What is a 'smart' material design tech?

'Smart' material design technology refers to materials that can respond dynamically to external stimuli, such as temperature, light, moisture, or stress. These materials can change their properties or behavior in response to environmental conditions, enabling applications in various fields like construction, textiles, and electronics. Examples include shape-memory alloys, self-healing polymers, and thermochromic materials, which enhance functionality and adaptability in products. This technology aims to improve performance, durability, and user experience in diverse applications.
