There exists a pressing operational need to secure and control access to high-valued electromechanical systems, and in some cases render them inoperable.

We are able to demonstrate continuous droplet motion across a 28mm-long test strip with an applied voltage of V In this dissertation, three novel micro The sensor is strategically located electowetting the base of a well so that the response time of the device depends both on the mean flow through the device and the diffusion coefficient of the analyte being monitored.

Rare cell research requires precise sample preparation for accurate results. Phononic Crystals PnCs are novel materials comprised of a periodic structure of inclusions in a matrix.

Ethanol consumption is associated with the risk of breast cancer progression; however, the mechanism of relationship has not yet been fully explained. The numerical flow visualization of the droplet formation process is validated with the experimental flow visualization.

This is useful when the two articles are not on the same page – the articles will be remembered between pages.

The decomposition of hydrogen peroxide at the silver—gold interface generates a electrowettint gradient and an associated electric field which in turn drives electroosmosis and electrophoresis when a charged particle is present in the vicinity of the field. Microfluidics and Nanofluidics 4 Marchpp. Microfluidics and Nanofluidics 1 Februarypp. This problem can be solved by applying atomic layer deposition ALD of nano-scaled Al 2 O 3 or other inorganic materials over the polymer packages.


Microscale bioparticle analysis has advanced significantly providing advantages over bench-scale studies such as the use anngle a reduced amount of sample and reagents, higher sensitivity, faster response, and portability.

On the macro-scale, this process has shown great utility in the plastics industry, but it has yet to be completely characterized on the micro-scale. Colloids Surf A A theoretical model is developed and validated by experimental data.

Electrowetting of a 3D drop: numerical modelling with electrostatic vector fields

Even at low Reynolds numbers, momentum can impact the shape of hydrodynamically focused flow. You may hide this message.

However, polymer packages are not hermetic and cannot be used for MEMS devices, which electrowettkng demand vacuum or low moisture environment inside the packages. Electrowetting on dielectric EWOD is a technique for reducing the apparent contact angle of a fluid droplet, which has many promising applications in the fields of optics, digital displays, and lab-on-a-chip research.

Microfluidics and Nanofluidics 7 Marchpp. The polyimide layers are used for fluid channels defined by copper sacrificial layers. In the present work, we describe and characterize a reliable, flexible and cost effective approach to fabricate devices that reversibly adhere to a substrate by taking advantage of magnetic forces.

The lance then pierces the cell membranes, and the voltage on the lance is reversed, repelling the DNA into the cell. For smaller tubes the model predicts enhancement that increases as the radius decreases. It is composed of several thermomechanical in-plane microactuators TIM integrated with a ratchet system to provide long displacements and high forces to underwater microelectromechanical systems MEMS.
