Electrowetting Actuation of Polydisperse Nanofluid Droplets

Figure 4

Change in droplet curvature and base diameter due to electrowetting actuation for deionized water: (a) at 0 V; (b) at 10 V. For a 0.5 μm nanofluid droplet, (c) a smaller contact angle at 0 V and (d) an enhanced electrowetting response at 10 V are observed.
