Watch Carbon Nanotubes Give Used Chewing Gum a Second Life

Gum and carbon nanotubes sensor

You might think gum is useless once it’s been chewed, but researchers at the University of Manitoba and the Children’s Hospital Research Institute of Manitoba have a surprising new application for this sticky substance. By combining chewing gum with carbon nanotubes, they built a durable yet flexible motion sensor that could have a variety of health monitoring applications.

Watch this gum and carbon nanotubes sensor in action:

Researchers think these sensors could be used for tracking many different kinds of motion, including slow breathing. The sensors are highly adaptable since they are both strong and flexible and can be worked into a variety of forms. The current sensor can detect strains as high as 530% with a high sensitivity. It also has the ability to track changes in humidity.
