  Developing adhesives whose bond strength can be externally manipulated is a
topic of considerable interest for practical and scientific purposes. In this
work, we propose a method of controlling the adhesion force of a regular fluid,
such as water and/or glycerol, confined between two parallel plates by applying
an external electric field. Our results show the possibility of enhancing or
diminishing the bond strength of the liquid sample by appropriately tuning the
intensity and direction of the electric current generated by the applied
electric field. Furthermore, we verify that, for a given direction of the
electric current, the adhesion force can be reduced enough for the fluid to
lose its adhesive properties and begin exerting a force to move apart the
confining plates. In these circumstances, we obtain an analytical expression
for the minimum electric current required to detach the plates without
requiring the action of an external force.
