Special Issue Information
Dear Colleagues,
Gas sensors are the core components of olfactory sensing and are generally classified as chemical sensors. They can sense the components and concentrations of the atmosphere in the environment and have broad application prospects in environmental monitoring, industrial production, medical testing, food safety, military aerospace, and other fields. The sensitivity, selectivity, stability, response and recovery speed, power consumption, and cost of gas sensors have always been used to evaluate their performance level and application potential. It can be seen that the evaluation of gas sensors is comprehensive, which also determines the diversity and complexity of related research work. Semiconductor gas sensors have been favored by researchers due to their inherent advantages, with the widest research scope, the best research foundation, the deepest research degree, and the greatest research prospects.
Researchers are more focused on their own strengths, and their research on gas sensors is also multifaceted. Although these studies have played a role in promoting the development of the gas sensor field, it is still necessary to summarize and integrate research on specific topics with appropriate standards, and contribute concentrated wisdom and solutions. This Special Issue of “Chemosensors” mainly focuses on the latest developments in the field of gas sensors, especially the improvement of their various performance indicators, whether single or multiple. This Special Issue welcomes research on gas sensors using traditional methods, such as innovative work in sensitive materials, excitation sources, electrodes, circuits, signal processing, etc. At the same time, this Special Issue strongly encourages submission of papers studying gas sensors from a new perspective, such as using cutting-edge academic ideas or research methods from other fields for cross research, even if the conclusions are not novel or prominent. This Special Issue not only supports experimental exploration, but also strongly supports theoretical calculations or simulation analysis, especially looking forward to comprehensive analysis results on gas sensing mechanisms. This Special Issue aims to build a platform for researchers in the field of gas sensors to share their achievements, gather the latest research progress, and jointly promote the vigorous development of the gas sensor field.
In this Special Issue, all short communications, original research articles, and timely reviews are cordially solicited. Topics of interest include, but are not limited to, the following areas:
(1) Emerging materials for gas sensors; (2) Emerging applications for gas sensors; (3) New sensitization strategies for gas sensors; (4) Moisture resistance study for gas sensors; (5) Theoretical calculation for gas-sensitive mechanisms; (6) MEMS gas sensors; (7) Wearable gas sensors; (8) Gas sensor arrays. (9) Applications of artificial intelligence (machine learning) to gas sensors; (10) Controllable synthesis of sensing materials; (11) Microwave type gas sensors; (12) Solid state electrolyte gas sensors.
We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Chemosensors is an international peer-reviewed open access monthly journal published by MDPI.
