Homei Miyashita (Meiji University) This study describes the production of a novel taste display which uses ion electrophoresis in five gels containing electrolytes that supply controlled amounts of each of the five basic tastes to apply an arbitrary taste to the user’s tongue, analogous to optical displays that produce arbitrary colors from lights of three basic colors. When applied to the tongue with no voltage, the user can taste all five tastes. However, when an electric potential is applied, the cations
