<p><b>The diversity of the topics, as well as the expert subject-matter contributors from all over the world representing various disciplines, ensures the book is comprehensive and provides a broad understanding of smart nanotextiles.</b> <p>Smart wearables should be capable of recognizing the state of the wearer's surroundings and responding to them. Based on the received stimulus, the smart system processes the input and consequently adjusts its state/functionality of current predetermined properties. Smart textiles should also cater to requirements concerning wearability. Through the incorporation of nanotechnology, the clothing itself becomes the sensor, while maintaining a reasonable cost, durability, fashionability, and comfort. <p><i>Smart Textiles: Wearable Nanotechnology</i> provides a comprehensive presentation of recent advancements in the area of smart nanotextiles giving specific importance to materials and production processes. It shows the different materials, production routes, performance characteristics, application areas and functionalization mechanisms. It also provides a guideline to researchers and technologists who seek novel solutions in the related areas by including groundbreaking advancements in different aspects of the diverse smart nanotextiles fields such as nanofibers, nanosols, responsive polymers, nanowires, nanogenerators, and nanocomposites, and nanocoatings. <p><b>Audience</b><br> Researchers, technologists, and students in the fields of textiles, intelligent materials, electronics, sensors, actuators, biomedicine, materials science who have interest in smart materials, nanotechnology, and wearables.
