Can piezoelectric film "go bad"? We acquire an exhibit that had a large
surface area of piezoelectric film: it is intended for younger visitors to
make handprints on it that slowly disappear. It suddenly stopped working.
Can direct sunlight affect the film? Magnets? Any ideas on how to get it
to make images again?
Thanks.
