I have an application that needs a large number of very small, cheap,
penumatic valves.  They won't need to be particularly accurate, fast,
leak free, or handle alot of pressure.

As a possible solution, I was wondering about a "sphincter valve,"
a short piece of tubing like material that relaxes/opens when it has
voltage/current/heat/?? applied.

Does such a material exist ?   Other suggestions ?
Thanks in advance.
