▎ 摘　　要

NOVELTY - An electrowetting surface (100) comprises a substrate (110), electrodes (120, 122) on the substrate, and a nanoceramic coating (n1) over the electrodes. The electrodes contain a layer of conductive material deposited over the substrate. The nanoceramic coating contains ceramic nanoparticles (130) bonded together by a polymeric binder (140). USE - Electrowetting surface used in digital microfluidic device (claimed) used for controlling and moving discrete volumes (such as, milliliters, microliters, nanoliters, and smaller volumes) of fluids, dividing quantity of liquid into multiple droplets having known volume, separating specific species from other species in a liquid, and combining droplets containing different reactants to cause chemical reactions, or other applications. ADVANTAGE - The electrowetting surface can be used in digital microfluidic devices. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a digital microfluidic device, which comprises the electrowetting surface, a transparent top cover positioned over the electrowetting surface, and separated from the electrowetting surface by a gap to accommodate a liquid droplet between the transparent top cover and the electrowetting surface; and manufacture of the electrowetting surface, which involves depositing a layer of conductive material over a substrate to form the electrodes on the substrate, and depositing the nanoceramic coating over the electrodes. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the electrowetting surface. 100Electrowetting surface 102Liquid droplet 110Substrate 120, 122Electrodes 130Ceramic nanoparticles 140Polymeric binder
