Co-inventors Leona Dean and Zoe Robson of London South Bank University came up with the "bright" idea for Footlume: an electroluminescent flooring solution. It's an area rug which responds to pressure with a very soft glow to help guide you to and from areas in your home in the middle of the night.
The area rug uses rechargeable batteries to generate light in response to impressions as walked upon. Although we have been unable to find the rug commercially available, in an article dated March 25 2008, the co-inventors do believe there is potentially for production.
As opposed to other light producting technologies such as photoluminescence and chemoluminescence, electroluminescence does not involve light or chemical reactions, but rather an electric field to generate the soft glowing light. An electric field passes through the material which in this case is activated by pressure.
