Our results demonstrate that the printed sensors can selectively detect the target analytes at 28°C. The sensor’s selectivity is correlated to their Hansen solubility parameters (HSP), and their response dynamic is adjusted by the polymer glass transition temperature (T g ). Using the principal component analysis (PCA), we demonstrate that the selected polymers can successfully discriminate between chemically diverse analytes. Hence, showing the potential of inkjet-printable polymer composites with representative HSPs as low power and cost-effective VOC sensors. Such sensors can be readily integrated with wearable and flexible electronics.Chemiresistive VOC sensorPolymer nanocompositeInkjet printingRoom temperatureLow powertext::conference output::conference proceedings::conference paper
