The phrase “share a drink with friends” may soon take on new meaning, thanks to research from a team at the National University of Singapore (NSU). Young scientists have learned to imitate the taste of lemonade using electrodes immersed in ordinary water. The synthesized taste can be easily transmitted wirelessly.
Unfortunately, many delicious foods are actually not always healthy. How to be in this case, so as not to harm yourself? And here it was not without modern technology. Electronic devices began to appear that mimic the tastes and smells of their favorite products without harming their health. One of them is the Edible Mist Machine, which has up to 200 tastes and aromas from chocolate to smoked bacon.
The NSU researchers took a slightly different route, using electrical stimulation of the tongue to simulate tastes, thereby mimicking what we call "sweet, " "sour, " "salty, " and "bitter."
They went even further and attempted to teleport the taste of lemonade by first creating a digital model of it, then translated into the "language" of electrical signals. The choice of lemonade is not accidental because of its bright, memorable taste.
Initially, an analogue pH sensor was placed in real lemonade, which allowed us to determine the acidity level of the drink. Another sensor recorded the RGB color of the drink. The received data was transmitted via Bluetooth to a "lemonade simulator" - a high-tech glass with LED illumination at the bottom and electrodes along the rim.
The LED reproduces the color of the original drink, while the electrodes send electrical impulses to the tongue, simulating lemonade sourness.
