Imagine if your shirt could track your heart rate as you run, or if it could charge your cellphone on the go. Innovative fashion designers and engineers, who are pushing the envelope with "smart textiles," dream of designing garments that are not just embedded with devices, but actually are the devices. Welcome to the world of wearable computing.

The development of smart textiles is a true fusion of fashion and technology. From manipulating nanoparticles in cotton, to incorporating knit antennas and transistors into garments, the computational fashion industry is reimagining how we use clothing in our everyday lives.

"Can garments become the actual device?" said Genevieve Dion, assistant professor and director of the Shima Seiki Haute Technology Laboratory at Drexel University in Philadelphia. "My dream is to have nothing hard on [clothing], and no batteries that need to be put into the garment, no small pods that need to go into the pocket. Is it possible? Maybe."
