Abstract

In this paper an improved method for the on-demand production of droplets in a microfluidic device is presented. Earlier work reported by our group has shown that a pressure source generated by high frequency Surface Acoustic Waves (SAW) can be used to produce water in oil droplets on-demand in a microfluidic system, an ability with a wide range of potential applications [1]. Here we demonstrate that SAW actuation parameters can be finely tuned to create precisely controlled droplet volumes down to femtolitres. Importantly, we show that the use of finely tuned, focused SAW pulses provides the versatility to operate in multiple droplet formation regimes.
