Textiles today serve not only as protectors and comfort providers but also as attentive listeners to the language of your body. The inherent potential of textile technology has been used to create high-end and high-tech products that cater to markets that are not traditionally served by textiles. Smart textiles are one of such technological creations. It's clear that smart clothing means more than filling a number of cargo pockets of a battle uniform with computer equipment or putting electronic devices and batteries in it. It's a technology with an enormous degree of complexity. The innovative use of sensor technology and textile engineering to track minor physiological changes generated by the human body is one of the functions of the smart textiles. These smart textiles are therefore known for their ability of tracking and analyzing the vital parameters such as body temperature, respiration, heart rate, and muscular activity. They serve as monitors of one?s health and well-being through incorporation of sensors and conductors seamlessly.
