One of my pet peeves is shoddy cellphone batteries. The ones where you charge it all day and then some, go out for a couple hours, reach in to your pocket to find it has shut down. I’m actually living with this at the moment and am in the market for a new mobile counterpart.
Scientists at Stanford university have come to the table with a solution, how about charging your device from the clothes you are wearing? Their design incorporates ordinary cotton and polyester, dubbed ‘conductive energy textiles’, these hi-tech clothes will charge your batteries.
Now i’m not one for being wrapped head to toe with some type of conductive possibly electro-magnetic field emitting pair of sweats, but if they can promise it won’t be charging me, I would give it a go.
Electricity is stored in the ink made from single-walled carbon nanotubes which is applied to the conductive energy textiles. The downside, you have to recharge your clothes at night.
In the photograph above: Porous textile conductor fabrication. (a) Schematic of SWNTs wrapping around cellulose ﬁbers to form a 3D porous structure. (b) Conductive textiles are fabricated by dipping textile into an aqueous SWNT ink followed by drying in oven at 120 °C for 10 min. (c) A thin, 10 cm × 10 cm textile conductor based on a fabric sheet with 100% cotton and Rs of 4 Ω/sq. (d) SEM image of coated cotton reveals the macroporous structure of the cotton sheet coated with SWNTs on the cotton ﬁber surface. (e) SEM image of fabric sheet coated with SWNTs on the fabric ﬁber surface. (f) High-magniﬁcation SEM image shows the conformal coating of SWNT covering and bridging between the fabric ﬁbers.
