Microsystems, microsensors, microfluidic

Starting from the example of a lab-on-chip for biological analysis, the issues related to the integration of different components and functions on a miniaturized system will be developed and clarified. An introduction to microfluidics (physics at the microfluidic scale, influence of the laws of scale on the miniaturization of systems, hydrodynamics of microfluidic systems, diffusion, mixing and separation in microsystems) as well as the notions necessary for understanding the problems of Acquisition of the very low amplitude signal will be presented. The cases of chemical and biological sensors will be particularly developed.
