I tried again to make another cable prototype yesterday afternoon.
Signal “Wire” Layer
Applying the First Shield Layer
Applying the Second Shield Layer
My sewing was not entirely straight, so I’m not sure how well the prototype will carry audio signals. There may even be shorts between the layers. My next step is to test the “cable” with an audio signal. I want to try the wearable cable with a microphone to see how much noise my homemade cable produces. I also need to terminate the shield and signal wires with rings so I can solder wires or other connectors to them.
I’ve had another idea about how to make the cables: if I use wider strips of conductive fabric, I could make piping with a stitch of conductive thread down the middle. This would be easier to construct than my second prototype.
I’ve discovered that three layers of fabric and the associated stitching produce a fairly stiff package. I’m not sure if this will work well for creating curved “wire” paths in clothing.
