Clothes with

nanotube ink

FED up with your MP3 player running out of juice? Maybe your shirt could help. A newly

developed carbon-nanotube-based ink that can soak into fabrics could turn clothing into wearable batteries.

Yi Cui and colleagues at Stanford University in California created the ink, made with single-walled carbon nanotubes. The team dyed porous fabrics with the ink to create a conductive textile with very low resistance. The fabric maintained performance after repeated washes, suggesting that the ink is durable.

Cui says it’s possible to treat the dyed material with an

electrolyte to create a fabric capacitor capable of storing and releasing electrical charge. That, he says, means the technique could be harnessed 1 .
