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...

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...

A high-resolution method to image the horizontal boundaries of gravity and magnetic sources is presented (the enhanced horizontal derivative (EHD) method). The EHD is formed by taking the horizontal derivative of a sum of vertical derivatives of increasing order. The location of EHD maxima is used to outline the source boundaries. While for gravity anomalies the method can be applied immediatel...
