Microinterventional in-sensor computing system for real-time metabolic health assessment.
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
Microneedle biosensors enable dynamic monitoring of interstitial fluid biomarkers, but remain constrained by sensing interface susceptibility to motion artifacts and the prohibitive energy consumption of wireless cloud-based processing. Here, we report a bio-inspired, self-anchoring microinterventional in-sensor computing system. By leveraging a starfish-inspired suction cup-microneedle self-anchoring mechanism, the system effectively counteracts microneedle extrusion, attenuating signal fluctuations by 38-fold and enhancing signal intensity by up to 5.49-fold compared to conventional planar devices. Crucially, the high-fidelity data acquisition reduces the computational burden, enabling the deployment of a lightweight algorithm (43 KB) on a coin-sized embedded circuit, achieving 98.68% diagnostic accuracy and a 120-h battery life via local closed-loop feedback. Validation in a porcine model confirmed the system's capability to capture continuous biochemical dynamics. This co-design of a robust biomimetic interface and lightweight deep learning paves the way for next-generation wearables capable of performing high-fidelity, on-chip metabolic risk stratification in dynamic daily settings.
