A team of
researchers led by a Sri Lankan origin scientist Nimesha Ranasinghe have now
developed a special electrode which can replicate sweet
bitter and sour tastes when placed on the tongue. This new marvelous discovery
doesn't just limit itself to producing sensations of taste-it also introduces
small changes in temperature to modify and enhance the taste experiences of the

is a technology for digitally simulating the sensation of taste," Dr Ranasinghe
explained. "It uses two methods-electrical stimulation and thermal stimulation
to stimulate the tip of the human tongue
non-invasively in order to produce primary taste sensations such as salty,
sour, sweet, bitter."

in an interactive system is unrealistic since a set of chemicals is difficult
to store and manipulate. Furthermore, the chemical simulation of taste is
analogous in nature, making it impractical to use this approach for digital
interactions," Dr Ranasinghe added. "Therefore, it is evident that a new
non-chemical approach is required to achieve digital control over the sensation of taste
adding the fifth taste, the savoury "umami" tang, the researchers will also be
focusing on digitally replicating the smell and texture effects to make the
"taste TV" experience wholesome.
So will this new
technology move beyond tasting and help individuals get healthier? Yes, it
