With the advent of droplet-based triboelectric nanogenerators (D-TENGs), methods for converting raindrop kinetic energy to electrical have developed rapidly. However, current D-TENG designs suffer from slow solid-liquid interface separation speeds and susceptibility liquid residues. These issues compromise output performance D-TENGs limit their applications in high-power appliances. To address this, this study presents a needle electrode nanogenerator (NED-TENG). The functions as top electrode, optimizing contacts efficiently harvesting by leveraging electrostatic induction mechanisms. This is made one end copper wire, with its other directly connected harvester. setup positions all wiring on back substrate, accelerating separation, mitigating residue formation, simplifying device fabrication. Upon assembly device, several factors influencing fabricated action mechanisms are explored improve efficiency. Experimental results reveal that designed only requires 6 s saturate surface charge polytetrafluoroethylene film, achieving short-circuit (ISC) up 4.76 mA an voltage (V0) 563 V. Overall, offers straightforward effective approach rainwater.

Abstract Opening new horizons for droplet‐based energy harvesters, electricity generators (DEGs) face several obstacles, such as deficient current output and vulnerability to the external environment. In this study, a multigenerator (DEMG) subserved by an electromagnetic generator (EMG) is proposed tackle them. By introducing mechanical buckling‐induced 3D structure, DEMG designed have sufficiently high figure of merit flexibility/elasticity harvest electric from droplets. Thanks hybrid effect EMG, total amount induced charge enhanced more than 8809% compared with that DEG only. Furthermore, continuous supply expected even under dusty humid conditions. This study not only provides pathway overcome inherent limitations conventional DEGs but also paves way efficient droplet harvesting technologies applicable in diverse environmental
