Abstract

See full text

The present invention relates to a method for producing microcapsules having a calibrated diameter and at least one parameter characteristic of the mechanical properties of an equally calibrated microcapsule, characterized in that the method includes the steps of: producing microcapsules by means of injection into a microsystem (10) of three fluids (f1, f2, f3); deforming the microcapsules by means generating a flow within a capillary tube (20); observing and acquiring the outline of at least one deformed microcapsule observed by an optical acquisition means (30); comparing the acquired outline with outlines from a collection of reference microcapsule outlines; determining the diameter and said at least one parameter characteristic of the mechanical properties of the observed microcapsule; and modifying the flow rates (Q1, Q2, and/or Q3) of the fluids (f1, f2, f3). The present invention also relates to a system for producing calibrated microcapsules.
