The coupling of an electrical field with an ultrasound field has focused special attention from a fundamental point
of view. In 2003, Compton et al [17] reviewed the main results in this field. We can find in literature not only work
done under ultrasound on typical electrochemical processes with simple molecules [18] and macromolecules [19],
but also analysis about the mechanical effects of the ultrasonic field propagation on the electrode surface such as
acoustic streaming and microjetting [20], electrode cleaning [21] and general aspects [22-23] related to the mass
transport [24-25]. Cavitation and shock waves have also received attention [26-27].
