Imagine a T-shirt that could monitor your heart rate or blood pressure. Or a pair of socks that could provide feedback on your running stride. This futuristic idea is getting closer to reality, thanks to new research from Washington State University. Scientists there have developed a more durable and comfortable way to print electronic materials onto fabrics, creating "smart" textiles. Unlike earlier attempts that relied on stiff or rigid components sewn or glued onto fabrics, this new method uses a direct ink 3D printing technique. Researchers printed a solution containing carbon nanotubes and a biodegradable polyester onto two types of fabric. This solution bonded well with the fibers, making the printed materials wash-friendly and able to hold up through abrasion.
