Digital Lollipop (Electric lollipop) utilizes electrical stimulation on the human tongue to simulate different taste sensations. At present, the system is capable of manipulating the properties of electric currents (magnitude, frequency, and polarity: inverse current) to formulate different stimuli. Currently, we are conducting experiments to analyze regional differences of the human tongue for electrical stimulation.

Stay tuned for more information in the future....
