They are still made of polymer clay, but with "a little" more inside...
First I shape the rolls as normal, but then I cut them open again on the underside before baking and install a 10KOhm resistor stuck in a piece of conductive rubber. I leave one leg of the resistance sticking out at the top.
Then the polymer clay is baked in the oven.
Then I cut off the excess wire flush and sand the claws into shape.
(It is important that the tip does not become too pointed in order to have sufficient support later)
After sanding, I roughen the first 2 cm again with 40-grit sandpaper
and make a small notch on the wire leg of the resistance.
I then solder a very fine silver wire there, then cover the tip with superglue
and the silver wire wrapped around the front 1.5cm of the claw with as few gaps as possible.
Then I fix it with some additional superglue and let the whole thing dry thoroughly.
Then I take a pea-sized amount of polymer clay and spread it very thinly over the front 2cm of the claw so that the silver wire and the roughened area behind it are covered. Then the claw goes back into the oven.
Now I fix the piece of conductive rubber again with a small drop of Kovulfix on both sides so that it can't fall out later and also smear about 1cm2 of Kovulfix on the underside of the claw at a good 1 cm distance from the tip
(This is so that the otherwise very smooth claw also has an area where it later has a certain "grip".)
This would be much easier with black claws, there is now conductive filament so you can theoretically print them quite easily.
