SESSION SYNOPSIS
Gas sensors play a crucial role in several areas, including environmental monitoring, healthcare, and industrial safety, providing valuable information on air quality and the presence of hazardous gases. As the demand for more sensitive, selective, and rapidly responsive sensors grows, so does the need for new sensors with improved performance and reliability.
This special session aims to highlight the latest advances and research in gas sensing technologies, ranging from novel sensing materials to sensor characterization and modeling. In particular, recent advances in nanostructured materials can be explored, including their synthesis, structural characterization, and integration into sensor design. Electrochemical and metal-oxide-semiconductor (MOX) gas sensors are among the most commonly available in the market, but still present open challenges and potential for improvement. In addition to these technologies, innovative transduction mechanisms are emerging which operate across a wide frequency range from DC to microwave frequencies. For these emerging technologies, which offer several advantages in terms of cost, response time and power consumption, research is needed to make such novel devices more competitive with conventional ones.
As sensor technologies become more sophisticated, the ability to accurately model sensor behavior becomes increasingly important. This includes not only the physical and chemical aspects of sensing, but also the integration of computational methods to enhance sensor functionality. In this context, soft sensors represent an exciting frontier in gas sensor technology.
Finally, the evaluation of the metrological performance of sensors is also a topic of paramount importance. There is an increasing emphasis in this regard, as accurate calibration and evaluation of the metrological performance of sensing devices is essential to ensure reliable measurements in their intended applications.
