... ble agreement with predictions from the models developed. Abstract Electrical actuation of liquid droplets at the microscale offers promising applicati of microfluidics and lab-on-a-chip devices. Much prior research has targeted the electr electrically conducting liquid droplets; however, actuation of dielectric droplets has rem unexplored, despite the advantages associated with the use of a dielectric droplet. This modeling and experimental results on the electrical actuation of dielectric droplets betwee A first-order analytical model, based on the energy-minimization principle, is developed electrical actuation force on a dielectric droplet as it moves between two flat plates. Two analytical model are benchmarked for their suitability and accuracy against a detailed n The actuation force prediction is then combined with available se electrical actuation. Electrical actuation of dielectric droplets is experimentally demonstrat transformer oi
