Conductive rubber as a sensor

Found this recipe at instructables: http://www.instructables.com/id/Conductive-Rubber-Make-Touch-Sensitive-Robot-Skin/ Has anyone played with this as a sensor? Any pointers or insights? I don't really want to make a "skin" but an odd shaped bumper or two might be useful on an open ADC pin-think a custom FSR...

I don't think I used enough carbon.  I get no conductivity across the surface.  Luckily I found a source for a HUGE amount of graphite for about $5/L.  A farm supply store, believe it or not.

Always after cheap robotic bits and bobs, thanks Max! Look forward to hearing how the next trial goes.


But it's been on my radar for a while now.  Since my intention (yup I'm a raw beginner @ robotics) is to build a robot pet I figure it'll come in handy. I will have a long touch (ie pat) give a positive reaction, and a short touch, or perhaps double layer touch (ie smack) be a kind of negative reinforcement.

What are you planning?
