The skin resistance is in the megaohms range for dry, unprepared skin.
Most of the bio-feedback/lie detector type circuits I have seen ask you
to use a contact gel (saline solution works in most cases) like the ones
used with ECG/EKG electrodes. The skin resistance (actually I should
say the body impedance?) under such conditions is reported as in the
range of 500 to 1000 ohms. I suppose the lie detectors must be
measuring the body's response as a whole (to stress) than just skin
resistance.

Try out your scheme with good skin contact to see if any variation is
noted.

A conclusion is the place where you got tired of thinking.

You know, they have been tested and it works. Maybe put out some
custom designs later, once one has been designed and tested.
Anyway, thats my opinion.
