Abstract

Digital microfluidic two-phase flow systems have achieved an impressive degree of flexibility and versatility. Yet, the primary generation of drops is generally still controlled solely by the imposed flow rates of both continuous and dispersed phase and the resulting hydrodynamic forces. Here we present a novel method to overcome this lack of precise on-demand control of the drop generation using hybrid microfluidic channel systems with incorporated electrowetting functionality. Using a fixed flow rate ratio in combination with freely programmable electrical waveforms on the electrodes, arbitrary sequences of drops with variable volume (≈ 0.5fL ~ 1.6pL) can be generated.
