Smectic liquid crystals

Smectic liquid crystals are a type of liquid crystal that have a layered structure. In these materials, the molecules are arranged in parallel layers, allowing them to flow like a liquid while maintaining some order like a solid. This unique organization gives smectic liquid crystals special optical and electrical properties, making them useful in displays, sensors, and other technologies. They can change their orientation and thickness when exposed to electric fields, enabling precise control of light, which is valuable in modern electronics, particularly in screens and monitors.
