Quirky International News: Sushi Smelling Smoke Detector!
Feb 3, 2010
Scientists in Japan have created a smoke detector for deaf
people which warns them with the smell of wasabi.
Boffins from Shiga University of Medical Science say they needed to
come up with a way of waking deaf people if they were asleep.
The problem was that 50 percent of fire victims in Japan are
elderly and often have poor hearing - meaning ringing alarms don't
wake them.
Professor Makoto Imai's design uses a synthesised version of wasabi
which is sprayed into the air created the pungent odour.
This is said to wake most sleeping people within two and a half
minutes… and give them a uncontrollable craving for sushi.
