Development and integration of screen printed transducers for the detection of pollutants in aquatic environments

In this paper, we present the study and the integration of screen-printed transducers for the detection of pollutants in water. In the first part, we discuss the use of acoustic transducteurs screen-printed and the technique to measure ultrasonic velocity in order to detect pollutants miscible or not with water. In the second part, we present the fabrication and test of screen-printed transducers to measure the electrical conductivity in liquids. And finally we also ensure the adaptation and integration of these transducers with electronic modules.
