Corona discharge generates an electrohydrodynamic (EHD) flow and a reactive thrust between electrodes in the air. Although theory for this two has been thoroughly developed, mechanism responsible forces acting on electrode surfaces is not well understood. Here, we numerically experimentally investigate these charges that generate them. The results show emitter collector surface deviate from equ...

Serial passage through the brains of newborn mice markedly attenuates the New Jersey strain of EHD virus. Deer inoculated with this attenuated virus show no clinical evidence of illness, but do develop virus-neutralizing antibodies in their sera. They also become solidly immune to infection with the regularly fatal unattenuated virus.

In this work, we investigate microscale electrohydrodynamic (EHD) conduction pumps of dielectric liquids in a wide working regime range from the Ohmic to saturation regime. We show that electric force EHD differs macroscale owing scale effect. reveal effect is triggered by enhanced ionic diffusion. When characteristic length system reduces millimeter micrometer, maximum order magnitude α increa...

Piezoelectricity based energy harvesting from mechanical vibrations has attracted extensive attention for its potential application in powering wireless mobile electronics recently. Here, a patterned electrohydrodynamic (EHD) pulling technology was proposed to fabricate a new self-connected, piezoelectric fiber array vertically integrated P(VDF-TrFE) nanogenerator, with a molecular poling orien...

Electro hydro dynamic (EHD) and electrostatic propulsion devices were developed in the 1920s by Thomas Townsend Brown. One such device, called a “lifter”, has no moving parts and, in the air, operates on electrical energy. It is a fashionable device and has a very simple structure, basically consisting of a narrow wire electrode and a large, flat one. However, it has a low ratio of propulsion f...

This study demonstrates for the first time abnormal electro-optic (EO) characteristics induced by electrohydrodynamics (EHD) in a polymer-dispersed liquid crystal (PDLC) film in the presence of a low-frequency (1 kHz) AC voltage. Large LC droplets (20−40 μm) buried in the film can be obtained after the illumination of one UV light with a weak intensity (~0.96 mW/cm2) for 12 h. This film exhibit...

The demand of cost-effective fabrication printed flexible transistors has dramatically increased in recent years due to the need for interface devices various application including e-skins, wearables, and medical patches. In this study, electrohydrodynamic (EHD) printing processes are developed fabricate all components polymer-based organic thin film (OTFTs), source/drain gate electrodes, semic...

Abstract We show that the spatio-temporal electrohydrodynamic (EHD) force production in surface alternative current-dielectric barrier discharge (AC-DBD) actuators is strongly influenced by both streamer regime during positive phase and micro-discharge negative phase. Focusing on spatial EHD profiles, we demonstrate ionic wind distribution can only be explained contribution of regime. The locat...

The motion of an object within a viscous fluid and in the vicinity soft surface induces hydrodynamic stress field that deforms latter, thus modifying boundary conditions flow. This results elastohydrodynamic (EHD) interactions experienced by particle. Here, we derive soft-lubrication model, order to compute all forces torque applied on rigid sphere is free translate rotate near elastic wall. We...
