MICROFLUIDIC DEVICE WITH VARIABLE VOLUME MATERIAL

摘要

The invention concerns a microfluidic device comprising at least one first plate (112) forming the substrate and having at least one perforation (113) and, on either side of said first plate (112), in at least several locations, a material for delimiting channel portions, said material consisting, in at least one of said locations, of an activable material capable of varying its volume by activation, said material being arranged at said locations based on an arrangement which enables, during a first phase and upon activation of at least one location consisting of said activable material, its transformation from a first configuration into a second configuration, modifying a three-dimensional network corresponding, in the second configuration and depending on the selected location(s) which are activated in the first phase, to different paths of the liquid having several channel portions (117, 119) parallel to the plane of the first plate (112), located in offset planes, at least on either side of said first plate (1112), and between which is located at least one of said perforations (113).
