Pinterest is a great resource for sharing recipes and photos of your delicious creations, but it misses out on the essential sense that is taste. Well, the days of simply looking at a cake and wondering what it tastes like could be coming to an end thanks to a taste simulator that lets you sample virtual food.
The electrode can produce the taste of salty, sweet, bitter and sour food, which may mean that staring longingly at photos of food may be a thing of the past soon. The signals that reproduce the four taste components are transmitted through a silver electrode touching the tip of the tongue. A person's taste receptors are then fooled thanks to a varying alternating current and slight changes in temperature, which are controlled by semiconductor elements that heat and cool rapidly.
The team leader at the National University of Singapore, Nimesha Ranasinghe, believes that this could be used in health care and thinks that TV viewers will be able to taste the food in cookery shows as well. Time to skip to the "Here's one we prepared earlier" section.
