title: SAW-controlled drop size for flow focusing.
abstract: 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.
