A flexible sensor that can be attached to the body to collect vital data wirelessly enables real-time human healthcare management. One potential application for home-use healthcare devices is monitoring of sleep conditions to diagnose sleep apnea syndrome. Such data are not readily gathered using conventional tools, owing to the bulk and cost of instrumentation. In order to monitor respiration at home, it is necessary to improve sensing performance and long-term stability of the sensors without sacrificing wearability and comfortability. To build a platform for wireless home-use respiration monitoring, this study develops a mask-borne flexible humidity sensor using ZnInS nanosheets as a humidity-sensitive material with high sensitivity and stability for more than 150 h. As proof-of-concept, long-term wireless respiration monitoring is demonstrated during sleep to identify symptoms of sleep apnea in wearers.
一种可附着于身体以无线收集生命数据的柔性传感器能够实现实时人体健康管理。家用医疗设备的一个潜在应用是监测睡眠状况以诊断睡眠呼吸暂停综合征。由于仪器的体积和成本，使用传统工具不容易收集此类数据。为了在家中监测呼吸，有必要在不牺牲可穿戴性和舒适性的前提下提高传感器的传感性能和长期稳定性。为构建一个用于无线家用呼吸监测的平台，本研究开发了一种面罩式柔性湿度传感器，该传感器使用ZnInS纳米片作为湿度敏感材料，具有高灵敏度且能在超过150小时内保持稳定。作为概念验证，展示了在睡眠期间进行的长期无线呼吸监测，以识别佩戴者的睡眠呼吸暂停症状。
