摘要
Colored oils and aqueous solutions have been electromechanically pumped in and out of arrayed microwells. The microwells comprised pyramidal pits in Si substrates that were coated with an aluminum electrode and a hydrophobic dielectric. These substrates were then suspended between volumes of water and oil. When colored oil was placed behind the substrate, surface tension forces caused the oil to completely fill the microwells and provide brilliant red coloration to the array. With application of similar to 30-50 V, electrowetting drove the colored oil behind the substrate and the reflection was made dominantly white.
