Fabrics are an old invention and have been important to us since ancient times. We choose different fabrics for their comfort or protection or both. For example, cotton absorbs moisture. And, this is a good thing, because the body doesn’t like wetness right next to the skin. The wetness feels clammy and it is very uncomfortable.

But in this age of technology, textiles will do more than make us comfortable. They will give us information, because they will have small bits of electronics embedded in them.

In fact, companies are now making wearable technologies to help NFL coaches monitor athletes by tracking their heart rate and their oxygen intake.

So when might you see smart shirt at your local store?

Well, engineers are working on them now. Ends up that a shirt is the worst place for electronics. Wearing a shirt or washing a shirt are demanding environments for any kind of electronics. They are the opposite of what electrical components prefer. Electronics like to keep dry and not bend.

These are major challenges engineers are solving right now. It seems in the future, we might need to charge our shirts. Or at least carry extra batteries.
