Electroluminescent Clothing - light yourself up!
EL reflective jacket
Industrial design companies PDD and Goose Design have teamed up to create a working prototype of a jacket with integrated lighting front and rear. The jacket uses a fabric made from yarns coated with Electroluminescent (EL) ink, and the lighting elements - which are almost invisible when turned off - are powered by a thin film battery and operated using a flexible switch built in to the jacket. The whole thing is washable, lightweight and flexible. EL jackets score over Fluorescent and reflective materials because they don't require a light source to be visible. Reflectives are great in the dark when cars have their headlights on, but have a blind spot around dusk when the light is failing. Obviously the system is a lot more complex, and would be expensive to produce compared to cheap reflectives, but it's certainly intersting that EL technology has come far enough for the jacket to be a viable product.
