Abstract: Drawing a flat map of the Earth is fundamentally challenging as continents unavoidably end up distorted. Reciprocally, complex natural shapes such as the delicate shape of Orchidea petals emanate from differential growth. From an engineering point of view, similar shape changes can be obtained when flat patches embedded with a network of channels are inflated. We will discuss different strategies involving stretchable elastomers or, conversely, stiff fabrics. Can we program the resulting 3D shapes? How robust are such inflated structures?

Biography: José Bico is associate professor at ESPCI where he teaches Fluids and Solids Mechanics. He leads with his colleagues Benoît Roman and Étienne Reyssat the MecaWet group at the PMMH laboratory. "Table top” experimentalist, his research activities range from interfacial hydrodynamics to slender structures Mechanics. Very active in science diffusion, he co-authored with his colleagues Étienne, Benoît and Étienne Guyon, “Hidden wonders”, MIT Press 2021.
