A night light in the form of a rug that lights up underfoot as you walk along it has been developed at London South Bank University in the UK. When you step on 鈥淔ootLume鈥�, pressure pads switch on electroluminescent panels beneath the fabric 鈥� giving the rug a soft glow that shuts off after 5 minutes. Co-inventor Zo毛 Robson says the next development is to make FootLume respond to music.
The smell of horseradish could soon be more than a sign of an imminent roast dinner. A smoke alarm developed at Shiga University of Medical Science Hospital in Japan exploits the fact that the pungent aroma of horseradish wakes people from the deepest sleep 鈥� especially if they are hearing impaired. The device, which will spray a horseradish extract, could be launched within two years.
