“…VOCs in DEB are either formed by cellular metabolic processes or absorbed/inhaled from environmental sources 29 . For example, chronic obstructive pulmonary (COP) 30 , Lung cancer cells 28 , congestive heart failure (CHF) 30 , etc., may produce these VOCs. Due to the low solubility of VOCs in blood, they spread quickly into the exhaled breath 31 .…”

“…Detecting carbon dioxide ( CO 2 ) concentration in DEB can give non-invasive information about an individual's respiratory and metabolic functioning 31 . Bhagya et al 30 proposed a capnographic sensor to sense CO 2 concentration in DEB based on an acoustic virial equation to diagnose COP and CHF diseases. Oort et al 32 investigated the vital role of analyzing DEB pneumonia detection.…”

The volatile particles and molecules in our dry exhaled breath can reveal enormous information about the health of any person, such as the person’s respiratory and metabolic functioning. Beyond the carbon dioxide level is an indicator of life, it provides important health-related data like people’s metabolic rate. This study considers periodic open and closed resonators for measuring carbon dioxide concentration in dry exhaled breath. Transfer matrix and green methods are used to simulate the interaction between acoustic waves and the proposed sensor. The band gaps using the green method coincide with the transmittance spectra by the transfer matrix. The suggested sensor recorded a sensitivity of $$5.3 Hz.{m}^{-1}.s$$ 5.3 H z . m - 1 . s , a figure of merit of 10,254 $${m}^{-1}.s$$ m - 1 . s , a detection limit of $$5\times {10}^{-6} m.{s}^{-1}$$ 5 × 10 - 6 m . s - 1 , and a quality factor of $$3\times {10}^{6}$$ 3 × 10 6 . Furthermore, the efficiency shows that the proposed design is appropriate as a diagnostic sensor for different diseases such as chronic obstructive pulmonary. Besides, cylindrical-adapted sensors are urgently needed in medicine, industry, and biology because they can simultaneously be used for fluid transport and detection.
