Floating droplet electricity generator on water.
Article in National science review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hydrovoltaic technology holds great potential for energy harvesting from the natural water cycle. In this work, we present a novel water-integrated floating droplet electricity generator adopting a top electrode-dielectric-water architecture, where natural water acts as both the bottom electrode and substrate. The generator achieves high electrical output, comparable to the conventional counterpart using a metal bottom electrode and rigid substrate, while demonstrating 87% material weight reduction and 50% cost saving, as well as great durability in varying working environments. Its operational principle leverages the incompressibility and high surface tension of water to support the dielectric layer under droplet impinging and spreading, and the ion-rich composition of water enables exceptional high-frequency conductivity as the bottom electrode. The high surface tension of water also realizes unidirectional water transport for self-regulated water drainage. The advantages of water integration are further substantiated by the outstanding scalability, which is manifested by a sub-square-meter integrated device (∼0.3 m
