High‐Stress Si3N4 Reflective Membranes Monolithically Integrated With Cavity Bragg Mirrors
Advanced Optical Materials, EarlyView.Silicon nitride membranes are record‐breaking mechanical sensors, yet their delicate fabrication and alignment into precision optical cavities have confined them to the laboratory. A monolithic process directly integrates suspended high‐stress Si3N4${\rm Si}_{3}{\rm N}_4$ membranes onto Bragg mirrors, forming self‐aligned optomechanical cavities in ...

Advanced Optical Materials, EarlyView.Spherical liquid crystal polymer microlasers with a bipolar configuration confine lasing to a single equatorial plane, allowing precise control over where the laser emission is generated. The anisotropic refractive index profile additionally lifts the energy degeneracy of azimuthal whispering gallery modes, which causes a characteristic splitting into ...

Linear and Nonlinear Optical Tuning With Sb2S3‐Based Metasurfaces
Advanced Optical Materials, EarlyView.Sb2S3${\rm Sb}_2{\rm S}_3$ resonant metasurfaces provide large, reconfigurable optical modulation and tunable enhanced nonlinear emission across telecommunication wavelengths. Monolithic structures achieve 92% transmission modulation and 150 nm resonance tuning, while hybridization with silicon enables strong modulation at nearly half the switching ...

Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance
Advanced Optical Materials, EarlyView.Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing
Advanced Robotics Research, EarlyView.This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
