AI Technical Summary
Existing portable respiratory monitoring technologies struggle to quantitatively reconstruct expiratory flow rate and lung volume in open environments. Traditional pulmonary function instruments are bulky and unsuitable for home-based and continuous monitoring, while thermoelectric respiratory devices are difficult to quantify when airflow boundary conditions are uncertain.
By employing a co-design of a confined flow channel structure and thermoelectric sensing components, a stable boundary layer is formed by constructing a confined flow channel inside the mask. Combined with a thermoelectric-airflow inversion model, quantitative reconstruction of exhaled airflow velocity, flow rate, and cumulative volume is achieved, and closed-loop feedback is provided by combining a virtual reality training module.
It enables quantitative monitoring of expiratory flow rate and lung volume in an open environment, reduces power consumption, supports long-term wear, provides real-time risk alerts and virtual reality training, and forms an integrated solution of monitoring, assessment and rehabilitation.
