Deformation patterns and coordination mechanisms of cross-size microchannels during thermocompression bonding process

open access: yesJournal of Materials Research and Technology, 2023
High-quality bonding of microfluidic chips is essential for driving the rapid marketization of microfluidic devices. While thermocompression bonding is known for its simplicity, challenges such as high deformation and low bond strength persist.

Optofluidic microchannels in aerogel [PDF]

open access: yesOptics 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

open access: yesMicromachines, 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

open access: yesIEEE 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 ...

Effect of viscosities of dispersed and continuous phases in microchannel oil-in-water emulsification [PDF]

open access: yes, 2010
Although many aspects of microchannel emulsification have been covered in literature, one major uncharted area is the effect of viscosity of both phases on droplet size in the stable droplet generation regime. It is expected that for droplet formation to
