The ‘Superheroes’ project: Design and fabrication of low-cost personalized prostheses

Abstract

Limb absence has an impact on the physical, psychological, and social well-being of individuals, particularly those with upper limb deficiencies. Myoelectric prostheses, controlled by voluntary muscle contractions, can restore some functionality; however, they are costly, complex, and inaccessible, particularly for children who require frequent updates as they grow. In order to address these limitations, the "Superheroes Project" was developed at University of Oviedo. This interdisciplinary initiative engages students from engineering and healthcare disciplines in the design and fabrication of low-cost prostheses with 3D printing technology. The project guarantees that each prosthesis is tailored to the specific requirements of the individual, with a focus on comfort, adaptability, and user-friendliness. Digital modelling of the residual limbs is performed for the prostheses design, which are then manufactured with additive technologies of lightweight and flexible materials. 13 individuals from Spain and Cambodia have been benefited from the project, with devices tailored for several activities ranging from daily tasks to sports. In addition to the physical benefits, the project also promotes social inclusion and transforms student participants by enhancing their technical and interpersonal skills. The Superheroes Project demonstrates that affordable customized prostheses can improve the quality of life of patients, while fostering a deep connection between education and community service.
