May 01, 2018· 1. Introduction. The fabrication of lowcost, portable, accurate and realtime sensors for organic vapour detection is of considerable interest in biomedical fields and in food quality monitoring [].Ethanol and acetone represent the most common examples of volatile organic compounds (VOCs).
Film bulk acoustic resonators (FBARs) are widely applied in mass biosensing and pressure sensors, owing to their extreme sensitivity and integration ability, and ability to miniaturize circuits. A volatile organic compound (VOC) sensor with a polymercoated diaphragm, using FBARs as a strain sensing element is proposed and optimized. This vapor sensor is based on organic vapor …
May 15, 2018· However, when the resonant cantilever sensor is introduced to the environment that contains both the VOC molecules and the evaporated solvent vapor like water, the true response signal of the lowconcentration VOC will be drowned in the strong interference signal of the highconcentration solvent vapor …
Sep 08, 2020· Abstract: Volatile organic compound (VOC) is one of the most widely spread and hazardous environmental pollutants. In this work, a VOC vapor optical fiber sensor is proposed and …
