This 6M bobbin of 26AWG Superflex wire is a soft and supple, ideal for wearable technology.
We have worked with many wearable projects, and the weakest point always seems to be the wiring. Regular PVC-coated multistrand wire is ok for electronics, but it's simply not designed for the bending abuse seen on a wearable piece. Here's one part of the solution - Superflex wire!
Superflex wire is constructed of 8 strands of tinned enamel-insulated 36AWG (0.127mm / 0.005" diameter) wire, wrapped around a nylon thread core. This makes it very flexible, somewhat like embroidery thread, but puffier.
We first used Superflex wire on our Superflex LEDs strings with great success, incorporating them into many wearable projects, and immediately saw the need for just raw wire with other wearables. Using it is a bit different than regular wire because of it's unique construction. When we were using it to wire up individual addressable LED strings pixels, we came up with the following method, which works very well when you need an even number (2/4/6) of wires:
We are presently doing experiments with sewing machines, and Superflex does not seem to like the extreme bends necessary in our Bernina to be in the bottom spool. We will post results with other machines as we get them.
Although super flexible, pretty, and robust, SuperFlex wire doesn't behave much like regular wire when soldering. Here's how to prepare the wire before soldering it into your project:
