Variable-Focus Liquid Lens

Variable-Focus Liquid Lens

A simulation of a variable-focus liquid lens for a miniature camera during the transition between focal lengths. The lens is made from the interface between two fluids – the lower phase velocity field is colored, the upper phase is shown by an arrow plot. The electrowetting effect is used to change the contact angle at the edge of the cylinder, creating a different meniscus radius and so modifying the focal length of the lens.

Electric Potential (left) and Fluid Streamlines and Concentration Profile (right)

Electric potential (left) and fluid streamlines and concentration profile (right), for an electroosmotic mixer during operation. Mixers are important components of lab-on-a-chip systems and the electroosmotic effect enables very small mixers to be created.

Simulation of a Semiconductor Ion Implanter

Simulation of a Semiconductor Ion Implanter

Simulation of a semiconductor ion implanter to minimize the pressure along the ion beam path using the Microfluidics Module in COMSOL. The plot shows the pressure on the surfaces of the vacuum system; two walls have been removed so that the inside of the chamber is visible.
