Wasabi-scented Smoke Alarm for the Deaf

February 20, 2010

Here’s a Japanese product that initially sounds weird but actually makes a lot of sense: a smoke alarm for the deaf with an alert that’s based on smell.

When this alarm senses smoke it emits allyl isothiocyanate, the chemical compound that powers horseradish, mustard, and wasabi.

Certainly sounds like a good way to get someone’s attention quickly, as anyone who has overindulged in H, M, or W will agree. But wait, there’s more! This scent alarm will even rouse people from sleep!

This new alarm was co-developed by Kobe-based fire extinguisher company Air Water Safety Service and Seems, a bioventure in Tokyo. For the complete story on CNET, go here.
