Electronic taste stimulation

Aiming for the creation and development of taste media, a taste display was developed in this study that can reproduce tastes measured using taste sensors. By performing iontophoresis on five gels, which contain dissolved electrolytes that reproduce the five basic tastes, the quantity of ions that contact the tongue was controlled. A tasteless gel was added, so that the sum of the currents flowing in the six gels could be kept constant, ensuring a uniform amount of stimulation on the tongue. The measured tastes could be successfully reproduced through calibration, in which the indicated taste levels were matched with the taste-sensor measurements. Furthermore, video-editing software was adapted to edit taste information as well as recorded audio and video. In addition, effector and equalizer prototypes were built that can not only reproduce the recorded tastes in their original states but also adjust the tastes to match individual preferences.

“…In addition, some researchers have used this phenomenon to affect taste. Nakamura et al devised systems to impart electric taste and proposed some applications [3], and Ranasinghee et al proposed a system to control sourness and some tastes using electric current and temperature [4]. However, they did not focus on the effects of cathodal current.…”

“…It can also be used in evaluation experiments to support surgery [14]. Furthermore, Ranasinghe et al proposed a system that could digitally stimulate the sense of taste (gustation) in humans using an electric taste stimulus [15], namely, a device that attaches two electrodes to the tongue. In these studies, an electrode was attached directly to the tongue to present an electric taste stimulus; in contrast, we added electric taste stimuli to food and drink via a utensil or cup.…”

In this study, we evaluate the taste intensity of food when a saltiness enhancer is applied, for verifying the effectiveness of our system. In a previous study, we proposed a saltiness enhancer using a cathodal current based on the work of Hettinger et al. However, we received feedback from subjects that other tastes (e.g., sourness and bitterness) are also enhanced. Therefore, we conducted experimental tests to compare the intensity of the fundamental tastes and a metallic taste over three phases: before application of current, during application of current, and after the release of current.
