Abstract Real‐time monitoring of respiration plays a very important role in human health assessment, especially and analyzing during exercise sleep. However, traditional humidity sensors still have problems flexibility, sensitivity, durability, so there is an urgent need to develop with high stretchability, environmental resistance as respiratory applications. Here, based on the double network hydrogel structure polyvinyl alcohol polyacrylamide, highly sensitive, stretchable, environmentally stable organic sensor has been manufactured by using synergistic effect lithium chloride MXene. The shows rapid response range 40–85% RH, sensitivity −103.4%/% RH. In addition, it exhibits more than 3000% mechanical strain excellent resistance, which attributed chemical cross‐linking multiple hydroxyl groups glycerol forming rich hydrogen bonds water polymer chains. used for real‐time breathing sleep processes. This work provides new strategy preparing high‐performance, extensibility, stability hydrogel‐based monitoring.

Human metabolite moisture detection is important in health monitoring and non-invasive diagnosis. However, ultra-sensitive quantitative extraction of respiration information real-time remains a great challenge. Herein, chemiresistors based on imine-linked covalent organic framework (COF) films with dual-active sites are fabricated to address this issue, which demonstrates an amplified humidity-sensing signal performance. By regulation monomers functional groups, these COF can be pre-engineered achieve high response, wide range, fast recovery time. Under the condition relative humidity ranging from 13 98%, COFTAPB-DHTA film-based sensor exhibits outstanding sensing performance expanded response value 390 times. Furthermore, values highly linear range below 60%, reflecting mechanism at molecular level. Based dual-site adsorption (-C=N-) (C-N) stretching vibrations, reversible tautomerism induced by hydrogen bonding water molecules demonstrated main intrinsic for effective detection. In addition, synthesized further exploited effectively detect human nasal oral breathing as well fabric permeability, will inspire novel designs humidity-detection devices.
