An "artificial tongue" for calibrating solution flow characteristics of taste stimulus delivery systems

An "artificial tongue" is described which can be used to calibratethe stimulus delivery characteristics of flow systems for liquidtaste stimuli. The calibrator, which functions on the basisof conductance measurements, is used to ascertain the behaviourof certain test solutions in the flow system. The test solutionsare so prepared that they mimic the hydraulic properties ofthe stimulus solutions to be used. The special apparatus requiredis neither complex nor costly, and the procedures involved arestraightforward.
