I guess I don't even remember what I've read these days. I was rummaging
thru the ole O2 patent pile, and there is indeed one in there that's
built strickly from a TiO2 film, sorta like a hot-wire anemometer. And
it does INDEED measure the stoich transition based on a sudden change in
resistivity at stoich. Wadaya know, contradictin meself once again.
