1 · What the graph read from it

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.

2 · The registry

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

Access to reliable, clean energy remains a major challenge for the unhoused and off-grid communities. Here, we introduce a self-powered magnetoelastic tent that leverages the giant magnetoelastic effect to harvest energy from human motion and environmental stimuli. The smart tent integrates magnetoelastic textiles, consisting of a magnetomechanical coupling layer and a magnetic induction layer, converting mechanical motion into electricity. Optimizing weaving patterns, layer stacking, and conductive fiber turns enables robust energy generation, with a representative magnetoelastic textile unit delivering a maximum instantaneous power of 0.094 mW, stable operation over 12,000 continuous cycles, and intrinsic waterproof performance. Simple hand tapping can charge a 0.22-μF capacitor to 5.80 V within 1.5 s, providing sufficient power for small electronics. Lightweight, recyclable, and weather resistant, the tents maintain stable performance under representative outdoor conditions. This work presents a scalable platform for sustainable, decentralized energy harvesting to expand supplementary energy access in temporary shelter settings.
