👉 A flexible fluid is a substance that can flow and adapt to various shapes and surfaces, often found in nature or engineered for specific applications. It can take the form of liquids, gases, or even semi-liquid states, and is characterized by its ability to conform to the contours of objects it interacts with. This adaptability makes flexible fluids crucial in numerous fields, such as lubrication, where they reduce friction between moving parts, or in medical devices like catheters and prosthetics, where they can navigate complex biological structures. Their unique properties also enable innovative uses in soft robotics and adaptive materials, where flexibility and responsiveness are paramount.
