A research team from the University of Science and Technology of China (USTC) has put forward a design concept for electrothermal lattice metamaterials. This innovative approach allows for the simultaneous and independent programming control of electric and thermal fields via a single structural framework. The study adopts a modular design methodology, linking lattice units through bridges that exhibit high thermal and electrical conductivity. Through straightforward adjustments to the spatial arrangements and geometric configurations of these units, it becomes possible to achieve effects such as field cloaking, focusing, and rotation. This marks a significant breakthrough over the static design constraints of conventional dual-field metamaterials. The relevant research findings have been published in Advanced Materials, offering crucial technical backing for the advancement of devices operating in intricate multi-physics field settings.
