Special Issue Information

Dear Colleagues,

Sensors are the bridge connecting the physical world and the digital world. Gas sensors belong to the sensor industry, which is a converter that converts the volume fraction of a certain gas into corresponding electrical signals. It can convert information such as gas composition and concentration into information that can be utilized by personnel, instruments, computers, etc. There are numerous application fields for gas sensing, mainly including smart homes, automotive electronics, consumer electronics, wearable devices, smart healthcare, industrial processes, environmental monitoring, etc., covering a wide range of industries, with a variety of types and high dispersion. In addition, the complexity and personalization of its terminal products are high. Given the widespread and growing market demand for gas sensors, research on high-performance gas sensors has become increasingly necessary and has received sustained attention and investment from multidisciplinary researchers.

In scientific research, improving the performance indicators of gas sensors is the ultimate goal of researchers. Furthermore, the improvement of sensor performance can be achieved through various means or ideas and therefore involves multiple disciplines such as materials science, chemistry, physics, microelectronics, electronic circuits, signals and systems, and so on. In the most recent research, artificial intelligence has become one of the efficient methods for screening target sensing materials.

This Special Issue of Electronics will collect the latest research achievements in the field of gas sensors, providing a platform for researchers from different disciplines to exchange and share their achievements. This Special Issue welcomes ground-breaking and innovative research work in the field of gas sensors, acknowledges systematic and comprehensive experimental results, and encourages attempts in modeling, simulation, and theoretical calculations. This Special Issue focuses on a wide range of research directions, aiming to establish a comprehensive collection of papers related to the research progress of gas sensors, and is not limited to the materials, technologies, and applications mentioned in the title. This Special Issue is expected to make phased contributions to the development of gas sensors, provide original thinking, and even play a demonstration role in the academic and industrial development of this field to a certain extent.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

(1) Room-temperature gas sensors;

(2) Promotion strategies for gas-sensing performance;

The selective detection of propane gas molecules using semiconductor gas sensors has always been a challenge within research. In this study, we successfully synthesized a γ-Fe2O3 nanomaterial with a selective catalytic effect on propane and loaded it onto a ZnO sensing material to construct a double-layer microsensor, which showed good sensing response characteristics in the detection of the refrigerant R290 (which is mainly propane). In addition, we also prepared a series of iron oxides, including nanomaterials such as α-Fe2O3, Fe3O4, and FeO, as well as γ-Fe2O3 materials with different specific surface areas obtained at various processing temperatures, and we carried out gas sensing research on R290. The results show that the γ-Fe2O3 material has a better sensitivity to R290, and the γ-Fe2O3 material calcined at 200 °C shows the best performance. Our results can provide a theoretical basis for the design and optimization of semiconductor gas sensors for alkane detection. Full article

In the modern world, gas sensors play a crucial role in sectors such as high-tech industries, medicine, and environmental monitoring. Among these fields, oxygen sensors are the most important. There are several types of oxygen sensors, including optical, magnetic, Schottky diode, and resistive (or chemoresistive) ones. Currently, most oxygen-resistive sensors (ORSs) described in the literature are fabricated as thick layers, typically deposited via screen printing, and they operate at high temperatures, often exceeding 700 °C. This work presents a novel approach utilizing atomic layer deposition (ALD) to create very thin layers. Combined with appropriate doping, this method aims to reduce the energy consumption of the sensors by lowering both the mass requiring heating and the operating temperature. The device fabricated using the proposed process demonstrates a response of 88.21 at a relatively low temperature of 450 °C, highlighting its potential in ORS applications based on doped ALD thin films.
