Abstract: A flow system (1) comprising a first part (2) and a second part (3), the parts (2, 3) being made from materials having different coefficients of thermal expansion. The first (2) and second (3) parts are positioned relatively to each other in such a way that when the ambient temperature changes corresponding changes are caused in a flow channel (4) formed in the first part (2), thereby changing the flow resistance of the flow channel (4). Thereby a change in flow resistance caused by a change in viscosity of a fluid being transported by the flow system (1) can be counteracted. The resulting flow resistance of the flow system (1) is thereby at least substantially independent of the ambient temperature. Furthermore, a micro fluidic system comprising the flow system (1). The micro fluidic system may be or form part of a medical device, a fluid analysis system, e.g. a device for measuring blood glucose levels of blood samples, or an infusion device.

Abstract: A tubular elastomer actuator with a shape in a cross-sectional view which shape exposes at most one single axis of symmetry of a specific length, e.g. an oval shape. The actuator could be made from a sheet made from a plurality of plate shaped elements which are laminated together and rolled. Each plate shaped element may have a corrugation that gives the element an anisotropic structure, and contains an electrode on only one surface. The actuator displacement is the result of shrinkage displacement of the plate shaped elements upon the application of electrical field across their thickness.

Abstract: A micro-mixer (8) is disclosed having at least one mixing point (9, 10) which is connected to an inlet channel arrangement having at least two inlet channels (3, 4) and to an outlet channel arrangement, and a mixing method is disclosed for at least two fluids which are supplied from different directions. With this mixer and method it is intended to achieve a rapid and predeterminable mixing of the fluids. For that purpose, a separating element (5) which extends into a region of the mixing point in which the inlet channels run parallel to one another is provided. By this means the fluids can be kept separate from one another until their flow speeds virtually coincide in respect of value and direction. Only then are they brought into contact with one another.
