1. A mixing element for a microdevice comprising:
a) a mixing compartment having a principal axis of symmetry in fluid communication with a channel and
b) first through fourth pairs of electrically coupled, elongated mixing electrodes located on the interior surface of the mixing compartment wherein:
(i) the first electrodes of the first and second mixing electrode pairs are adjacent and parallel to one another and aligned axially with respect to the principal axis of symmetry;
(ii) the second electrodes of the first and second mixing electrode pairs are adjacent and parallel to one another and aligned with a plane orthogonal to the principal axis of symmetry;
(iii) the first electrodes of the third and fourth mixing electrode pairs are adjacent and parallel to one another and aligned axially with respect to the principal axis of symmetry; and
(iv) the second electrodes of the third and fourth mixing electrode pairs are adjacent and parallel to one another and aligned with a plane orthogonal to the principal axis of symmetry.
