Nanotube plastic makes cotton smarter

  November 10/17, 2008
Coat cotton thread with a mix of carbon nanotubes and electrically-conducting plastic and you have a material for making smart clothing and bandages.

The nanotube-infused polyelectrolyte coating allows the thread to conduct electricity like wire. The thread's electrical properties can be made to change in response to changes in humidity and in the presence of substances like blood.

Smart thread can be readily manufactured into clothing and bandages, opening the way for wearable sensors and smart bandages that can be used to monitor people's physical conditions.
