abstract = "We present a novel type of inflatable structure, made of three stacked membranes forming inflatable bilayers, consisting of staggered cylindrical or conical tubes. Our structures are fabricated flat using a quasi-inextensible material and bend out-of-plane when the two networks of tubular chambers are inflated to the same pressure. We program the local curvature of the structure by locally adjusting the width of the welding lines used to seal each pair of membranes.We leverage this new architected inflatable structure in an inverse design algorithm that allows us to generate inflatable ribbons of a desired target shape. Our method takes as input a developable surface, represented as a 2D polyline or a 3D quad strip, and outputs the layouts of the three membranes to be welded together. Various prototypes made of thermosealable Thermoplastic PolyUrethane (TPU) or TPU-coated nylon are fabricated to demonstrate the capabilities of our simulation approach. Inflatable bilayers present as a promising platform for shape-morphing and soft robotics applications.",
