Actualmente, múltiples estudios intentan establecer alternativas que permitan disminuir las consecuencias del gasto energético y los gases de efecto invernadero. En este sentido, la energía solar fotovoltaica se ha convertido en una opción factible para aplacar esta problemática, asimismo, se han buscado nuevas tecnologías para disminuir el gasto energético de los dispositivos refrigerantes, porque consumen emasiada energía y utilizan refrigerantes dañinos para cumplir su tarea. Por esta razón, las celdas Peltier pueden ser una opción viable para disminuir la temperatura en espacios cerrados sin generar residuos o emisiones nocivas. En el presente trabajo se plantea combinar estas iniciativas en un sistema unificado para aprovechar ambas tecnologías, implementando un sistema refrigerante que utiliza el efecto termoeléctrico para reducir la temperatura en su interior, que es alimentado por un sistema fotovoltaico autónomo utilizando algoritmos de seguimiento del punto de máxima potencia para mejorar su rendimiento. Los resultados reflejan que el dispositivo es capaz de disminuir la temperatura en su interior, permitiendo la conservación de elementos a temperaturas bajas y constantes, sin los inconvenientes de los refrigeradores comunes. Finalmente, se concluye que este sistema es una posibilidad plausible para sustituir las tecnologías de enfriamiento donde el acceso a la energía eléctrica es limitado.
Injuries in the elbow area, such as lateral and medial epicondylitis, are the leading causes of consultation with health specialists. Therefore, this research proposes the mechatronic design of an orthosis with a graphic interface that supports professionals in the rehabilitation of the elbow joint through the execution of flexion–extension and pronation–supination movements. For the development of the rehabilitation prototype, mechatronic design, co-design, and IDEF0 methodologies are used, performing activities such as actuator characterization, simulations, and modeling, among others. Through the execution of a case study in a real environment, the device was validated, where the results suggest a functional and workable prototype that supports the treatment of pathologies in the elbow area through the execution of the mentioned movements, supposing that this is a low-cost alternative with elements to improve, such as the industrial design and new functionalities. The developed proposal shows potential as an economical product that health professionals can use. However, some limitations related to the design and functionalities in the application domain were identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
