Electrowetting without external voltage using paint-on electrodes

LAB ON A CHIP, 17(6), 1069–1075.

By: C. Eaker n, I. Joshipura n, L. Maxwell n, J. Heikenfeld * & M. Dickey n 

topics (OpenAlex): Electrowetting and Microfluidic Technologies; Modular Robots and Swarm Intelligence; Biosensors and Analytical Detection
TL;DR: This work presents a new method to dramatically reduce the complexity of electrode and dielectric fabrication while enabling multiple performance advances and opens up new application spaces for electrowetting (e.g. stretchable substrates, soft and injectable electrodes) while achieving large changes in contact angle without the need for an external power supply.

2017 journal article

Oxidation-Mediated Fingering in Liquid Metals

PHYSICAL REVIEW LETTERS, 119(17).

By: C. Eaker n, D. Hight n, . John D. O'Regan, M. Dickey n  & K. Daniels n 

topics (OpenAlex): Adhesion, Friction, and Surface Interactions; Surface Modification and Superhydrophobicity; Nanomaterials and Printing Technologies
TL;DR: It is found that electrochemical oxidation can generate compressive interfacial forces that oppose the tensile forces at a liquid interface, which is important for the development of reconfigurable electronic, electromagnetic, and optical devices that take advantage of the metallic properties of liquid metals.

2014 journal article

Giant and switchable surface activity of liquid metal via surface oxidation

Proceedings of the National Academy of Sciences, 111(39), 14047–14051.

By: M. Khan*, C. Eaker*, E. Bowden n  & M. Dickey* 

author keywords: EGaIn; electrocapillarity; electrorheology; dewetting; spreading
topics (OpenAlex): Electrowetting and Microfluidic Technologies; Electrohydrodynamics and Fluid Dynamics; Nanomaterials and Printing Technologies
TL;DR: This work suggests that the wetting properties of surface oxides—which are ubiquitous on most metals and semiconductors—are intrinsic “surfactants” that can be harnessed to induce previously unidentified electrohydrodynamic phenomena for manipulating liquid metal alloys based on gallium.
