We’ve come a long way from eliminating static cling

Stanford University researchers aren’t stopping at paper when it comes to exploring how carbon nanotubes can be used to create thin, flexible batteries. They’ve moved on from paper and ink to cotton and polyester. Looking at combining carbon nanotubes and fabrics, the research team is bringing us closer to having wearable electronics and conductive fabrics.

The work, published in Nano Letters, expands on the science behind lightweight, flexible, and wearable electronics. Think about that cool turn signal jacket for cyclists that uses conductive thread and to make LED lights flash with just a touch of the hand to the sleeve. And all those concept designs for clothing that charges a device while you walk are a little less futuristic.

The researchers state that “with an extremely simple “dipping and drying” process using single-walled carbon nanotube (SWNT) ink” the fabric is turned into highly conductive textiles.

Industrial designer Jon West of Indakind Designs is making sure that rechargeable batteries have an even smaller carbon footprint, with a solar sticker that converts any rechargeable battery to a solar-powered one.

The patent-pending design is based on the use of flexible solar panels that can be wrapped around any rechargeable battery to help it harvest solar energy. The Solar Sticker comes with both the anode and the cathode, to make it easy to use.
