Active Metamaterials and Structures
Metamaterials consist of specifically designed periodic patterns, showing tailorable mechanical, acoustic, optical, or electromagnetic properties. Reconfigurable metamaterials, also called active metamaterials, possess actively tunable patterns and/or physical properties, facilitating more versatile and programmable use.
The bilayer design strategy enables shape reconfiguration with area preservation, which can be further exploited in acoustic applications, including highly tunable bandgaps and waveguides.

We develop an inverse design framework where a deep residual network replaces the conventional finite-element analysis for acceleration, realizing metamaterials with predetermined global strains under magnetic actuations
DetailsA new magneto-mechanical metamaterial permits great shape and multi-physical property tunability through a novel concept of deformation mode branching
DetailsA mechanics-guided mechanism for multimodal deformation is demonstrated, which enables magnetically active metamaterial for tunable mechanical properties
