Abstract
Esta investigación presenta un estudio detallado sobre el desarrollo y la integración de piel sintética en prototipos de prótesis impresas en 3D. Se realizaron experimentos para medir la conductividad térmica de los dedos anular, meñique, índice y pulgar de la prótesis, utilizando gráficos lineales para documentar la evolución de la temperatura bajo condiciones de estrés térmico. Los resultados mostraron un aumento lineal y constante en la temperatura de cada dedo, evidenciando una conductividad térmica estable y una respuesta predecible de los materiales utilizados. Se evaluó el impacto de la incorporación de piel sintética en el prototipo de prótesis de mano. La investigación demostró que la piel sintética no solo mejora la estética y la interacción táctil de la prótesis, sino que también podría incrementar la aceptación del dispositivo por parte de los usuarios. Sin embargo, se identificaron desafíos relacionados con la durabilidad y la sensación táctil de las pieles sintéticas, lo que señala áreas clave para futuras mejoras. piel sintética en la prótesis. Se enfocó en la optimización de la adhesión, la armonía estética y las propiedades físicas de la piel sintética, culminando con ajustes significativos en su diseño y composición. Estos ajustes resultaron en una mejora notable en la similitud de la piel sintética con la piel humana, así como en su funcionalidad en aplicaciones protésicas. En conclusión, este estudio aporta conocimientos valiosos en el campo de las prótesis. Los hallazgos tienen implicaciones significativas en el diseño de prótesis más realistas y funcionales, contribuyendo al avance de la ingeniería de prótesis y la mejora de la calidad de vida de los usuarios.
This research presents a detailed study on the development and integration of synthetic skin into 3D printed prosthesis prototypes. Experiments were conducted to measure the thermal conductivity of the prosthetic ring, pinky, index and thumb fingers, using line graphs to document the evolution of temperature under thermal stress conditions. The results showed a linear and constant increase in the temperature of each finger, evidencing a stable thermal conductivity and a predictable response of the materials used. The impact of incorporating synthetic skin into the prototype hand prosthesis was evaluated. The research demonstrated that the synthetic skin not only improves the aesthetics and tactile interaction of the prosthesis, but could also increase user acceptance of the device. However, challenges related to the durability and tactile feel of the synthetic skins were identified, pointing to key areas for future improvements. The study also covered the development of methodologies for effective integration of the synthetic skin into the prosthesis. It focused on optimizing the adhesion, aesthetic harmony and physical properties of the synthetic skin, culminating in significant adjustments to its design and composition. These adjustments resulted in a marked improvement in the similarity of the synthetic skin to human skin, as well as its functionality in prosthetic applications.In conclusion, this study provides valuable insights into the field of prosthetics. The findings have significant implications in the design of more realistic and functional prostheses, contributing to the advancement of prosthetic engineering and the improvement of users' quality of life.
