Taste Simulator Lets You Relish Virtual Food
"A team of researchers led by Nimesha Ranasinghe at the National University of Singapore have developed a digital simulator capable of transmitting the taste of virtual food and drink to the tongue...
The device consists of a small silver electrode attached to the tip of the tongue. By slightly alternating the current and temperature of the semiconductor, taste receptors can be fooled by signals that replicate the four major tastes: salty, sweet, sour and bitter."
