Smart textiles are able to sense and respond to changes in their environment. They are also known as smart textiles or e-textiles. There are many emerging companies all around the world experimenting how we can implement technology into fabrics to create a more technologically advanced world.
Smart textiles are often used for aesthetic purposes. These smart textiles are primarily used in the fashion industry and usually light up or change color.

Smart textiles can also be used for performance enhancement, focusing on function over fashion. Using technology embedded in the fabrics, these textiles can regulate body temperature, reduce wind and water resistance, guard against radiation, minimize the effects of space travel, and control the vibration of muscles.

Smart textiles is a growing industry. Although few products have been successful in reaching consumers, with the increase of production and improvement of products, it will soon be a useful technology that can improve our health and safety and prove unique visuals and activities that were not possible before. I chose this topic because I am always interested in seeing how technology and art can intersect.
