圧電セラミックにおける呼息・吸息に伴うマスク内温度変化計測モデルの構築及び肺機能評価システムの提案

抄録

Chronic obstructive pulmonary disease (COPD) has been attracting attention as a respiratory disease that should be prevented because both the number of patients with COPD and the number of deaths associated with COPD are increasing, and a method that can help diagnosis in the home environment is desired. Therefore, this study introduces a mask-type device that piezoelectric ceramics installed in the mask and constructs a model considering the physical relationship between human respiration and the voltage measured through the piezoelectric ceramics. Furthermore, by applying signal processing based on this model, we will attempt to realize a pulmonary function evaluation system that estimates FEV_1.0%, which is used as an index for detecting obstructive disorders.
