does not create the effect, either.)
The finger-brushing effect appears to be due to
a combination of factors that are both electrical and
chemical. It is known that a high voltage electrical charge
will cause polar molecules to orient themselves according
to the electrical field impressed on them. (Polar
molecules have a non-uniform electrical distribution. One
part is positive and the other part is negative.) Water is a
highly polar chemical.
Additionally, most complex organic molecules are
polar. The result is that there is an electrical attraction
during the pulse because of the molecular orientation. (A
negative pulse causes the positive parts of the molecules
to orient towards the plate. These positive/negative
charges attract each other.) When the pulse is over, there
is no attraction.
This results in a variable friction when the finger is
moved. The friction is higher when the pulse is on and
lower when the pulse is off. The variation in friction is not
noticed if the finger is stationary. A close analogy is
rubbing a nail over a file. The ridges in the file cause a
variable friction. Rubbing the nail over the file causes a
vibration to be felt. A stationary nail does not vibrate.
It has been noted that there is person-to-person
conduction of the vibration effect (and other effects).
There is no sensation at all when this occurs. (In fact,
1/4” sparks can be drawn into or out of a person without
sensation. This requires a much more powerful apparatus
and special conditions.) It appears that this conduction
occurs because of the molecular rotation of polar
molecules (as noted above).
This is very different from an ordinary electrical
current because there is no free movement of electrons.
The polarization of molecules causes a charge shift that
is propagated like a bucket-brigade. Since there is no free
electron movement, there is no measurable electrical
Consider this analogy. Suspend a number of bar
magnets with threads so that they can easily rotate. Keep
them far enough away from each other that they do not
pull together, but keep them close enough that their
magnetic fields overlap. If this is done properly, they will
orient themselves into a straight line. This simply shows
the magnetic attractive force.
Now, manually rotate any magnet 180°. All of the
other magnets rotate, as well. By forcing a local change
in the magnetic field, a magnetic effect is propagated
