Fluid flow system used for separation of e.g. cell from fluid e.g. blood, has polymer actuator that is coupled with channel structure and is operated for changing flow cross section of barrier used for obstructing particles in fluid

摘要

The fluid flow system (11) has a channel structure (15) for the flow of fluid. The barriers (19) are formed in the walls of channel structure for obstructing the particles (21) in fluid. A polymer actuator (14) is coupled with channel structure and is operated for changing the flow cross section of barrier.
