Ingemar,

You mentioned an interest in an indicator that shows levels of humidity??
What sort of humidity levels are we talking about? what kind of
application? a diecut tape?

Would there be a commercial market for such indicators (say 1 M
units/year)? If so, would you want it to show a dunking in water (how
long reaction time at what temperature?) or exposure to high humidity
(what RH threshold at what temperature and reaction time?). I can
envisage several types of, say, 1210 pseudo-components with a colour
band which would change permanently (short of deliberate tampering).
They might not like aqueous cleaning though :-( Also, would you prefer
them to operate only in power-on conditions or at all times (service or
storage)?
