Printed gas sensors based on electrolytes

C. Lucat, F. Menil and H. Debeda,     University of Bordeaux, France


In this chapter we present significant examples of solid electrolyte sensors. Lambda probes constitute one of the rare commercial success stories of gas sensors. The more recently developed proportional probes could still compete with them commercially with the development of lean-burn and diesel engines. Planar thick-film technology appears the most promising manufacturing process. It is cheaper and more versatile than traditional ceramic processes, with lower manufacturing costs and fewer ageing problems than planar thin film technologies. Although the measurement of oxygen partial pressure constitutes the leading ...
