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 ...

Biomimetic 4D printing

Nature Materials, 2016
Shape-morphing systems can be found in many areas, including smart textiles, autonomous robotics, biomedical devices, drug delivery and tissue engineering. The natural analogues of such systems are exemplified by nastic plant motions, where a variety of organs such as tendrils, bracts, leaves and flowers respond to environmental stimuli (such as ...
