Scented Fire Alarm for the Deaf

In Japan they are trying to develop a fire alarm for the deaf which will use the sense of smell, Wasabi or Japanese Horseradish will be used as it has a particularly pungent smell.

It has been said that the aroma that wasabi gives off is enough to wake the dead and when tested 13 out of 14 test subject were awoken within 2 minutes. One of the subjects who were actually deaf woke up within 10 seconds.

I think that this is a fantastic idea; a lot of the devices which are out at the moment involve flashing lights or pads to be placed under a pillow which vibrate. A lot of people sleep under their bed covers so therefore wouldn’t see the flashing lights.
