This paper illustrates a new method for creating air separated droplets on demand at a microfluidic T-junction in a microchannel using electrowetting-on-dielectric (EWOD). This new mechanism enables digital control of droplet formation that is not achievable by conventional continuous flow T-junction systems. The developed system can be used for dispensing droplets for biomedical applications including high-throughput screening without further liquid processing.
