Abstract

Flow-controlled shape-morphing structures with multiple stable end-states

Deployable structures that significantly alter their shape and volume are used for a wide variety of applications ranging from emergency shelters to space exploration. We present an approach for realizing a long-sought-after goal of structures that can deploy onto multiple stable complex 3D surfaces. To achieve this, we utilize director-field theory to model and design the deployment process of inflatable multistable structures. In order to fabricate such deployable structures, we use multistable straw-like elements, interconnected by rigid links. The use of viscous fluid actuation allows us to not only achieve controllable and predictable deployment but also to obtain a wide variety of deployed configurations through a series of inflations and deflations of the structure while requiring only a single input
