Bio-lighting Sign / Sign Board

Bio-lighting Sign

There are countless safety Exit signs all over the world.They consume a lot of electricity every day, but they will be used in very few cases.

Vibrio-Fischeri is a common bacterium in the ocean. They can be easily cultured on agar. When they get together, they produce green fluorescence, which is the same color as most exit signs.
We have designed a kind of sign board which uses the luminescent characteristics of Vibrio-F
ischeri. These signs can shine continuously without electricity.

And we designed different signs that can be replaced to meet various use scenarios for the sustainable cities.
