Thanks
That would be interesting...how would it be done ? electrodes either side of it dry and then maybe pu......heck i'll be back in a minute lol, got a few unused shells in a bag still.
Ok, I tried a lobster crab type curly shell, because it may hold a barrier to any liquid.
Plain copper and galv steel electrodes showed 0.2mV dry. A couple of drops of rainwater were added and the reading went to 0.929V, but only 16uA. The voltage went down over a couple of minutes and stabilised at 0.710V. I'll expect it to drop off as the shell dries out.
Here it is running an LED oscillator, sorry about the pic quality. May well do more experiments with these shells.
Woah now! I just cottoned on to what you meant and tried the actual running seashell, with the same electrodes. Was seeing up to 198mV off the outer shell. Different readings in different places and only touching the tips of the electrodes to the shell. That was surprising
