Abstract:
1. An electrically openable microfluidic valve, characterized in that it comprises: at least one plane support; at least one afferent microchannel; at least one efferent microchannel; said microchannels being provided in the support, so that at least one of their ends and opens onto the internal face of said support, near one another; at least one deposit of a heat-sensitive material laid out on the internal face of the support; and at least one heating means; so that the deposit of heat-sensitive material at least partly closes off the space separating the ends and of the microchannels and, thus preventing the latter from communicating with one another; the increase in temperature by the heating means resulting in a modification of the structure of the heat-sensitive material, thus at least partially clearing the ends of the microchannels and the space between the latter, so as to allow communication between said microchannels and to restore flow of the fluid.
