Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

open access: yesAdvanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

3D Printed Meter‐Scale Soft Origami Robots Capable of Load‐Bearing Actuation Via Crease Stiffness Modulation

open access: yesAdvanced Science, EarlyView.
Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.

Damage‐Free Passivation of Ambipolar OECTs with Fluoropolymer Film for Enhanced Performance and Stability Toward Reliable Biosignal Processing

open access: yesAdvanced Science, EarlyView.
A damage‐free iCVD fluoropolymer passivation strategy is introduced for ambipolar vertical OECTs. Vapor‐phase infiltration and thermal annealing induce nanoscale phase separation in the OMIEC channel, enhancing overall device performance. A single‐channel bipolar event‐driven spiking encoder is also demonstrated for electrocardiogram signal encoding ...

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 ...
