Novel Trends in Gas Sensing

Dear Colleagues,

In the last six decades, several approaches and relative analytical methods for gas sensing have already been explored in diverse application fields including environmental toxic gases control, the domestic control of hazardous atmosphere, and clinical medicine in the detection of cancer symptoms.

Most of these approaches and respective methods are mainly based on the selected physical and chemical effects. However, taking into account the most important analytical and usable parameters, such as sensitivity, selectivity, reversibility, dynamic characteristics, power consumption, and fabrication costs, only six main groups of gas-sensing devices and systems have found common application, including those exploiting catalytic, conductometric, electrochemical, optical, optoelectronic, and piezoelectric effects.

This Special Issue is intended to be a comprehensive Issue on novel trends in the development of various types of gas-sensing approaches and related devices including the recent technological improvements for emerging applications, including the outstanding concept of electronic noses.

Topics include but are not limited to devices and systems including conductometric gas sensors using metal oxides and other innovative materials, catalytic and electrochemical gas sensors, optical fiber gas sensors, and surface acoustic wave gas sensors. Furthermore, other areas such as advanced signal processing techniques and data analysis including pattern recognition methodologies can also be discussed.

Both original research papers as well as review articles are welcome. I hope that this SI will provide an overview of the present status and future outlook of the aforementioned topics.
