For these prototypes, we painted the liquid graphite (no base) directly onto small piece of each substrate, then connected them to Arduino. Overall we found that the sonic success of this project is heavily dependent upon the fabric used. The woven jersey was the least responsive to the ink; it cracked under the pressure of pushing thereby losing the connection needed to sustain the connection. The spandex was very responsive; it did not crack and held the connection. The black elastic was by far the most responsive, but more out of line with our original concept. Our next step is to try silkscreening the pattern onto the fabric to see if it will hold the connections better.


The properties of spandex are friendlier than the jersey. The material absorbs the paint, so cracking is not an issue at this point in the usage process. The only “faulty” aspect is the warp of the fabric where the paint is, but I think this can be exploited with a different pattern printed onto the material.


This test went extremely well; the elastic absorbs the graphite thereby increasing and solidifying connections.

Woven Jersey

This is a first prototype for our final project in Soft Circuits. As you can see, jersey doesn’t hold the paint very well; all of the cracks prevent any type of connection. However, before the cracks occurred, this design produced a much more dynamic range of sound than a simple strip.
