Modeling electronic noses [2022-2024]
Electronic nose are a new and modern non-destructive technology. In previous projects we have developed models for the case of electronic noses based on metal oxide resistive sensors and conductive polymer resistive sensors for the project 2016-2018 and for the case of electronic noses based on QCM ( Quartz Crystal Microbalance)acoustic sensors for the project 2019-2021 . The project 2022- 2024 is the continuation of previous projects, we want to develop physicochemical models and thermodynamic models for the case of electronic noses based on SAW (Surface Acoustic Wave) sensors, MOSFET (Metal Oxide Semiconductor Field Effect Transistor) sensors , electrochemical sensors, optical sensors. These models are differential equations that relate the responses of the sensors to the concentrations of the components of the gas mixture for the physicochemical models and the entropy and enthalpy of adsorption to the selectivities of the sensors for the thermodynamic models. The physicochemical models can be used to test experimental data for consistency. The thermodynamical models are an extension of already exist models of the interaction between one sensor and one gas.
