Some DIY sensors from Ian McCurdy (maybe still based in Ireland?)

PDF of some fantastic textile-based sensors for wearable (and hopefully washable) tech that could easily be adapted to electronic music. I'm getting mental images of a severely yarn-bombed modular synth!

I am also still toying with the idea of making some quantum-tunnelling composite material by mixing nickel nanoparticles with silicon rubber to make some force-sensitive resistors with a squishy quality. the nickel nanoparticles are very spiky and when the spikes are closer together, quantum effects cause electrons to jump between them. so, when you squish the stuff, the resistance goes from pretty much non conductive to very conductive.
It does look like the inventors have tied up the patents very thoroughly, so it might be perilous to actually make and sell something. In theory, even home-made versions can be seen as a violation of patents, especially in the USA.
Also, I'd like to make sure the nickel particles are not touched by the player's skin as they might be irritant.

I had a play with the black anti-static foam that came with some chips I bought. It conducts electricity, but has some resistance. So, when you squash it, it effectively becomes denser as the air gaps in the foam close up.
Putting some foil on top and underneath the foam let me measure the change in resistance with pressure. It's pretty effective. Of course, foams tend to deteriorate over time, so this kind of sensor would probably make a crappy product, but it's pretty neat to play with. I would use copper foil instead of aluminium though because the latter oxidises pretty quickly.
