“Robotic” textiles could help performers and athletes train their breathing, and potentially help patients recovering from post-surgery breathing changes.

A new kind of fiber developed by researchers at MIT and in Sweden can be made into clothing that senses how much it is being stretched or compressed, and then provides immediate tactile feedback in the form of pressure, lateral stretch, or vibration. Such fabrics, the team suggests, could be used in garments that help train singers or athletes to better control their breathing, or those help patients recovering from disease or surgery to recover their breathing patterns.
