Carbon nanotube pencil leads used for drawing sensors onto paper

Carbon nanotube pencil leads used for drawing sensors onto paper: "

We’ve already seen a pen with silver-based ink, that lets its user draw electrical circuits on ordinary paper. Now, scientists from MIT have brought similar ‘hands on’ technology to the humble pencil – they’ve compressed carbon nanotubes together to form a pencil lead substitute, that has been used to draw gas sensors onto regular paper imprinted with gold electrodes...
