Abstract Droplet‐based electricity generators (DEGs) harness liquid‐solid electrification to convert water droplets impacts into electrical energy. This study systematically examines how droplet height, volume, flow rate, and substrate tilt angle influence DEG performance using polytetrafluoroethylene (PTFE) as a triboelectric layer deionized water. Three electrode designs (double, top, bottom) are evaluated, revealing that the double‐electrode configuration delivers highest output. enhanced arises from synergistic motion, double‐layer formation, charge discharge, validated by an equivalent circuit model. By varying heights 1–20 cm, volumes of 7.7–50 µL, rates 50–300 drops/min, angles 0–90°, optimized setup yields −70 V 22 mA, translating power density 0.28 µW cm −2 . High‐speed imaging correlates these outputs with impact dynamics resulting transfer. Additionally, can small electronic devices, capacitors, monitor artificial acid rain in real‐time, displaying distinct signals compared typical rainwater. These findings underscore potential DEGs renewable energy harvesters smart environmental sensors, paving way for advanced on‐demand generation diverse settings.

Interfaces between a liquid and solid (L-S) are the most important surface science in chemistry, catalysis, energy, even biology. Formation of an electric double layer (EDL) at L-S interface has been attributed due to adsorption ions surface, which causes redistribute. Although existence charges on is always assumed, origin not extensively explored. Recent studies contact electrification (CE) suggest that electron transfer plays dominant role initial stage for forming charge interface. Here, we review recent works about liquid-solid CE, including scenerios such as liquid-insulator, liquid-semiconductor, liquid-metal. EDL revisited considering Furthermore, triboelectric nanogenerator (TENG) technique based CE introduced, can be used only harvesting mechanical energy from but also probe probing interfaces.

Mechanochemistry has been studied for some time, but research on the reactivity of charges exchanged by contact-electrification (CE) during mechanical stimulation remains scarce. Here, we demonstrate that electrons transferred CE between pristine dielectric powders and water can be utilized to directly catalyze reactions without use conventional catalysts. Specifically, frequent at Fluorinated Ethylene Propylene (FEP) - interface induces electron-exchanges, thus forming reactive oxygen species degradation an aqueous methyl orange solution.

Abstract The past several years have witnessed the rapid development in effectively transforming randomly distributed water kinetic energy into electrical energy, especially triggered by emergence of droplet‐based electricity generators (DEG). Despite this, it still suffers from relatively low average power density, which is also achieved at cost long charging time, time to reach stable and saturated surface charge density either through continuous droplet impingement or precharging. Although harvested per DEG remains as dominant metric, ultrahigh instantaneous output short are equally important some specialized applications such luminescence. Here, we conduct systematical modeling optimization build link between hydrodynamic systems, enables us determine tailoring parameters dielectric layer thickness, ion concentration, external load. We envision that this strategy achieving well shortening would provide insights design routes for harvesting.
