口罩是减少接触病毒和其他环境危害（如空气污染）的关键个人防护设备。将灵活和可穿戴的传感器集成到口罩中可以为个人和公共健康提供有价值的见解。呼吸监测面罩所需的优点，包括多功能感测能力和连续、长期的动态呼吸过程监测，迄今为止尚未开发。在这里，我们设计了一个有效的人体呼吸监测面罩的基础上灵活的La 0.7Sr 0.3MnO 3（LSMO）/云母呼吸传感器。在临床监测模式和日常监测模式两种应用场景下研究了传感器的能力和系统测量，以监测、识别和分析不同的人体呼吸状态，即，咳嗽正常呼吸深呼吸该传感系统在连续和长时间监测人体呼吸方面表现出超稳定性和多模态能力。我们确定，在监测人体呼吸，热扩散的LSMO是负责柔性LSMO/云母传感器的电阻变化。仿真和实验结果表明，柔性LSMO/云母传感器在不同的呼吸状态下具有良好的兼容性。我们的工作为新型柔性和可穿戴电子设备的设计开辟了一条路线。
Face masks are key personal protective equipment for reducing exposure to viruses and other environmental hazards such as air pollution. Integrating flexible and wearable sensors into face masks can provide valuable insights into personal and public health. The advantages that a breath-monitoring face mask requires, including multi-functional sensing ability and continuous, long-term dynamic breathing process monitoring, have been underdeveloped to date. Here, we design an effective human breath monitoring face mask based on a flexible La0.7Sr0.3MnO3(LSMO)/Mica respiration sensor. The sensor’s capabilities and systematic measurements are investigated under two application scenes, namely clinical monitoring mode and daily monitoring mode, to monitor, recognise, and analyse different human breath status,i.e., cough, normal breath, and deep breath. This sensing system exhibits super-stability and multi-modal capabilities in continuous and long-time monitoring of the human breath. We determine that during monitoring human breath, thermal diffusion in LSMO is responsible for the change of resistance in flexible LSMO/Mica sensor. Both simulated and experimental results demonstrate good discernibility of the flexible LSMO/Mica sensor operating at different breath status. Our work opens a route for the design of novel flexible and wearable electronic devices.
