The impedance changes of lipid/polymer membranes with five basic taste substances were measured. Three types of membrane consisting of different lipid molecules showed different response characteristics for membrane resistance and capacitance for taste substances. In addition, sucrose, a nonionic taste substance, was detected by a large increase in membrane resistance, whereas other taste substances induced a decrease. This result differs from those of a recently-developed taste sensor, which exhibits output changes of the electric potential of lipid/polymer membranes for electrolytes. Therefore, taste sensing based on impedance measurement uses different information from potentiometric measurements, and hence will be effective for the detection of nonelectrolyte taste substances.
