Smart materials, also known as intelligent or responsive materials, are designed materials that can be significantly changed in a controlled manner by external stimuli such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds. By activating its functions, smart materials technology allows us to adapt to environmental changes. Traditional coating technologies transport the sensing and responding properties of smart materials for active coating to textiles. Depending on the trigger, these bioinspired materials can change their dimensions, solubility, colour, and shape, among other things.
