Conductive yarn with carbon nanotubes

Conductive yarn with carbon nanotubes


Here’s an interesting article on Nanowerk about coating cotton yarn in carbon nanotubes (CNT) to make it conductive. While still a ways off from DIY use, this is an intriguing step forward for wearables! Looks like they could learn a thing or two about making a sewable LED, though. (Thanks, Sean!)

From the Maker Shed:

Lilypad E-Sewing Kit

The LilyPad e-sewing kit contains the bits to sew LEDs into any piece of clothing. Add turn signals to a jacket, accentuate a t-shirt, or light-up your favorite pair of jeans with this simple to use kit. This kit contains the very basics to the LilyPad system. It’s a great entry-level kit for people who want to experiment with wearable electronics. Consider adding the LilyPad Pro Kit to extend control and use of the LilyPad system.

    So what happens when the carbon nanotubes inevitably break off, and you breathe them in? Carbon nanotubes look to be extremely bad for your lungs…

    Yeah, I’ve been warned that toxicity is a big problem with this, another reason it’s not ready for prime time!
