This document presents information about smart textiles from a presentation by Shivani. It discusses that smart textiles are electronic textiles that can respond to their environment. There are different categories of smart textiles including aesthetic fabrics that change color or light up, and performance-enhancing fabrics that regulate body temperature or provide protection. The document also outlines the different types of smart fabrics from passive to active to ultra smart, and how they sense and react to their environment using sensors, data processing, and actuators. Some applications of smart textiles discussed are in healthcare for monitoring, defense for protection, and entertainment through interactive clothing.
