Advanced Science, EarlyView.This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

Wide‐Flow Aerosol Jet Printing Enables High‐Throughput, Ultra‐Low Aspect Ratio Patterning
Advanced Science, EarlyView.Wide‐flow aerosol jet printing (WF‐AJP) employs an anisotropic nozzle design to generate planar aerosol jets, enabling millimeter‐scale deposition of highly uniform, ultra‐low aspect ratio (<1:6000) films with substantially reduced anisotropy in functional performance.

Hundred‐Nanometer‐Thick Stretchable Liquid Metal Films for Ultra‐Conformal Bioelectrodes
Advanced Science, EarlyView.A low‐temperature deposition strategy is proposed to fabricate 19 nm‐thick liquid metal nanofilms (conductivity: 3 × 10⁶ S m−1) for developing ultra‐thin, high‐conductivity epidermal electrodes. The 1 µm‐thick composite achieves 8.5 kΩ skin contact impedance and 26 dB EMG SNR, enabling robust dynamic electromyography during movement.

Advanced Science, EarlyView.Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...
