MZ_GeekChic_BadgeA team at Stanford University has produced batteries and basic capacitors using textiles and nanoparticle-infused ink.

The team had previously developed paper batteries and supercapacitors using a similar process, but the new energy textiles exhibited some clear advantages over their paper predecessors. With a reported energy density of 20 Watt-hours per kilogram, a piece of eTextile weighing 0.3 kilograms (about an ounce, the approximate weight of a T-shirt) could hold up to three times more energy than a cell phone battery.

Update: As @jasongreen points out on Twitter, that should be “0.3 kilograms (about 10 ounces…” [Thanks, Jason!]
