Short Biography

Gas sensors serve a pivotal role across diverse applications, spanning household to industrial domains. More recently, their evolution into electronic noses (E-noses) has expanded their utility, even enabling the identification of individuals infected with the coronavirus. The behavior of these sensors profoundly impacts system modeling. Thus, the quest for mathematical models capable of encapsulating sensor responses comprehensively across various environments and scenarios becomes imperative. Within this realm, one of the primary challenges lies in formulating mathematical models, an endeavor that has grown increasingly intricate with time. Regrettably, many proposed equations have fallen short in translating into practical performance, contributing to mounting confusion among researchers.

Highlights of the Talk

In this talk, the aim is to introduce concise modeling equations tailored for metal oxides, drawing from practical observations and meticulous data extraction. The proposed mathematical equation seeks to streamline model parameters in response to fluctuations in temperature, humidity, and gas density variations. This approach aims to enhance the precision of simulating sensor behavior, consequently yielding a more refined and prompt response.
