Scientists as the University of Illinois have developed a colour-changing material which, it predicts, could have architectural uses. A sheet of 1mm cells mimic the skin of an octopus and change colour through tiny variations in temperature. Professor John Rogers of the Materials Science and Engineering department said the material could be used to produce colour-changing walls or surfaces that adapt according to their preferred use. Inspired by the triple-layer skin found in cephalopods, researchers formulated a layer with a grid of 1 × 1mm photosensors that detect light pattern changes and transmit the pattern to actuators in the layer above. The technology, in its infancy, is the first step in producing a dynamic material that can vary through a number of commands.
