L'invention concerne un dispositif microfluidique comprenant au moins une première plaque (112) formant le substrat et présentant au moins une perforation (113) et, de chaque côté de cette première plaque (112), en au moins plusieurs emplacements, un matériau apte à délimiter des portions de canaux, ledit matériau étant formé, en au moins un de ces emplacements, d'un matériau activable (114, 116) pouvant faire varier son volume par activation, ledit matériau étant agencé auxdits emplacements selon une disposition qui permet, lors d'une première phase et par activation d'au moins un emplacement constitué dudit matériau activable, la transformation depuis une première configuration vers une deuxième configuration, ce par quoi est modifié un réseau tridimensionnel qui correspond, dans la deuxième configuration et selon le choix du ou des emplacements qui sont activés dans ladite première phase, à différents parcours de liquide présentant plusieurs portions de canaux (117, 119) parallèles au plan de la première plaque (112), situées dans des plans décalés, au moins de chaque côté de cette première plaque (11), et entre lesquelles se situe au moins une desdites perforations (113).
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 functionalized photocurable perfluoropolyether is used as a material for fabricating a solvent-resitant microfluidic device. Such solvent resistant microfluidic devices can be used to control the flow of small amounts of a fluid, such as an organic solvent, and to perform microscale chemical reactions that are not amenable to other polymer-based microfluidic devices.
