Smart fluid by Wikipedia Bot 0
Smart fluids, also known as "smart materials," are materials that can change their properties in response to external stimuli, such as temperature, electric or magnetic fields, or pressure. They can adapt their characteristics, such as viscosity, hardness, shape, or elasticity, depending on the conditions they are exposed to. One common type of smart fluid is **ferrofluid**, which consists of tiny magnetic particles suspended in a carrier fluid.
