· Introduction to Gas Sensor. A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type …

· The article presents a new method of monitoring and assessing the course of the dry methane reforming process with the use of a gas sensor array. Nine commercially available TGS chemical gas sensors were used to construct the array (seven metal oxide sensors and two electrochemical ones). Principal Component Regression (PCR) was used as a calibration method.

Future Trends in the Development of Gas Sensors. Wolfgang Göpel. Pages 365409 . About this book. Introduction. There were two reasons that induced me to plan and to organize this book, the first was the lack of a text entirely devoted to the subject of gas sensors, notwithstanding some books devoted to the various kind of chemical sensors have recently been published. The …

· Stability is one of the key parameters in the development of gas sensors for the real market as the sensors should produce a stable as well as reproducible signal at least for 2–3 years which corresponds to 17,000 h–26,000 h of operation . Low stability is an issue with SMO materials. Sensor stability can be of two types. One is related to the reproducibility of the …

MPSPR for gas sensor development. Unlike traditional SPR, MPSPR can work also with gas and vapor samples. It can be used to finetune sensitive coatings for specific gas components. Amongst others, MPSPR is able to detect hydrogen (2 Dalton) on Palladium surface. Also surface interaction with different humidity can be studied at the nanoscale (more on gas …

· The past decades have witnessed considerable development in smart gas sensors and electronic noses (enoses) using machine learning [59,60,61]. Machine learning mainly contributes to two major factors of a sensing device: drift compensation and selectivity. Over the past few decades, several methods have been investigated to address the drift error through …

· Sensitivity of different type of sensors has been studied to H2S and NO gases. The results show that the response of ZnO sensors to H2S arises from grain boundary only whereas both grain boundaries and intragrain resistances contribute towards response to NO. In addition, oxygen vacancies in the lattice were also seen to help in improvement of sensor response. …
