Liquid metals, with their unique combination of electrical and mechanical properties, offer
great opportunities for actuation based on surface tension modulation. Thanks to the scaling …

Digital microfluidics (DMF) is an emerging liquid-handling technology that enables
individual control over droplets on an open array of electrodes. These picoliter-to microliter …

This paper reviews publications that have fortified our understanding of the electrowetting-
on-dielectric (EWOD) actuation mechanism. Over the last decade, growing interest in EWOD …

Wearable sweat sensors can analyze the abundant composition of solutes and metabolites
in sweat to reflect the health state of the wearers in real time. The realization of active motion …

We introduce DropBot: an open-source instrument for digital microfluidics
(http://microfluidics. utoronto. ca/dropbot). DropBot features two key functionalities for digital …

More than one century ago, Lippmann found that capillary forces can be effectively
controlled by external electrostatic forces. As a simple example, by applying a voltage …

In digital microfluidics, droplet generation is a fundamental operation for quantitative liquid
manipulation. The generation of well-defined micro-droplets on a chip with restricted device …

Conventional electrowetting displays reconfigure the contact angle of a coloured oil film on a
planar hydrophobic surface. We report on electrofluidic displays, in particular a three …

Flow boiling in microchannels has received considerable attention from researchers
worldwide in the last decade. A scaling analysis is presented to identify the relative effects of …

Extensional flows and the underlying stability/instability mechanisms are of extreme
relevance to the efficient operation of inkjet printing, coating processes and drug delivery …
