Light-activated polymers are materials that change their properties or shape when exposed to specific wavelengths of light. These polymers can be engineered to respond to different types of light, such as ultraviolet or visible light, allowing for precise control over their behavior. This makes them useful in various applications, including medical devices, smart materials, and robotics. The ability to manipulate these polymers with light offers advantages in creating responsive systems that can adapt to their environment. For example, they can be used in self-healing materials or soft robotics, where the polymer's response to light can trigger movement or repair processes, enhancing functionality and efficiency.
