The demand for a low-cost transradial prosthesis project, to meet the needs generated by the loss of an upper limb, is present worldwide more and more every day. Mainly because of the high manufacturing cost of an Electromyography (EMG) Prosthesis and the fact that the affordable prices would be related to Aesthetic Prosthesis - without any functional benefit to the user. Therefore, it is necessary to make these technologies more accessible to the public and the community. Make the information easier to access to empower users and increase the reach of this product. Hence, the need to design an open-source functional prosthesis that can meet basic user needs. That’s how my bachelor thesis started to get shape and form.
In Brazil, the development of 3D printed prostheses is limited explored. Therefore, having this project within the open-source universe boost for this field to be extended. This project also encourages the development of professionals prosthetics forcing the market to present fairer prices and more innovative features to be competitive. The difficulty was in balancing the different areas of health, electronics, systems, and mechanisms within the user's needs and project constraints. Because it is not enough to have just functionality; the person must feel comfortable and protected while handling it, and the visuals must be pleasing to the eyes.
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.
During the user's interviews, one need was clear, the personalization. New technologies allow products to be easily manufactured and personalized. On the left side, the prosthesis is representing with 3D patterns. On the right side, the prosthesis is thematic from a Brazilian soccer team.
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.
