Remorphable Architectures: Reprogramming Global Bistability through Locally Bistable Metamaterials

Advanced Materials, EarlyView.
Local bistable reconfiguration in mechanical metamaterials is leveraged in globally bistable architectures to enable in situ reprogrammable transition pathways through state flip of individual building blocks. The local‐to‐global correspondence of instabilities empowers soft robotic systems with on‐demand morphing traits, as well as aerospace ...
