<div>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 in the gel move to the cathode side and away from the tongue,
so that the flavor is tasted weakly. In this way, we have developed a
taste display that reproduces an arbitrary taste by individually
suppressing the sensation of each of the five basic tastes (like
subtractive synthesis.) Our study differs from previous work in that
it uses an electric current for electrophoresis rather than
electrically stimulating the tongue, and it does not involve ingestion
of a solution to deliver the taste.<br>
