Step 2Make a Stencil
Because we are making a bend sensor it makes sense to make it long so that it can be easily attached to where bending should be measured.
You do not have to follow the shape and size for this sensor exactly. I've kept it simple to communicate the idea.
Create a stencil that includes marking for stitches that should run diagonally. It is good to leave at least 5mm space between the stitches and the edge of the neoprene. Leave 1cm space between the stitches. It is about NOT creating a too conductive surface, so that the sensor stays sensitive. 4-7 diagonal stitches (depending on the length of your sensor) are normally fine. Also, they do not need to be long. 1,5cm max. For this version you'll want to leave about 1-2 cm space at each end of the sensor so that you can attach a popper, which will be useful for connecting it into a fabric circuit later on.
