Adaptive structures are systems designed to change their shape or properties in response to external conditions. This adaptability allows them to optimize performance, enhance safety, or improve energy efficiency. Examples include buildings that adjust to weather changes or bridges that can flex under heavy loads. These structures often utilize advanced materials and technologies, such as smart materials and sensors, to monitor their environment. By integrating these elements, adaptive structures can respond in real-time, making them suitable for various applications, including aerospace, civil engineering, and robotics.
