), actuators used, and the classification of prostheses that are active, passive, electric, myoelectric and hybrid. In conclusion, the article will provide information to people who want to create a superficial extension below the elbow and make use of the control of electromyographic signals that are extracted from muscle contractions.
