Screen-Printable p- and n‑Type Functionalized Graphene Inks for Flexible Textile Thermoelectric Generators.
Article in ACS omega, 2025. 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
Wearable thermoelectric (TE) generators offer a sustainable solution for powering low-energy electronics by harvesting body heat. In this study, we report the development of fully screen-printable, solution-processed graphene inks exhibiting p- and n-type thermoelectric behavior for flexible textile applications. The inks were printed onto woven cotton substrates by using scalable screen-printing methods, forming all-graphene thermoelectric modules that retain textile flexibility and breathability. Electrical characterization demonstrated Seebeck coefficients of +34 μV/K. Under a modest temperature gradient of 40 °C, the TE textile device generated open-circuit voltages up to 5.24 mV with stable operation. The materials and device exhibited good adhesion, flexibility, and thermal response without requiring postprocessing or high-temperature annealing. This work presents a cost-effective, scalable, and environmentally benign approach to fabricating wearable thermoelectric systems, offering strong potential for powering flexible electronics, health monitoring sensors, and future energy-autonomous garments.
