is there a 'typical' depth of ITO layers?
<Noxz>
15-300nm seem to be readily available on precoated glass
<Noxz>
hrm, listed elsewere says common for 100A = 10nm
<Noxz>
for resistivity/reflectivity

k, new topic, QCM .. how can it be used to measure tension/force ?
<Noxz>
like, how would it be constructed
<Noxz>
I am imagining a hole drilled in it with a wire hook which is 'pulled' .. but not sure if this hole idea is correct
<Noxz>
... or a lever setup that pushes down/up against the QCM
<Noxz>
the application of interest is a surface tensiometer
<Noxz>
so there is a wilhelmy plate that would be the pbject that the liquids interact with, that plate is atatched via wire to the lever assembly which pushes down on QCM
<Noxz>
and it costs $1500 from china for one, heh
<Noxz>
for an automatic type, which I can imagine uses some small stepper setup
<Noxz>
stepper/stage

hrm, just thought of an idea for "contactless" measure to lengthen the life of the QCM from abbrasions .... magnets
<Noxz>
a magnet mounted on it, and another (same pols facing) on the lever
<Noxz>
in fact - that QCM could then even be encapsulated from dust
<Noxz>
:)
<Noxz>
not quite sure how the oscilating crystal's electric field woudl affect the magnet, if at all
<Noxz>
or maybe instead of mounting a magnet on it.. use Iron
<Noxz>
so it is still affected by the magnet on the lever
