Seismic signal characterization of snow avalanches using distributed acoustic sensing in Grasdalen, western Norway [PDF]

Natural Hazards and Earth System Sciences
We show the use of distributed acoustic sensing for analyzing seismic signals from snow avalanches. For three winter seasons, we continuously recorded seismic data using distributed acoustic sensing (DAS) on a standard telecommunication fiber along a ...

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

Advanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...
