Near‐Field Acoustic Imaging Using Fiber‐Optic Distributed Acoustic Sensing and Beamforming Techniques

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

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.
