Piezoelectric MEMS vibration energy harvester using BiFeO
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Resonant-type piezoelectric vibration energy harvesters (pVEHs) can achieve high energy conversion efficiency and output power density by using resonance phenomena with external vibrations at constant frequencies. However, this approach is less effective for the random vibrations commonly encountered in real-world environments, thus limiting its practical applications. This study employs impulsive forces and a two-degree-of-freedom system with a dynamic magnifier (DM) to enhance the output power of a nonresonant microelectromechanical systems-based pVEH (MEMS-pVEH).
