Highly efficient ionic actuators enabled by sliding ring molecule actuation.
Article in Nature communications, 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
Ionic actuators with capability of electro-mechanical transduction are emerging as a useful platform for artificial intelligence and modern medical instruments. However, the insufficient ion transport inside material interfaces usually leads to limited energy transduction efficiency and energy density of actuators. Here, we report a polyrotaxane interface with adjustable ion transport based on sliding-ring effect for highly-efficient ionic actuators. The switch status of ion channels is synchronous with actuation strains, and energy barrier of interfacial ion transfer is reduced. As a result, the electro-mechanical transduction efficiency of actuators gets significantly improved. The as-delivered energy density of devices is stronger than that of mammalian skeletal muscle. Based on the high actuation performances, we demonstrate a fiber-shape soft actuator that can be directly injected into biological tissue just using syringe. The injectable actuator is promising for surgical navigation and physiological monitoring.
