A chemical sensor presents information about the chemical composition of its environment (either liquid or a gas phase). The information provided by this sensor would be in the form of signals that is correlated with the concentration of analyte, a certain chemical species. Recognition and transduction are the two main steps in the operation of a chemical sensor.
