You can make a whole circuit using conductive thread and fabric.
Here is some tips, DOs and DONT DOs.. that are learned from many mistakes we made in our past trials.
DO:
- Design the circuit on computer (especially if you do more than 1 layer) and print on iron on Tshirt print paper. Be careful, you are going to sew from back side, so you do NOT need to mirror the image.
- Set the conductive thread as a bottom thread (thread in the bobbin). Bottom thread does not go through needle hole, and it does not fray as much.
- Use small patch of conductive fabric as connection point. You can also sew over other line to make a connection.
DON’T:
- Pay attention which conductive thread you are using. Some thin threads are quite high resistance and it does not work on circuit. (it lowers the current too much) It helps to sew more than one time for each line to lower the resistance per connection line.
- Be careful when you make a knot at the beginning or the end of the thread. It tends to fray and open and make a false connection. You can sew back and force to secure the stitch, or use fabric glue to secure your knot.
