Resumen

This article presents the design of a customization-oriented transradial prosthesis for amputee patients, achieved through the use of parameters to construct an original 3D prosthesis model using Inventor software. The parameters were obtained by digitally processing images captured from the authors' hand, with established measures; for this purpose, some commands of the Toolbox Image Processing from MATLAB software were applied. In addition, the final test was performed with the participation of a third party, achieving an approximately accuracy of 93%. At the same time, an electronic circuit designed in EAGLE software, consisting of an instrumentation amplifier, a band-pass filter and a half-wave rectifier, was manufactured and tested for the acquisition of electromyographic signals, which were subsequently stored in digital format. Following the mechanical calculations after parameterization, the operation of the prosthesis was simulated using a graphical user interface designed in LabVIEW software, indicating the position of the actuators in relation to the type of signal acquired in real time.
