Over the last few decades, we've slowly gained the ability to digitally affect the human senses. First, of course, there was smell-o-vision, which releases a combination of chemicals to simulate a specific scent. With electrical stimulation of our nerves, we can simulate the sensation of touch. In the last few years, we've seen retinal implants that let digital circuitry directly interface with the optic nerve, creating the sensation of sight. For some reason, though, the one sense that we haven't electronically manipulated is taste. Now, thanks to a new electrode developed by the National University of Singapore, that might soon change.
