Special Issue Information

Dear Colleagues,

Low-power gas sensors represent a key component of the Internet of Things (IoT) era, effectively collecting information on specific gaseous species and transforming it into an electrical signal. In particular, gas sensors that detect minute concentration of hazardous gases have immediate technological application in food processing, medical diagnosis, fuel control for automobiles, aerospace vehicles, and environmental monitoring. Traditionally, various gas sensor types, including electrochemical, semiconductor, optical, capacitance-based, calorimetric, and acoustic-based gas sensors, have been validated and commercialized. With the advent of the IoT era, however, the requirements for successful gas sensors have diversified, involving novel key performance criteria such as miniaturized size, low power consumption, and easy integration with electronic circuits. In addition, individual sensor devices as well as gas sensor systems including heaters, circuit elements such as low-power wireless transmitters, and IoT platform integration have received significant research attention. This Special Issue of Sensors aims to collect both reviews and original research papers on advancing gas sensor technology for the IoT era. Potential topics include but are not limited to the following:

  • Design of nanomaterials for gas sensors
  • Self-activated sensing materials
  • Self-heated sensing materials
  • Heaterless sensing materials
  • Synthesis methods for sensing materials
  • Sensing materials characterization
  • Design of catalysts for high selectivity
  • First-principle calculation
  • Sensing measurement system
  • Sensor arrays technologies
  • Circuit and Electrodes design for sensor arrays
  • NEMS and MEMS for gas sensors
  • Artificial intelligence methods for gas sensors
  • Signal processing for gas sensors
  • Olfactory system

Manuscript Submission Information

Manuscripts should be submitted online at 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 papers will be 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. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
