Integrated Ultrasonic Platform for Bioelectronic Control through Biological Barriers Based on Metasurface

Advanced Science, EarlyView.
A metasurface‐enabled ultrasonic platform achieves precise multi‐focal control through biological barriers, real‐time physiology‐driven modulation, and simultaneous wireless power and data transmission. By unifying wavefront engineering, closed‐loop feedback, and acoustic communication, this work establishes key enabling technologies toward scalable ...

Advances in Distributed Acoustic Sensing (DAS) for VSP

SEG Technical Program Expanded Abstracts 2012, 2012
Last year we introduced Distributed Acoustic Sensing (DAS) as a new method for VSP acquisition. In DAS, an optical fiber along the borehole serves as a seismic receiver array. The fiber is interrogated by a special device at the surface, sometimes referred to as lightbox.
