Acoustic sensing with lightOptical acoustic sensors have gained interest for use in photoacoustic imaging systems, but can they dethrone conventional piezoelectric sensors altogether?doi:10.1038/s41566-021-00804-zDavid C. GarrettLihong V. WangNature Photonics...
In short, WGAS has capability for monitoring probe-sample shear-force interactions via remote acoustic sensing means. In another application, WGAS can also be used as feedback control of the probe's vertical position in SPM. In effect, it is observed that when the microscope's probe stylus ...
Performance Comparison of Signal Coding Method in Acoustic Sensing for Occlusion Area Using Super-directional Sound Source For sensing technology, various kinds of signals such as light, radio waves, sound waves, and lasers are used. In this study, we focused on acoustic sensin... S Koyama,O ...
This paper introduces the concept of using acoustic sensing over the radial artery to extract cardiac parameters for continuous vital sign monitoring. It proposes a novel measurement principle that allows detection of the heart sounds together with the pulse wave, an attribute not possible with existin...

Brillouin scattering in optical fibres is a fundamental interaction between light and sound with important implications ranging from optical sensors to slow and fast light. In usual optical fibres, light both excites and feels shear and longitudinal bulk elastic waves, giving rise to forward-guided a...
In addition, the least squares model indicated a very simple relationship between the two signals: the sound pressure predictions were proportional to the time derivative of the light signal samples. This relationship was explained by physical an... 展开 ...
thus taking us a step towards closing the performance gap with dolphins who are able to discriminate the same targets. This technology can be used for improved acoustic imaging, especially in underwater environments where sound is an ideal sensing medium— sound waves travel longer distances in sea...
The Bayesian analysis of macroevolutionary mixtures (BAMM)39on our larger data set found three episodes of rate shift along the phylogeny of Orthoptera (Fig.5). The first episode of rate shift took place in the common ancestor of Tettigoniidae, during the Cretaceous, with a mean clade-specif...
