At Springwise, we have seen some innovative designs for sunshades. These have included a folded building façade and a canopy moved by drones. Now, a civil engineering doctoral student at ETH Zurich’s Institute for Building Materials has developed an adjustable shading system that can change shape throughout the day – without using any motors or sensors. Engineer Chiara Vailati developed a prototype inspired by the design of the pinecone. Vailati studied the way that pinecone scales open and close in response to changes in humidity. The scales of the pinecone consist of two connected layers that contract to different degrees…
