- Abstract
Antisymmetric, symmetric and standard actuation of acoustofluidic devices were compared in terms of focusability. By imaging the end part of an acoustophoresis separation channel while flowing fluorescent beads through it, we show that beads get more tightly focused by antisymmetric actuation than symmetric and standard actuation at a given electrical input power. This means that antisymmetric actuation is more suitable for single node acoustic focusing as lower input power can be used to reach the same level of performance, or higher throughput can be reached for the same power.
