The present work treats the development of an Assistive Technology product, based on studies of the Brazilian scenario on upper limb prosthetics. The goal was to develop a low-cost and open-source transradial prosthesis, that allows the rehabilitation of basic human hand movements, encouraging the development of collaborative technologies and 3D printing in Brazil. It begins by addressing the key players involved in the development, such as the design applied to the open-source model, followed by a presentation of relevant data on amputations and prostheses.
This stage was conducted back and forth with medical professionals. An evaluation chart was created to quantify the best aspects of each idea. The final result tries to combines every positive aspect with manufactured feasibility.
Developed along with engineers and medical specialist. In order to create a function prototype to validate the feasibility of the idea and technology.
Part of the technology developed is registered as a Patent, because of its disruptive innovations on how to fix the product on the upper-limb and the finger activation mechanism. Nevertheless, the academic article is open and accessible to everyone in the world, reaching over 200 downloads per year since 2018. All the data e research is available following the open-source principle. The ultimate goal of this project is to impact the development of 3D printing and electromyography in Brazil.

Patent no. br 23078.015329/2018-12
