Pressure Conductive Rubber

[muragavino]

Can anybody help me in finding electrical conductive rubber which changes its el. resistance when pressed?

There is a known material called CS57-7RSC (CSA) from Yokohama, but it is hard to find some sample here in europe.

If somebody has knowledge/experience in this matter she/he would make me very happy by replying to this post.

FYI, the material described in US Patent 4,273,682 is probably what you're referring to (or similar). You can view a copy of the patent here:

Since the patent was issued in 1981, it's expired (in the US), so maybe someone else can mix a similar composition for you.
Good luck!
