Acoustic Devices as Chemical and Biochemical Sensors : Principles and Applications

Résumé

This lecture will cover devices based on acoustic waves and used for materials characterization and sensor applications. For example, Rayleigh SAW sensors are extremely sensitive to mass change (100 pg.cm-2) and are generally used for gas concentration measurement. We will focus on a particular platform which is known as one of the most sensitive: the Love-wave device or shear horizontal SAW (SH-SAW). Sensing applications will be presented with a particular interest in chemical detection in gas and/or liquid phase. To demonstrate the potentialities of Love waves platform associated, in such cases, to microfluid devices, few examples like immunodetection of E. Coli and phycotoxins, heavy metals and complex fluid characterization will be exposed.
