Arrays of unheated chemically sensitive resistors (chemiresistors) can serve as extremely small, low-power consumption sensors with simple read-out electronics. The authors report results on carbon-loaded polymer composites, as well as polymeric ionic conductors, as chemiresistor sensors. In addition the solubility parameter concept is used to understand and categorize the chemiresistor responses and,, to compare chemiresistors fabricated from polyisobutylene (PIB) to results from PIB-coated acoustic wave sensors. One goal is to examine the possibility that a small number of diverse chemiresistors can sense all possible solvents, the universal solvent sensor array.
