Chopping Carbon Nanotube Yarn with an Axe

Some time ago, we uploaded a video showing how well a sample of our carbon nanotube film was able to hold up to an impact from a blade. In this video, we take things a step further by trying to cut some of our carbon nanotube yarn with an axe!

Spoiler warning: it survives better than that piece of wood does.

Wearable Electronics: Carbon Nanotube Yarn + LEDs

This is the follow-up to our previous video, in which we demonstrated how our carbon nanotube yarn could be stitched into fabric using a conventional sewing machine. Here we are showing off the finished product: a DexMat t-shirt with blinking LEDs embedded into our lightning bolt logo!

We used an Arduino Gemma and a small battery pack (sewn into a pouch near the hem of the shirt) to create this LED effect. The electrical connections between the Arduino and the LEDs consist of 4 lengths of our high strength 130 micron carbon nanotube yarn. As Tyson demonstrates, this yarn can easily bend and fold with the shirt, and the zig-zag stitch allows it to stretch as well. It’s also extremely light and comfortable!
