Some types of foam don't last long. I wonder if one
could make some with closed cell foam instead. It
last much longer but is a little stiffer than the
foam that they seem to be using.
If it is a capacitive you should be able to make
new capacitors with some aluminum foil and clear
tape.
Aluminized mylar is easy to come by in the form of mylar punched-tape
stock. It is quite expensive these days, but a single roll would go a
long way. Also, aluminized mylar is widely used in balloons and novelty
items, which could be harvested for material. I have no idea if the
thickness is critical, but this sort of material would likely be much
more conformant than aluminum foil.
