Did you know that rubber conducts electricity ? Ok it's conductivity is 10^-14 s-m, but if faced with a kragagooogle volt of potential, it will conduct. Carbon fibre conducts rather better... which can be a worry if you are in a sail boat in a thunderstorm.. but to be a useful conductor we are looking for 10^6 s-m or better, better than, or close to copper. What does this stuff do? The article does not relate.

- flukus 10y agoThe only google results come back here, so I'm guessing it's a place holder word for "a lot", like a bajillion.
- inopinatus 10y ago"kraga" appears to be a swedish word meaning "flange", so hopefully that clears things up.
- Groxx 10y agoGoogle guesses Icelandic for me, which apparently translates as "collar". Seems obvious in retrospect.
- paulmd 10y agoAlso, there are various forms of conductive rubber available. Typically this is done by mixing carbon powder into the rubber. https://en.wikipedia.org/wiki/Conductive_elastomer https://en.wikipedia.org/wiki/Conductive_elastomer
- flashingleds 10y agoThis summary doesn't give numbers, but the journal article being discussed does. About 3e3 to 1e4 S/m for different preparations, compared with zero for untreated silk. Performed as a two-probe DC measurement, so once you factor in contact resistance it might be even better. The details are scarce, so you'd probably want to see it repeated more carefully before concluding anything.
