摘要

Abstract

Improvements to body-surface physiological monitoring ability including real-time

accuracy and integration

are essential to meet the

expansive demands for personal healthcare. As part of this

simultaneous monitoring of sweat metabolites and body temperature offers an exciting path to maximizing diagnostic precision and minimizing morbidity rates. Herein

we report a high-performance biomarker-temperature sensor made of a single As

chalcogenide glass fiber to monitor physiology evolution on body-surface. The sensor integrates efficient thermal resistance and fiber evanescent wave effects

permitting the independent sensing of temperature and biomarkers with an ultrahigh temperature coefficient of resistance (−5.84% K

–1

)

rapid temperature response (0.3 s) and excellent IR sensing sensitivity. Moreover

by attaching a fiber to the wrist

we demonstrate simultaneous observation of both sweat metabolite (urea and lactate) and temperature changes during exercise. This illuminating sensing method will provide crucial capabilities in physiological monitoring and pave the way for advanced personalized diagnostic.
