Microfluidics: Fluid physics at the nanoliter scale [PDF]
, 2005 Microfabricated integrated circuits revolutionized computation by vastly reducing the space, labor, and time required for calculations. Microfluidic systems hold similar promise for the large-scale automation of chemistry and biology, suggesting the ...

Accelerated electrowetting-based tunable fluidic lenses.
Optics Express, 2021 One of the limitations in the application of electrowetting-based tunable fluidic lenses is their slow response time. We consider here two approaches for enhancing the response speed of tunable fluidic lenses: optimization of the properties of the fluids

Actuation of Flexible Membranes via Capillary Force: Single-Active-Surface Experiments
Micromachines, 2018 Conventional approaches to microscale actuation, such as electrostatic, have difficulty in achieving large motion at moderate voltages. Recently, actuators relying on the active control of capillary pressure have been demonstrated, with the pressure ...

Density functional theory of electrowetting
, 2014 The phenomenon of electrowetting, i.e., the dependence of the macroscopic contact angle of a fluid on the electrostatic potential of the substrate, is analyzed in terms of the density functional theory of wetting.

Electrowetting of a nano-suspension on a soft solid
, 2018 The wetting of solid surfaces can be manoeuvred by altering the energy balance at the interfacial region. While electric field acts favourably to spread a droplet on a rigid surface, this tendency may be significantly suppressed over soft surfaces ...

Deformation of a nearly hemispherical conducting drop due to an electric field: theory and experiment [PDF]
, 2014 We consider, both theoretically and experimentally, the deformation due to an electric field of a pinned nearly-hemispherical static sessile drop of an ionic fluid with a high conductivity resting on the lower substrate of a parallel plate capacitor ...

Droplet Microfluidics for Chip-Based Diagnostics
Sensors, 2014 Droplet microfluidics (DMF) is a fluidic handling technology that enables precision control over dispensing and subsequent manipulation of droplets in the volume range of microliters to picoliters, on a micro-fabricated device.

Actuating droplets with electrowetting: Force and dynamics
DropletElectrowetting on dielectric (EWOD) allows rapid movement of liquid droplets on a smooth surface, with applications ranging from lab‐on‐chip devices to micro‐actuators. The in‐plane force on a droplet is a key indicator of EWOD performance.

Wetting of Flat Gradient Surfaces
, 2018 Gradient, chemically modified, flat surfaces enable directed transport of droplets. Calculation of apparent contact angles inherent for gradient surfaces is challenging even for atomically flat ones.

Tuneable plasmonics enabled by capillary oscillations of liquid-metal nanodroplets [PDF]
, 2017 Plasmonics allows manipulating light at the nanoscale, but has limitations due to the static nature of nanostructures and lack of tuneability. We propose and theoretically analyse a room-temperature liquid-metal nanodroplet that changes its shape, and ...
