Gallery: MIT’s Carbon Nanotube Pencil Draws Delicate Sensors onto Paper

 

Carbon nanotube sensors are a new must-have in contaminated areas, providing the ability to detect harmful gases and warn of danger. But the volatile nature of the sensors makes large-scale production a difficult task. Scientists at MIT however, have developed a new solution—a carbon nanotube mechanical pencil which with just a stroke of the point transfers a nanotube sensor onto a sheet of paper.
