SAW-controlled drop size for flow focusing

Lab Chip, Vol. 13 (9), pp. 1691-1694 (2013)
We demonstrate the regularization of droplet formation by applying a surface acoustic wave (SAW) localized at the flow-focus junction of a drop maker. This allows electronic control of drop size in real time, without changing the flow rates or microchannel dimensions.
