There are three main types of smart textiles! First, 
active smart textiles change in response to the environment.  π
For example, some fabrics can change color when it gets hot. Second, 
passive smart textiles donβt change but can sense things, like how much you sweat.  π¦
Third, 
interactive smart textiles can communicate with devices!  π±
For instance, a jacket could connect to your phone and tell you the 
weather. Some cool types of smart textiles include smart sports wear, heated jackets, and even smart diapers!  πΆ
