Foldable magnetic flux transformation for wide-area, misalignment-tolerant and interoperable wireless charging.
Article in Communications engineering, 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
In wireless power transmission, the magnetic flux cancellation caused by misalignment is the main reason for the rapid decrease, zero-crossing, and reversal of the coupling between the transmitter and receiver coils, which severely limits the effective charging area. Traditional solutions based on either compensation networks or control methods cannot break free from the constraint of low coupling. Here, we propose a foldable flux transformation technology and explain its working principle to address this issue. The receiver can adaptively and dynamically switch the direction of its own magnetic flux based on the magnetic flux of the transmitter it receives, thereby keeping the system in a state of maximum coupling. This technology breaks through the limit of misalignment tolerance, increasing the charging area by more than 100%. Furthermore, this technology enhances the interoperability of wireless power transmission systems, enabling compatibility with various mainstream coil structures.
