Abstract
A microfluidic valve including a microchannel, a membrane arranged so as to seal off the microchannel and equipped with resistive units, characterized in that at least one face of the membrane includes at least one groove, and in that the resistive units are arranged in the groove and are capable, when an electric control current flows through them, of expanding sufficiently under the effect of the heat produced by the flow of the electric current to cause the rupture of at least one part of the membrane.
