Plastic microfluidic structures having a substantially rigid diaphragm that actuates between a relaxed state wherein the diaphragm sits against the surface of a substrate and an actuated state wherein the diaphragm is moved away from the substrate. As will be seen from the following description, the microfluidic structures formed with this diaphragm provide easy to manufacture and robust systems, as well readily made components such as valves and pumps.

Micromechanical flow limiter with multilayer structure, e.g. for medical infusion system - has intermediate diaphragm layer which deflects w.r.t. amount of flowing medium, and blocks flow for large flow amounts

The micromechanical flow limiter is formed from three layers (1,2,3) fixed on top of one another. The middle layer (2) functions as a diaphragm and comprises a flat structure with a central opening (8). On both sides of the opening, walls (9,10) block or open the flow path. The flow limiter operates passively, without an actuator. The limiter is controlled by the prevailing pressure differences. In order to increase its reliability, additional micromechanical elements may be coupled to the multilayer structure. USE - For preventing back-flow in medical dispensing systems. Also for laboratory, motor vehicle, aircraft or space vehicle use or for pneumatic controllers.

A micro valve and a method for setting or actuating a micro valve for use in fluidic applications includes cooling an array of actuating members made of Shape Memory Alloy (SMA) material. The SMA material is cooled to a temperature equal to or below the temperature at which a transformation from austenitic to martensitic state occurs so that the entire array of SMA actuating members is either fully or partially in the martensitic state. At least one of the actuating member is selected to correspond to a pre-determined opening pressure or flow resistance. Each of the actuating members are heated individually, except the previously selected one, to a temperature equal to or above the temperature at which a transformation from the martensitic state to the austensitic state occurs.
