Abstract
This specification disclosed a partially closed microfluidic system and a fluid driving method. The microfluidic system is comprised of a substrate with microfluidic elements and a thin film. A feature of this structure is that the thin film is elastic and deformable. It has a single opening corresponding to a vent hole on the substrate, thus forming a partially closed microfluidic system. The substrate is designed to have several positions for micro fluid elements and deformable chambers and uses micro channels to form a complete network. Since the thin film is elastic and deformable, one is able to impose a pressure on the thin film above the deformable chambers in this partially closed microfluidic system to drive the fluid into motion. Once the pressure is released, the fluid flows back to its original configuration.
