Abstract:  In recent years, the concept of mechanical metastructures developed based on nature-inspired synergistic modular architectures has been explored. For example, some of skeletal muscle’s intriguing macroscale functionalities result from the assembly of nanoscale, cross-bridge constituents that maintain multiple metastable configurations. Inspired by these observations, recent studies investigated an idea of creating modular structures from the assembly of metastable mechanical or electrical modules, and demonstrated that such metastructures would yield valuable adaptivity, including reconfiguration of global topology, orders of magnitude change in stiffness, and tunable damping and wave propagation characteristics. In another example, inspired by the physics behind the rapid plant movements and the rich designs of origami folding, a class of multifunctional metastructure is created through exploring the innovation of origami cell-based systems, which can achieve actuation & morphing, programmable & recoverable energy absorption, and tunable acoustics & dynamics. These unique characteristics are realized utilizing ideas and features such as fluidic-origami, self-locking, multistability, and lattice symmetry transformation in origami modular metastructures. This presentation will highlight some of these interdisciplinary research advances in nature-inspired multifunctional adaptive metastructures.
