This Lickable Screen Can Recreate Almost Any Taste or Flavor Without Eating Food gizmodo.com

AdvertisementYears ago it was thought that the tongue had different regions for tasting sweet, sour, salty, and bitter flavors, where higher concentrations of taste buds tuned to specific flavors were found.
Our better understanding of how the tongue works is crucial to a new prototype device that its creator, Homei Miyashita, calls the Norimaki Synthesizer.
Miyashita wondered if a similar approach could be used to trick the tongue, which is why their Norimaki Synthesizer is also referred to as a taste display.
It’s a subtractive process that selectively removes tastes to create a specific flavor profile.
I n testing, the Norimaki Synthesizer has allowed users to experience the flavor of everything from gummy candy to sushi without having to place a single item of food in their mouths.
