The static shape of drop under electrowetting actuation is well studied and recent electrowetting theory and experiments confirm that the local contact angle (microscopic angle) is unaffected while the apparent contact angle (macroscopic angle) is characterized by the Lippmann-Young equation. On the other hand, the evolution of the drop motion under electrowetting actuation has received less at...

BACKGROUND We proposed a method of using electrical stimulation for treatment of malignant melanoma through directly spray-printing liquid metal on skin as soft electrodes to deliver low intensity, intermediate frequency electric fields. METHODS With patterned conductive liquid metal components on mice skin and under assistance of a signal generator, a sine wave electrical power with voltage ...

African weakly discharging electric fish (Mormyridae) use their self-generated electric signals and electroreceptive abilities for orientation and communication in the context of courtship and territorial interactions. This paper documents socially mediated changes in the electric organ discharge (EOD) of subadult Gnathonemus petersii under non-breeding environmental conditions. Increases in EO...

Transport in a quantum point contact (QPC) can be used to generate many-body entanglement of Fermi seas in the leads. A universal relation is found between the generated entanglement entropy and the fluctuations of electric current, which is valid for any protocol of driving the QPC. This relation offers a basis for direct electric measurement of entanglement entropy. In particular, by utilizin...

Abstract Static contact angle hysteresis determines droplet stickiness on surfaces, and is widely attributed to surface roughness chemical contamination. In the latter case, defects create free-energy barriers that prevent line motion. Electrowetting studies have demonstrated similar ability of electric fields alter landscape. Yet, increase apparent static by remains unseen. Here, we report obs...

We demonstrate the use of high-frequency electric fields to guide developing axons within a 3D matrix embedded in a microfluidic device. We have used compartmentalized microfluidic chips to seed neurons and let axons grow in collagen scaffolds placed in microfluidic channels with increasing heights and with patterned electrodes on the bottom. We show that AC electric fields are capable of guidi...
