|20130220528||Method of Fabricating Bubble-Type Micro-Pump - A manufacturing method of a bubble-type micro-pump is provided. At least a bubble-generating unit is provided on the bubble-generating section. Because of the varied surface energies on the top of the bubble-generating section, the varied backfilling velocities of the fluid of the front end and the rear end cause fluid moving when a bubble vanishes. The top surface of the bubble-generating section is subjected to a particular surface treatment to form a surface energy gradient. Examples of surface treatment include sputtering a thin film with varied densities or thickness, radiating one or multi-layer thin films by a laser beam, etc.||08-29-2013|
