This article reports on the detection of droplets flowing in a microfluidic channel by performing electrochemical noise measurements. The microfluidic system with microelectrodes integrated in the channel was fabricated using standard microelectronic techniques. Droplets generated at T-junctions in the microreactor induce fluctuations of the impedance when passing between two electrodes flush with the floor of the channel. Experimental variations of impedance were measured using a specific
