Hmmm And this is different from many humidity bi material sensors going back several hundred years? Lots of stuff swells differentially with water. This is pretty flexible and extreme. Years ago the father of a friend invented a gadget that would open a valve when the water in a swamp cooler built up the solubles that could damage the cooler.

Yes, very cool. I wonder why we can create smart objects and yet people seem to be getting duller and duller. The two are probably not related…and yet?
