Abstract

The “vital capacity” is a crucial biomechanical marker for evaluating lung health, and is crucial for diagnosing conditions that include asthma and chronic obstructive pulmonary disease (COPD). However, existing monitoring devices are often limited by their dependence on an external power source, and are susceptible to environmental impact to reduce the accuracy of detection. This study therefore presents a novel magnetoelectric triggered sensor (MTS) for self-powered vital capacity monitoring, where the sensor can directly convert the respiratory airflow into electrical signals and monitor vital capacity. The MTS maintains high signal stability, even when operating in high-humidity environments, to enable precise monitoring of the Forced Vital Capacity (FVC) and Peak Expiratory Flow (PEF), thereby serving as an effective instrument for evaluating vital capacity function. This work not only highlights the significant potential of this new approach to self-powered spirometry sensing but also paves the way for the development of portable and wearable devices for the monitoring of respiratory disease.

磁电触发自供电生命容量传感器
“肺活量”是评估肺部健康的重要生物力学指标,对于诊断哮喘和慢性阻塞性肺疾病(COPD)等疾病至关重要。然而,现有的监测设备往往受到外部电源的限制,并且容易受到环境影响,从而降低了检测的准确性。因此,本研究提出了一种用于自供电肺活量监测的新型磁电触发传感器(MTS),该传感器可以直接将呼吸气流转换为电信号并监测肺活量。MTS保持高信号稳定性,即使在高湿度环境下操作,也能精确监测强制肺活量(FVC)和呼气峰值流量(PEF),从而作为评估肺活量功能的有效工具。这项工作不仅突出了这种自供电肺活量测量传感新方法的巨大潜力,而且为开发用于监测呼吸系统疾病的便携式和可穿戴设备铺平了道路。
