Digital taste interface

Abstract

Thus far, most of the systems for generating taste sensations are based on blending several chemicals respectively, and there were no definite strategies to stimulate the sense of taste digitally. In this paper, a method for digitally actuating the sense of taste is introduced by actuating the tongue through electrical and thermal stimulations. The digital taste interface, a control system, is developed to stimulate the taste sensations digitally on the tongue. The effect of most persuading factors such as current, frequency, and temperature have been accounted for stimulating the tongue noninvasively. The experimental results suggested that sourness and saltiness are the main sensations that could be evoked while there are evidences of sweet and bitter sensations too. © is held by the owner/author(s).
