Etude de la reconfigurabilite de circuits RF par des réseaux fluidiques. Conception et fabrication de microsystèmes, intégrés sur substrat souple

Microfluidics is a relatively new field, it really appeared in the early 90s. But this area has experienced strong growth and has reached maturity that allows it to intervene in a wide range of applications, chemical, biological, genomic, optical ... This growth was made possible by the development of specific technology and particularly technologies by polymers. The thesis presented here is therefore based on the technological expertise of the laboratory in microfabrication to achieve a coupling between microfluidics and microwave and thus expand even further its range of application. One of the current challenges for emission-reception circuitry is reconfigurable miniaturization of passive components. Tunable filters by means microfluidics have been studied to characterize the design, through manufacturing an important work. This is based on the technique of laminating dry film SU-8 and helped integrate microfluidic channels for substrates microstrip filters. Circulation of distilled water showed very good results in terms of shifts in the center frequency. Other lines of liquid-interactions microwaves are also presented using filters such as a sensor element as chemical or biological.
