Les capteurs électrochimiques microniques

Abstract
Presently, two main factors influence the evolution of both chemical and electrochemical sensors. The first is the very strong demand in sensors from various fields of industry. The second is the intrusion of microelectronic technologies in their fabrication processes which lead to the new concept of miniaturized sensors. The advantages of such small sensors are discussed. The various technologies of miniaturization used in the fabrication of electrochemical sensors are reviewed as well as the various methods of sensitization employed to functionalize the microtransducers, especially the Field Effect Transistors (FET).
