Hydrogels with flavor are administered in the mouth through a small tube

The electronic language such as cake and fish soup can help to recreate food Virtual realityBut it is not possible to simulate other things that causes flavor, such as smell.
Yizhen Jia At Ohio State University and his colleagues have developed a system, called an e-taxa, how they can taste a food and can regenerate his taste in someone’s mouth.
It is the use of chemicals that match the five basic tastes: salty sodium chloride, salt acid, sweet glucose, magnesium chloride humami. “It’s already a very big spectrum of food we have every day,” says Jia.
SYSTEMS Sensors make these products to perceive these products, and then send these values to pump, which pushes hydrogels in different tips under a small tube of a person.
First, the researchers tested the systems for a single flavor, asking how to play a device at a five-point scale, compared to samples of sour taste. They gave the same number to 70 percent of the time and play real sourness.
The team then tested whether the system may have more complex tastes, lemonade, pie, fried egg, fish soup and coffee – and six people asked them to find more than 80 percent of time.
However, only focusing on such flavors is not very useful, he says Alan Chalmers At the University of Warwick, the United Kingdom, as other senses are also tasted. “Next time you have a strawberry, close your nose and eyes. It’s a very sour strawberry, but because it is smelling, because it’s sour of the smell and color, you will never know from the strawberry.
“A e-tongue like this is able to extract the amount of sweetness (and) sourness, but it does not like a human tongue as it perceives,” he said.
