All-in-One Wearable Hydrogel Patch for Multimodal Visualized and Quantitative Heatstroke Monitoring
Clinical Snapshot
PICO Framework
| P — Population | Outdoor workers, athletes, and individuals with impaired thermoregulation at risk of heat-related illness |
| I — Intervention | All-in-one wearable hydrogel patch with thermogalvanic sensing and electrochemical ion detection |
| C — Comparator | Existing invasive monitoring strategies and external power-dependent devices |
| O — Outcomes | Real-time temperature tracking, sweat Na+ and K+ ion detection, thermochromic visualization, and heatstroke risk assessment |
Bottom Line
This proof-of-concept study presents an innovative wearable patch combining temperature sensing with sweat electrolyte monitoring for heatstroke prevention. The self-powered, multimodal approach addresses key limitations of current monitoring methods by providing real-time, non-invasive assessment with visual feedback. However, the clinical utility remains unproven without validation studies demonstrating accuracy against gold-standard measurements, sensitivity for detecting early heatstroke, and safety in target populations. While the technology shows promise for high-risk occupational settings and athletic monitoring, clinicians should await peer-reviewed validation data before considering clinical applications. The device's potential value lies in proactive monitoring rather than diagnostic confirmation of established heatstroke.

Abstract
Heat-related illnesses, particularly heatstroke, pose serious risks to outdoor workers, athletes, and individuals with impaired thermoregulation. Existing monitoring strategies are limited by invasive measurements, reliance on external power sources, and lack of real-time multimodal feedback. Here, this study presents an all-in-one wearable patch that integrates a dual-functional self-powered thermogalvanic hydrogel with a selective electrochemical interface for intuitive visual feedback, dynamic temperature tracking, and durable sweat analysis. The hydrogel enables real-time thermochromic visualization and active thermoelectric sensing of body temperature, while an integrated electrochemical module allows continuous and selective detection of Na+ and K+ ions in sweat. The multiplexed physical-chemical health-monitoring patch provides a multimodal dual-stage evaluation of body temperature and sweat ion level toward improving metabolic status control and alerting individual to heatstroke risk, holding promise for developing personalized healthcare and a scalable route to proactive heatstroke prevention.
