Abstract
The invention relates to an electrically-opened micro fluid-valve. The inventive valve comprises: at least one planar support (); at least one afferent microchannel (); at least one efferent microchannel (), said microchannels being arranged in the support (); such that at least one of the ends (and) thereof touch the inner face () of the support close to one another; at least one deposit () of a heat-sensitive material which is disposed on the inner face () of the support (); and at least one heating means (). According to the invention, the aforementioned deposit () of heat-sensitive material at least partially seals the space separating the ends (and) of the microchannels (and), thereby preventing same from intercommunicating. When the temperature of the above-mentioned heating means () is raised, the structure of the heat-sensitive material is altered, thereby at least partially opening the ends of the microchannels an the space therebetween, in order to enable communication between said microchannels and to restore the flow of the fluid.
