Carbon nanotube dye may put a capacitor in your shorts
How would you like it if your phone started charging whenever you dropped it into your pocket? That may eventually be possible, thanks to a carbon nanotube-based ink that can turn many common fabrics into conductors, or even components of a charge-storing supercapacitor. These won’t be showing up in a clothing store near you anytime soon, however, as ensuring that the fabrics only direct the charge to appropriate devices and not, say, to a sensitive body part will be a separate engineering challenge.
