Good video which let us really understand the process.
The foam gives good results on the oscope from what I see. Although the foam of ear plugs seems to have low shape memory, which is also mainly my problem with the carbon foam I got for electro static protection.
I wonder if using a more shape reactive foam with your conductive ink would help to get better results.
For the others that want also to make some tests with other sort of conductive foams, here is the link to my finger sensor parts and tuto:
The thicker you make the Foam the faster it will spring back.... which is one reason I found the elastic memory foam to have an edge over others I have tested.
In the video I exchanged the thin foam insert show with a Whole 3M ear plug....indeed it does squash down to 2mm or less (from 20mm). Its the 20mm version that is shown operating in the video on the Oscope.
Gareth, You are a prompt
Gareth,
You are a prompt tester!!! Thanks very much.

Thicker = Springy
