Energy consumption levels show a never-ending increase since the industrial era. Toward sustainability objectives, it is of outstanding importance to reduce amount wasted energy, that typically comes as waste heat, consequence nonunitary efficiency any thermodynamic process. Herein, breakthrough in conversion low enthalpy heat into electricity presented, based on liquid state device operates th...

Nanogenerators with capacitor structures based on piezoelectricity, pyroelectricity, triboelectricity and electrostatic induction have been extensively investigated. Although the electron flow on electrodes is well understood, the maximum efficiency-dependent structure design is not clearly known. In this paper, a clear understanding of triboelectric generators with capacitor structures is pres...

Laboratory studies, numerical simulations, and desert field tests indicate that aeolian dust transport can generate atmospheric electricity via contact electrification or “triboelectricity.” In convective structures such as dust devils and dust storms, grain stratification leads to macroscopic charge separations and gives rise to an overall electric dipole moment in the aeolian feature, similar...

The use of textile materials and structures to build textile-based TEGs is particular interest as they can also offer unique properties. In this work, the initial goal present a prototype TEG measuring device its experimental results for comparing open circuit voltages coming from various pairs knitted samples which may constitute part TEG. We focus on representing realistic testing conditions ...

New fractionation technologies are presently under investigation in order to enhance the wheat bran nutrient value. The explicit aim of the present paper was to evaluate the possibility of using the electric field forces for the separation of the fine particles generated from each wheat bran tissue during the milling process. Corona charging and surface potential decay experiments were performe...

Mechnosensational human-machine interfaces (HMIs) can greatly extend communication channels between human and external devices in a natural way. The mechnosensational HMIs based on biopotential signals have been developing slowly owing to the low signal-to-noise ratio and poor stability. In eye motions, the corneal-retinal potential caused by hyperpolarization and depolarization is very weak. H...
