Stimuli-responsive materials

Stimuli-responsive materials are smart materials that change their properties—such as shape, color, or stiffness—in response to external triggers like temperature, light, pH, or pressure. These changes can be reversible or irreversible, allowing the material to adapt to its environment or perform specific functions. They are used in various applications, including drug delivery systems that release medication when needed, sensors that detect environmental changes, and self-healing materials. Essentially, these materials can 'sense' changes around them and respond appropriately, making them valuable for advanced technological and medical uses.
