Regardless of the technology, additive or subtractive, miniaturization trend is constantly pushing for smaller resolutions. The rise global challenges in material availability, fabrication three dimensions (3D), design flexibility and rapid prototyping have pushed manufacturing (AM) into spotlight. Addressing trend, AM has already successfully answered microscale 3D fabrication. However, fabric...

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...
