Strain-localized luminescent e-skin for high-resolution pressure mapping and visual force feedback.
Article in Nature communications, 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
Electronic skins (e-skins) that emulate human intuitive tactile perception with visual feedback capabilities are vital for next-generation wearables, robotics, and biomedical applications. However, existing visualized pressure mapping systems either require dense pixelated arrays that add bulk, complexity and signal crosstalk, or rely on rigid or semi‑rigid architecture, and are not able to conform to dynamically changing curved, soft surfaces. Here, we report a soft mechano-electroluminescent e-skin for high-resolution visualized pressure mapping. Quantitative pressure sensing is achieved on curved and compliant substrates. Built with an ultrathin, entirely soft microstructured architecture, it harnesses strain-localized deformation and intrinsic, in‑situ force-electric-optical coupling within a continuous device stack to achieve high‑fidelity pressure mapping without discrete sensing pixels. It achieves a spatial resolution of 30 μm (847 dpi) and high luminescent sensitivity (1.12 cd·m⁻²·kPa⁻¹). This e-skin allows real-time mapping of pressure distributions and recognition of fine tactile features like fingerprints. Integrated with plantar sensors and also laparoscopic tools, it also enables visual force feedback, enhancing gait analysis and surgical training, respectively. This approach offers a soft, compact, multimodal platform for intelligent tactile interfaces.
