A Bioinspired Underwater Soft Robot for Active Intravesical Liquid Delivery and Mixing

Advanced Intelligent Systems, EarlyView.
A bioinspired underwater soft robot is reported that integrates an elastic strain energy‐driven soft robotic pump with a programmable flexible magnetic valve, enabling remotely controlled, programmable, and sustained liquid release and mixing. This functionality is enabled by the synergistic integration of elastic strain energy‐driven pumping and ...

Laser speckle contrast imaging in biomedical optics [PDF]

Journal of Biomedical Optics, 2010
First introduced in the 1980s, laser speckle contrast imaging is a powerful tool for full-field imaging of blood flow. Recently laser speckle contrast imaging has gained increased attention, in part due to its rapid adoption for blood flow studies in the brain. We review the underlying physics of speckle contrast imaging and discuss recent developments

Impact of velocity distribution assumption on simplified laser speckle imaging equation [PDF]

Optics Express, 2008
Since blood flow is tightly coupled to the health status of biological tissue, several instruments have been developed to monitor blood flow and perfusion dynamics. One such instrument is laser speckle imaging.

Quantitative modeling of laser speckle imaging [PDF]

Optics Letters, 2006
We have analyzed the image formation and dynamic properties in laser speckle imaging (LSI) both experimentally and with Monte-Carlo simulation. We show for the case of a liquid inclusion that the spatial resolution and the signal itself are both significantly affected by scattering from the turbid environment.

Laser speckle contrast imaging: theoretical and practical limitations [PDF]

Journal of Biomedical Optics, 2013
. When laser light illuminates a diffuse object, it produces a random interference effect known as a speckle pattern. If there is movement in the object, the speckles fluctuate in intensity.
