Published: May 24, 2023

Abstract Breathing is an inherent human activity; however, the composition of air we inhale and gas exhale remains unknown to us. To address this, wearable vapor sensors can help people monitor in real time avoid underlying risks, for early detection treatment diseases home healthcare. Hydrogels with three-dimensional polymer networks large amounts water molecules are naturally flexible stretchable. Functionalized hydrogels intrinsically conductive, self-healing, self-adhesive, biocompatible, room-temperature sensitive. Compared traditional rigid sensors, hydrogel-based humidity directly fit skin or clothing, more suitable real-time monitoring personal health safety. In this review, current studies on investigated. The required properties optimization methods introduced. Subsequently, existing reports response mechanisms summarized. Related works their application safety presented. Moreover, potential field sensing elucidated. Finally, research status, challenges, future trends hydrogel gas/humidity discussed.
