摘要

呼吸作为维持生命的关键生理过程，与呼吸暂停、哮喘等多种呼吸系统疾病密切相关.为了满足日益增长的健康监测需求，本文创新性地提出了一种集成柔性撑鼻器的双通路可穿戴MEMS（Micro-Electro-Mechanical Systems）呼吸监测微系统.该微系统集成了柔性撑鼻器、呼吸传感器和信号处理模块，能够持续实时监测鼻腔内气流.传感器的敏感单元采用折叠式金属电阻结构，通过平面MEMS技术沉积在玻璃基底上，基于热阻效应，实现信号测量.传感器嵌入柔性撑鼻器后，可同时监测鼻腔内左右两侧的呼吸信号，尤其适合长时间连续监测.通过信号模拟及性能测试，结果表明该传感器在灵敏度、响应速度和抗干扰能力上表现出色，并且在模拟呼吸暂停和哮喘等疾病的测试中，传感器能够准确区分正常与异常的呼吸信号，可用于进一步分析各种呼吸疾病.基于此，本文开发了一种集成柔性撑鼻器的双通路可穿戴MEMS呼吸监测装置，旨在实现连续、实时且长时间的呼吸监测，特别适用于睡眠期间的异常呼吸筛查与健康监控.此外，该系统还能捕捉人体鼻周期的变化信息，为深入分析呼吸模式和生理节律提供了新的数据维度，展现了在长期健康管理中的潜在应用价值.

Abstract

Breathing

as a crucial physiological process for sustaining life

is closely related to various respiratory diseases such as sleep apnea and asthma. To meet the increasing demand for health monitoring

this paper innovatively proposes a dual-channel wearable MEMS (Micro-Electro-Mechanical Systems) respiratory monitoring microsystem integrated with a flexible nasal expander. This microsystem incorporates a flexible nasal expander

a respiratory sensor

and a signal processing module

enabling continuous real-time monitoring of airflow within the nasal cavity. The sensor’s sensitive element adopts a folded metal resistor structure

deposited on a glass substrate through planar MEMS technology

utilizing the thermoresistive effect to achieve signal measurement. When embedded in the flexible nasal expander

the sensor can simultaneously monitor breathing signals from both sides of the nasal cavity

making it especially suitable for long-term continuous monitoring. Signal simulation and performance testing results demonstrate that the sensor exhibits excellent sensitivity

response speed

and anti-interference capability. In tests simulating respiratory conditions such as sleep apnea and asthma

the sensor accurately differentiates between normal and abnormal breathing patterns

supporting further analysis of various respiratory diseases. Based on this

the paper develops a dual-channel wearable MEMS respiratory monitoring device integrated with a flexible nasal expander

aimed at continuous

real-time

and long-term respiratory monitoring

particularly suitable for abnormal breathing screening and health monitoring during sleep. Additionally

this system captures changes in the nasal cycle

providing new data dimensions for in-depth analysis of breathing patterns and physiological rhythms

highlighting its potential application value in long-term health management.
