  booktitle={CEA '13},
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…

Mechanism of inhibitory effect of cathodal current tongue stimulation on five basic tastes
By focusing on the electrophoresis of ions generated by dissolution of taste-inducing substances in water, this paper indicates how human gustation is inhibited by electrical stimulation, which is a key addition to the knowledgebase for achieving control of all five basic tastes.
Anodal Galvanic Taste Stimulation to the Chin Enhances Salty Taste of NaCl Water Solution
Anodal GTS is effective in enhancing the salty taste of NaCl aqueous solutions, and the perceived intensity increased as the current intensity applied to the chin increased.
Design of Electrical Stimulation Waveform for Enhancing Saltiness and Experiment on Low-Sodium Dieters
Electric tastes can present various taste modulation effects using stimulation waveforms. Presenting and stopping cathodal stimulation or presenting anodal stimulation, for example, can enhance the
Controlling Temporal Change of a Beverage's Taste Using Electrical Stimulation
This paper focused on the taste before and after swallowing as a first step and proposed the concept of controlling the temporal change of a beverage's taste using electrical stimulation.
Unlimited Electric Gum: A Piezo-based Electric Taste Apparatus Activated by Chewing
"unlimited electric gum," an electric taste device that will enable users to perceive taste for as long the user is chewing the gum, is proposed and experimental and exhibition results are reported.
Virtual Taste and Smell Technologies for Multisensory Internet and Virtual Reality
An electrical tongue stimulation device, which the user places in their mouth to produce taste sensations, is proposed, which shows a new user experience through digital taste stimuli.
Digital Taste in Mulsemedia Augmented Reality: Perspective on Developments and Challenges
The article explores techniques from prominent research pools with an inclination towards taste modulation and proposes feasible extensions to the already established technological architecture for taste stimulation and modulation, namely, from the Internet of Things, artificial intelligence, and machine learning.
Flexible Tongue Electrode Array System for In Vivo Mapping of Electrical Signals of Taste Sensation.
The results show that an appropriate electrical stimulation can induce multiple sensations simultaneously, while the distribution of each sensation was not significantly distinguished among different zones of the tongue, and at the same time, this taste-related electrical signal can be recorded by the FTEAS.
Metallic: A Bivalent Ambimodal Material Property?
This review assesses those sensory stimuli that people choose to refer to as metallic, summarising the multiple, often symbolic, meanings of (especially precious) metals.


Enhancing saltiness with cathodal current
This study proposes a saltiness enhancer that applies weak cathodal current for a short time when the user eats or drinks, and the user can perceive a salty taste without the use of salt.
Salt enhances flavour by suppressing bitterness
It is proposed that salts selectively filter flavours, such that unpleasant tastes are more suppressed than palatable ones (such as sweetness) thereby increasing the salience and/or intensity of the latter.
Development and evaluation of interactive system for synchronizing electric taste and visual content
The latencies for electric taste and visual stimuli are measured as a basic evaluation for a content presentation system in which electric Taste and visual content are synchronized.
Taste qualities elicited by electric stimulation of single human tongue papillae
SummarySingle human taste papillae in 5 young test subjects were electrically stimulated 84 times earch with a silver wire (0.4 mm tip diameter)versus a 5 × 3.5 cm2 reference electrode on the left
Get excess salt out of our diet
Once a commodity of exchange, salt is now a commodity of disease and death. We underestimate how much excess salt we eat and how much harm it can do. The greatest harm comes from high blood pressure
Electro-stimulation of the tongue as a passive surgical guiding system
The present work proposes to use another sensory modality to guide the surgeon thus keeping the visual modality fully dedicated to the surgical gesture, using the Bach-y-Rita's "Tongue Display Unit" (TDU) to provide to the surgeon information of the position tool.
