Efficient Cholesteric Liquid Crystal Waveguide Polarizing Splitters for High‐Sensitivity Chip‐Scale Atomic Magnetometry

open access: yesAdvanced Science, EarlyView.
An integrated polarimetry architecture based on a cholesteric liquid crystal waveguide polarization splitter overcomes the volumetric bottleneck in chip‐scale atomic magnetometers. By leveraging Bragg‐selective reflection and total‐internal‐reflection‐induced helicity inversion, this ultrathin device enables efficient circular polarization splitting ...

Imperfect Oriented Attachment of Gold Nanoparticles

open access: yesAdvanced Science, EarlyView.
The cover illustrates the imperfect oriented attachment of gold nanoparticles in liquid, as revealed by in situ liquid‐phase transmission electron microscopy. Triggered by the abrupt collapse of the interfacial hydration layer, two misoriented nanoparticles undergo a kinetically driven “jump‐to‐coalescence”.

A Modular Variable Stiffness Co‐Bot System Achieving Tasks Flexibility and Contact Compliance

open access: yesAdvanced Science, EarlyView.
Bio‐inspired antagonistic compliance enables a modular rigid‐soft co‐bot platform with variable stiffness for safe human‐robot interaction (HRI): Standardized interfaces support application‐driven configurations with tailored DoFs, workspace, and stiffness range, making the system suited to HRI and low‐volume automation.

A Reconfigurable Memristive Spiking Neuron Enabling Advanced Neuromorphic Computing

open access: yesAdvanced Science, EarlyView.
Pek Jun Tiw and co‐workers develop a reconfigurable memristive neuron that can exhibit four spiking behaviors with freely tunable spike train parameters. The neuron supports multiplexed spike encoding of multiple pieces of information. It also supports advanced neural network strategies, such as neural heterogeneity and dynamic mode switching ...

A Thickness‐Invariant Origami Robot With Integrated Actuation and Multimodal Locomotion

open access: yesAdvanced Science, EarlyView.
A thickness‐invariant variation on the Yoshimura origami pattern is used as the basis of a robot, allowing power, actuation, and control systems to be embedded within the thickened panels of the pattern. The robot uses multiple kinematic branches to achieve distinct modes of locomotion, such as walking, running, galloping, and turning. ABSTRACT Origami
