Face mask integrated with flexible and wearable manganite oxide respiration sensor

Face masks are key personal protective equipment for reducing exposure to viruses and other environmental hazards such as air pollution. Integrating flexible wearable sensors into face can provide valuable insights public health. The advantages that a breath-monitoring mask requires, including multi-functional sensing ability continuous, long-term dynamic breathing process monitoring, have been underdeveloped date. Here, we design an effective human breath monitoring based on La0.7Sr0.3MnO3 (LSMO)/Mica respiration sensor. sensor’s capabilities systematic measurements investigated under two application scenes, namely clinical mode daily mode, monitor, recognise, analyse different status, i.e., cough, normal breath, deep breath. This system exhibits super-stability multi-modal in continuous long-time of the We determine during thermal diffusion LSMO is responsible change resistance LSMO/Mica Both simulated experimental results demonstrate good discernibility sensor operating at status. Our work opens route novel electronic devices.
