摘要：

A low voltage driven electrowetting on dielectric liquid focus lens was fabricated based on a tiny glass tube which had been coated with ITO (indiumtin oxide)-Al2O3-TiO2-Teflon multilayered thin films on the inside. Method of sol-gel/chemical solution dip coating was used for the film preparation. A cambered interface between silicon oil and aqueous solution containing NaCl and sodium dodecyl sulfate (SDS) was used for the lens refraction. The curvature of the interface was adjusted by changing the applied voltage. The contact angle of aqueous solution in oil atmosphere was reduced from 155 degrees to 67 degrees when -10 V DC was applied. The leakage current was only 28 nA at that applied voltage and its focal length changed from -2 mm to infinity then to 10 mm. (C) 2016 Elsevier B.V. All rights reserved.
