A Signal Generation System for Galvanic Taste Modulation using ATmega328p Microcontroller

Galvanic taste modulation is the practice of altering the sensation of taste using electrical stimuli of a low magnitude. This research study describes the procedure of building a signal generator that specifically targets low-power signal generation for application over an individual’s buccal peripheries. Using this custom system, it would be feasible to study the correlation between taste profile and wave shape of the continuous electro stimulus. Additionally, it would also be possible to cross-quantize the stimulus of taste using VI units. Upon implementation of this technology within the domain of Augmented Reality and biomedical systems, the use cases include dietary salt reduction, experimental treatment of Ageusia etc. If explored in depth, galvanic taste modulation could essentially extrapolate itself into a subdomain of food technology as an electroculinary extension.
