Abstract: A microfluidic device of the present invention is connected to at least an inlet to permit at least a stream of fluid with a desired fluid flow rate and a stable laminar flow. A body with at least a non-deformable portion and a deformable portion is connected to the inlet. At least a microconduit of substantially reduced length and cross-section, integrally formed in said non-deformable and deformable portions, and connected to the inlet. The stable laminar flow of fluid transiting through the microconduit is disrupted, resulting in a turbulent flow of the fluid, with a vibration of the deformable portion, when the fluid flow rate crosses a threshold value. The turbulent flow of the fluid undergoes an enhanced mixing, in a reduced period of time. At least an outlet is connected to microconduit to collect the mixed fluid. A network of microfluidic devices are arranged to perform mixing of fluids.
