According to figures presented by the INEI, in the last 8 years, the number of Peruvians suffering from some type of disability has doubled. Contrary to the supposed demand, in our country prosthetic devices are expensive and scarce, which makes it difficult for patients with loss of the upper or lower limb, due to amputation or in cases of congenital deficiency, to have access to them. In light of this reality, this research was developed with the aim of designing and building a 3D-printed myoelectric prosthesis to compensate for the loss of functionality in adults due to transradial amputation. For this purpose, the systematic approach of Pahl et al. (2007) for engineering design, Zwicky's morphological matrix, static structural simulation with SolidWorks software, and EMG signal processing for hand opening and closing in three types of grips: tripod, medium wrap, and disc precision, were applied. This prosthesis is designed to offer practical and effective solutions, allowing patients to perform daily tasks more independently. A functional prototype capable of performing the required grips was designed and built. It began with the conceptual design in which the solution concept was selected using technical and economic criteria. The mechanical system of said concept was modeled and simulated with the use of SolidWorks software. For the design of the electronic system, the Arduino IDE was used, this was used in the reading of EMG signals and programming of the control algorithm. Finally, for the construction of the prototype, national acquisition materials were used for a total cost of 570 nuevos soles. For the evaluation of functionality, a protocol developed from the AHAP protocol was used, as a result, a device capable of performing tripod grips and medium wrap without difficulty was obtained. In this way, it was verified that the prototype met the requirements established at the beginning, being a viable solution to serve as a technology to help people with transradial amputations.
