• Humidity sensing-based wearable respiration monitoring systems have promising application prospects in providing the critical health information. Currently, due to the inherent flexibility and compatibility, fabric-based wearables have attracted tremendous interest in humidity sensing. Herein, we proposed a humidity sensor made from fabric coated with MXene and multi-walled carbon nanotubes (MWCNT). The sensor showed 265% response at 90% relative humidity (RH) and great response stability under deformation. The humidity response of MXene/MWCNT fabric (MC-fabric) sensor only varied 7% under stretch, which is greatly alleviated compared with pristine MXene fabric sensor (35% under stretch). The MC-fabric sensor, integrated into a mask, can accurately identify diverse human respiration patterns despite the deformation caused by motions. This work not only offers a facile modification strategy to enhance the sensing robustness under deformation, but also provides a feasible method for real-time breath analysis. •MXene and MWCNT was assembled on fabric for humidity detection.•The humidity response stability under deformation was improved by introduced MWCNT.•A smart mask was designed to implement wireless real-time respiration monitoring.•The electronic fabric can accurately track respiration under motion states.
