Nonlocal Conduction in a Metawire

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A 1D metawire composed of twisted copper wires is designed and realized. This metamaterial exhibits pronounced effects of nonlocal electric conduction according to Ohm's law. The current at one location not only depends on the electric field at that location but also on other locations.

Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

open access: yesAdvanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal

open access: yesAdvanced Materials, EarlyView.
Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).
