Developing a technology that can share tastes without the risk of infection: Prof. Homei Miyashita has developed a taste display that expresses an arbitrary taste
May 27, 2020
The Miyashita Laboratory has been working on electric taste, a taste sensation generated by electric stimulation to the tongue. The laboratory’s inventions using this technology include a chewing gum that creates a taste with power generated by the chewing movement  and a method that enhances and prolongs the aftertaste of a drink. Taking advantage of this technology, Dr. Miyashita’s lab is also conducting a project aimed at enhancing the taste of healthy food without chemical augmentation. This taste display, however, does not involve tongue electrostimulation. The aim is not the alteration of the taste of a meal but the remote transmission and reproduction of tastes.
The paper on Norimaki Synthesizer, a prototype of this experimental taste display is now available at the following URL. Prof. Miyashita is working on ways to make taste more reproducible and representable than shown in this paper.
