This fork uses electricity powered by a battery to stimulate the tongue to taste sugar and salt in food that have no added sugar or salt. By stimulating the tongue with electricity, you can add flavor to food without adding actual salt or sugar. So, now your fork does more than it ever did before. This utensil also can be used as a spoon and a knife. Current 3D printing technology allows us to print batteries and electronics as well as a plastic housing in one prototype.
