Spiral wrappers switch nanotubes from conductors to semiconductors and back

By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.

Robotic touch sensors are not just skin deep

Researchers argue that the problem that has been lurking in the margins of many papers about touch sensors lies in the robotic skin itself.
