Chopping Carbon Nanotube Yarn with an Axe (Part 2!)

Tyson took a trip to the Class Axe Throwing range in Dallas, TX recently, so it seemed like the perfect time to make a follow-up to the recent video in which we demonstrated our carbon nanotube yarn surviving an axe blow. In this new video, we see how well some of our yarns and films survive when an axe is thrown at them!

A big thank you to the folks at Class Axe Throwing for letting us perform this fun test at their range, and for helping us out with some of the throwing!

Carbon Nanotube Yarn with Nylon Insulation

We’ve had a couple of questions about our ability to apply electrical insulation to our carbon nanotube yarn products, so we wanted to provide you with a video showing off what we are currently able to do. We don’t yet have the equipment necessary to apply polymer or rubber insulation to our CNT yarn, but we are able to put a braided jacket of nylon thread around the yarn, as shown here!

We’ve recently added one grade of nylon-insulated CNT yarn as a product in our online store. We can apply this kind of insulation to other grades of CNT yarn as well; if you are interested in this, you can request a quote using the contact form at https://dexmat.com/contact/ or by writing to us at info@dexmat.com!

Carbon Nanotube AUX Cable

In this video, we demonstrate an auxiliary cable made with carbon nanotube (CNT) conductors and shielding. The cable has two CNT yarn conductors that are insulated with a nylon braid and then shielded with a CNT fiber braid. The sound quality is great and highlights the tremendous potential for CNT materials in high-end audio cables!

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!

DexMat Carbon Nanotube Yarn + Sewing Machine

Here we show the first part of the process of making a simple wearable electronic display in a t-shirt using our carbon nanotube yarn. We use a standard sewing machine to stitch several long filaments of our yarn into the shirt; we plan to eventually connect these to a battery, an Arduino, and some LEDs.

The CNT yarn is strong enough and flexible enough to be run through the sewing machine without being damaged, but it is somewhat less flexible, and much less stretchable, than cotton yarn; as a result we did have some trouble, as you can see in this video. In the end, the carbon nanotube yarn worked well when it was fed from the bottom bobbin. It worked well when fed from the top bobbin and stitched into thick fabric, but not so well with the more elastic t-shirt fabric.

Complications aside, this video demonstrates the potential of our carbon nanotube fibers and yarns for use in e-textiles. It is possible that with more time and knowledge we may have been able to troubleshoot the problem…if you are a wearable electronics maker, why not get some of our yarn and see if you are able to make it work? 🙂

Update: check out our video of the completed shirt here!

Carbon Nanotube Yoyo

We are still working on the sewing machine video that we promised last week, but in the meantime, we wanted to put together a fun demonstration of the flexibility of our carbon nanotube yarn. Here we have replaced the cotton string on a yoyo with a length of our carbon nanotube yarn. The yarn is flexible enough for the yoyo to work perfectly, and as you can see it is strong enough for Dmitri to perform a few tricks.

High strength 130 micron CNT yarn spotlight

In this video we focus on one of our newly available products, a higher strength version of our 130 micron diameter carbon nanotube yarn.

DexMat at Interwire 2019

DexMat is at the Interwire 2019 expo in Atlanta, GA, to talk about our carbon nanotube yarns and films. If you are in the area from May 14 – May 16, come by booth 154 and say hello!

CNT Film Impact Test

In this video we perform an “amateur” impact test on a sample of our carbon nanotube film by striking a razor blade into it with a hammer. The CNT film is compressed, but not torn or damaged.
