👉 A linked fluid, often found in the context of advanced materials and composites, is a type of fluid that exhibits properties where its flow is intricately connected and responsive to external stimuli or changes in its environment. This fluid can adapt its viscosity, conductivity, or other physical properties based on factors like temperature, pressure, or electric/magnetic fields. In materials science and engineering, linked fluids are used to create smart materials that can self-adjust their characteristics for optimal performance in various applications, such as adaptive coatings, responsive biomedical devices, and advanced sensors. Their unique behavior allows for innovative solutions in fields ranging from aerospace to biomedical engineering, where dynamic and responsive materials are crucial.
