Advanced functional materials for next generation gas sensing applications

Abstract

Gas sensors have become integral to modern technology, finding applications across various fields such as environmental monitoring, industrial safety, medical diagnostics, and even household appliances. These sensors play a vital role in detecting harmful gases, ensuring human safety, and enhancing the quality of life by monitoring air quality and pollution levels. The growing concerns around climate change, urbanization, and industrial emissions have further driven the demand for reliable and efficient gas sensing technologies [1]. The fundamental principle behind gas sensors is their ability to detect specific gases in the environment and convert that detection into measurable electrical signals. Over the years, the technological advancements in gas sensors have resulted in smaller, more sensitive, and energy-efficient devices capable of detecting gases at very low concentrations (ppm or ppb levels) [2].
