Structural weight reduction and energy harvesting capabilities are the most important design criteria to significantly reduce waste energy and environmental impacts caused by fossil fuel consumption. Inspired by cellular materials, which show hierarchical microarchitectures and shape-changing properties, the objective of this research program is to introduce multifunctional metamaterials as a cutting-edge class of ultralight smart materials with tunable mechanical, hygrothermal, and electromagnetic properties. Multiscale modelling, 3D printing, and experimental characterization will be employed to develop lightweight and structurally-durable multifunctional metamaterials to achieve a high energy harvesting capability with programmable multiphysical properties for simultaneous structural, sensing, actuating, and energy harvesting applications.

减少结构重量和能源收集能力是最重要的设计标准，可显着减少化石燃料消耗造成的废物能量和环境影响。受细胞材料的启发，该材料显示出层次的微体系结构和变形的特性，该研究计划的目的是将多功能的超材料作为具有可调的机械性，流感和电磁特性的尖端的超轻智能材料引入多功能的超材料。将采用多尺度建模，3D打印和实验表征来开发轻质和可持续的多功能超材料，以实现高能量收集能力，具有可编程的多物理特性，用于同时结构，感应，感应，致命和能量收集的应用。
