Low-energy fluidic cells could shade and cool buildings dynamically (3 minute read)
Researchers at the University of Toronto have designed a dynamic shading system inspired by the skin of krill. Krill are usually transparent, but they can move pigments around in the cells beneath their skin to turn darker and protect themselves from UV damage. The shading system is made up of optofluidic cells that can switch between transparent and opaque on demand while using relatively little energy. These cells can act as windows to provide a low-energy temperature regulation system. They could also be used to create large-scale works of art.
