The invention relates to a method for characterizing a fluid, implemented in a processing system (CPU) and with the aid of a measurement architecture. The architecture of measurement comprises a microfluidic device of the droplet generation type of a dispersed phase in a continuous phase, comprising a dispersed phase channel for receiving a sample of the fluid to characterize forming the dispersed phase and a phase channel continues for receiving a fluid forming the continuous phase and opening into the dispersed phase channel at a junction point. The method includes determining the dynamic viscosity (η _d) of the dispersed phase from the phase of pressure variation dispersed between the pressure at the inlet of the dispersed phase channel and the pressure (Pmffd) at the point of junction determined from a model and the disperse phase flow.
