Abstract:
1. A method for mixing at least two fluids, said method comprising: introducing the at least two fluids into a mixing chamber, said mixing chamber comprising a piezoelectric component for mechanical actuation of fluid motion within said mixing chamber, said piezoelectric component comprising at least first, second, third, and fourth actuation domains, the first and third actuation domains being on first and third opposed sides of the piezoelectric component, and the second and fourth actuation domains being on second and fourth opposed sides of the piezoelectric component; actuating the first and third domains at a first phase of a frequency of oscillation thereby causing the first and third sides to oscillate in unison and alternatively in first and second opposed directions; actuating the second and fourth domains at a second phase of the frequency of oscillation thereby causing the second and fourth sides to oscillate in the first direction when the first and third sides oscillate in the second direction, and in the second direction when the first and third sides oscillate in the first direction.
