a device that creates five basic tastes, the intensity of which can be changed.

the Author of the invention of Japanese engineer Homei Miyashita of Meiji University presented their device at the conference CHI 2020.

Today, play sensual images for vision and hearing, and partly for the touch, and the re-creation of taste sensations scientists still working. Basically, this has been achieved through direct stimulation of the receptors of a certain type. So, you have previously created chopsticks, imitating a sour or salty taste.

the unit of Japanese scientist applied a different principle of operation, it is able to simultaneously combine all five basic tastes – salty, sour, sweet, bitter and umami. The latest release in China, Japan and other Far East countries. It creates monosodium glutamate used as seasoning, and some amino acids, that are food additives.

the Device is Homey Mesiti wrapped in copper foil up with five other tubes inside. They are gel with various taste substances: sodium chloride for salty, sweet for glycine, magnesium chloride for the bitter, citric acid for sour, and monosodium glutamate, simulating minds. The tube is connected to the current source through the rheostat to change the resistance.

When attached the ends of the tubes to the tongue, forms a closed circuit. There is the opportunity to experience all five tastes at once, and the intensity of each can be reduced. Using the device, for example, you can feel the taste of sushi, wrapping the end of the tube in nori (edible species of red algae) and adjusting the rheostats on the sour-salty taste.
