I was browsing news articles about “scent technology” and I came across one about Japanese researchers who won the lg Nobel prize last year for inventing a smoke alarm that sprays a wasabi scent. This is supposed to alert people who have a hearing disability that there is danger. Makoto Imai, and his six other teammates said at this device is a life saver. They also discovered the ideal density of airborne wasabi to awaken sleepers in crisis. They had to figure out how much they could use of the scent without it being potent but yet still awake someone who is sleeping. The scent is not very tolerable but that’s okay since it’s supposed to warn you of danger. What do you think about it? Isn’t scent incredibly powerful? The time for scent is finally arrived. And we can’t wait to lead the sciences and technologies behind it!
