Design, construction and implementation of right biomechanical hand prosthesis

Abstract:

This paper presents the results of the processes of design, construction and implementation of a biomechanical prosthesis of right hand, as a first step is performed a study of the anatomy of the hand and according to these principles, define the basic movements that want to get into the prosthesis. Then calculated, designed and defined the mechanisms and materials from which will be built the elements of the hand considering the esthetic and ergonomics required for each part. Below, is designed and defined the control system the same which is based on signal handling using an optical sensor, this makes the prosthesis does not have in its structure any invasive element that might cause damage to the person who uses it. Finally the prototype is built and the implementation is done on a person with hand amputation and in the corresponding tests are obtained efficient results in relation to the mechanisms …
