I believe no one will like the bitter taste of herbal tea, but when we drink herbal tea and feel the taste of ice cream on our tongues, wouldn’t it feel wonderful? Researchers at the National University of Singapore recently developed this taste simulator, which places special electrodes on the tongue to simulate the sour, sweet, bitter, and spicy tastes that feel real by inducing subtle changes in current and temperature. However, the product is still in the research and development stage and cannot yet imitate the taste of real food, but the day when it will revolutionize the taste of the tongue is not far away.
