| 摘要 |
The invention relates to a method and sensor structure for measuring the concentration of nonpolar gases such as carbon dioxide. According to the method, the concentration of the nonpolar gas adsorbed/absorbed in a polymer film (2) is determined by detecting the weight of the polymer film (2). According to the invention, the dielectric coefficient of the polymer film (2) is measured, and on the basis of this, a correction is made in the concentration measurement result obtained from the weight measurement.
