This pacifier produces an "electric taste". It is not a question of sending electrical stimulations on your tongue: the Norimaki synthesizer generates a sensation of taste thanks to an electrical stimulation of gels.
This work is based on five gels which contain a conductive substance. It is this substance that makes it possible to reproduce sweet, acid, salty, bitter and umami. If the user passes his tongue over the lollipop, he will taste all tastes. "The application of different voltages to these gels causes the ions within them to move and so the quantities of different ions that touch the tongue can be controlled," the study said. In this way, the proportions of the five tastes can be adjusted, "to apply an arbitrary taste to the language of the user". In other words, by accentuating one taste or the other thanks to electrical stimulation, a flavor can be created.
Without language
"The goal is not the alteration of the taste of a meal but the transmission and reproduction of tastes at a distance", also specifies the publication. One can then imagine tasting the flavor of a product, before buying it.
What is new in this study is that there is no stimulation of the tongue: "because electricity is used only for the purpose of electrophoresis inside the gel, rather than for l 'electrocution stimulation of the tongue'.
