A last significant
concept is the current density. It is the intensity
applied divided by the electrode's surface. It
is often calculated in mA/cm².
This value specify
a limit not to be exceeded at the time for
iontophoresis treatments. One can nevertheless put
the question to know why this limit is forgotten in
the other types of stimulation. Why limit calculation
to the intensity ? How to apply this formula to
the apparatuses with constant tension ?
