Previously, I had blogged about XS Labs who conducted a few remarkable "pulp-based computing" exercises back in 2006.
The latest in paper and electronics experiments comes from Leah Buechley Leah uses a mixture of magnetic and conductive ink for her conductive traces. She has also made custom electronic components embedded with magnets that adhere to conductive traces. To activate the electronics, she is using the resistance of the body.
The problem with conductive inks on textiles is that over time they tend to crack as the fabric is bent (normal inks do this too). The cracks lead to issues of conductivity. I've spoken with manufacturers that promise their inks are less resistive to cracking when silkscreened on specific types of fabrics but those particular inks are fairly toxic to work with.
I love the idea of using conductive inks for pulp-based computing. I think it would be really interesting if someone could translate this idea into conductive inks silk screened on clothing.
