Analytical Analysis of Flexible Microfluidic Based Pressure Sensor Based on Triple-Channel Design

Emitter: International Journal of Engineering Technology, 2023
In designing a flexible microfluidic-based pressure sensor, the microchannel plays an important role in maximizing the sensor's performance. Similarly, the material used for the sensor's membrane is crucial in achieving optimal performance.

Optofluidic microchannels in aerogel [PDF]

Optics Letters, 2011
We report optofluidic waveguides made by filling microchannels in aerogel with water. The aerogel cladding is a nanoporous material with an extremely low refractive index of ~1.05, giving a large index step from the water core. Channels were formed by removing embedded optical fibers, which could be nonuniform or multiple.

Flow Direction-Dependent Elastic Instability in a Symmetry-Breaking Microchannel

Micromachines, 2021
This paper reports flow direction-dependent elastic instability in a symmetry-breaking microchannel. The microchannel consisted of a square chamber and a nozzle structure. A viscoelastic polyacrylamide solution was used for the instability demonstration.

Microchannels as Axonal Amplifiers

IEEE Transactions on Biomedical Engineering, 2008
An implantable neural interface capable of reliable long-term high-resolution recording from peripheral nerves has yet to be developed. Device design is challenging because extracellular axonal signals are very small, decay rapidly with distance from the axon, and in myelinated fibres are concentrated close to nodes of Ranvier, which are around 1 mum ...

Mechanism for clogging of microchannels [PDF]

Physical Review E, 2006
We investigate clogging of microchannels at the single-pore level using microfluidic devices as model porous media. The process of clogging is studied at low volume fractions and high flow rates, a technologically important regime. We show that clogging is independent of particle flow rate and volume fraction, indicating that collective effects do not ...

Population genetics in microchannels

Proceedings of the National Academy of Sciences, 2022
Significance Many microbial populations proliferate in small channels. In such environments, reproducing cells organize in parallel lanes. Reproducing cells shift these lanes, potentially expelling other cells from the channel. In this paper, we combine theory and experiments to understand how these dynamics affects the diversity
