Abstract

In this paper is reported about the development and characterization of Surface Acoustic Wave Sensors for ethanol vapors monitoring. The SAW devices are fabricated by inkjet printing a water-based solution of PDDAC (poly(diallyldimethylammonium chloride)) on commercial SAW resonators with nominal resonance frequency value of 433.92 MHz. A thin polymeric film acting as sensing element is achieved on the top of the piezoelectric substrate. The devices are characterized by means of custom oscillator circuits. The experimental activities regarding the Pierce like oscillator circuit development are also reported.
