Bistable Multi-Layer Triboelectric Nanogenerator for Harvesting Random and Ultra-Low-Frequency Vibration Energy with Increased Charge Transfer.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 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
Approximately 70% of the Earth's surface is covered by seawater, making the ocean ideal for harvesting energy. Triboelectric nanogenerators (TENGs), due to their low cost and simple structure, are well-suited for capturing ocean energy. However, their low charge transfer under weak inputs limits efficiency in harvesting random and ultra-low-frequency wave energy. This paper proposes a novel bistable multi-layer TENG (BM-TENG) to address this challenge for self-powered wireless sensing and lighting. Simulations and experiments demonstrate that both in intra-well and inter-well motions, the bistable mechanism enhances the dynamic responses and thus the power output by up to 48%. Furthermore, the multi-layer design within the constrained structure significantly boosts the power density. Experimental results show 730 V peak-to-peak open-circuit voltage and 5 mW maximum power in a three-layer BM-TENG under the excitation of 0.6 Hz and 0.18 g. The normalized power density of the proposed device is 54.9 Wm
