Abstract :
Embedded sensors based on printed organic semiconductors are attractive for use in product content monitoring due to their low cost. Arraying multiple sensor elements, in a bridge topology, yields signatures that achieve high specificity using non-specific elements. The output signal is amplified and digitized to detect numerous analytes with up to 10ppm sensitivity. A wine-spoilage application is demonstrated
