18.If you're the kind of person who won't leave the house without a sports watch,it may soon be time to get rid of it.Inventors have issued a new digital running shirt,which has all the features of an electronic tracking device and more.
The"D-Shirt"is made from a special fabric(織物) woven with sensors,which record your heart rate,GPS location,route,speed and altitude.
The shirt,which is lightweight and washable,sends the information to an app on your smartphone by Bluetooth.The phone can store and analyze data from the fabric,showing the person's route,time,heart rate and number of calories burned.It can also help indicate when the runner is pushing himself too hard and risking the heart attack.
"We believe that our connected lives in the future should not be more complicate.They should be easier.So we are developing technology which does not require people to change their habits,"said Stanislas Vandier,deputy chief executive."You never leave home without a shirt.So we are simply turning a T-shirt into D-Shirt.In the future,the same principle can be applied to all sorts of clothes."
Developers are now working on heart,breath and sweat sensors,so this shirt can be particularly helpful for people in extreme conditions,such as athletes,first responders,and soldiers.It is hoped that in the future,other factors such as blood oxygen level can also be monitored using the fabric.
