Smart structures are advanced systems that integrate sensors, actuators, and control algorithms to monitor and respond to changes in their environment. These structures can adapt to various conditions, such as temperature fluctuations, vibrations, or loads, enhancing their performance and safety. Examples include buildings, bridges, and aircraft that utilize technology to improve durability and efficiency. The technology behind smart structures often involves materials like shape memory alloys and fiber-reinforced composites, which can change properties in response to stimuli. By using real-time data, smart structures can optimize maintenance schedules and reduce costs, ultimately leading to more sustainable and resilient infrastructure.
