Dear Colleagues,

With the advent of Industry 4.0, IoT, and Smart City concepts, the need for cheaper, smaller, smarter, and, above all, less power-hungry gas sensor devices is a reality that requires and demands a paramount effort from the research and engineering community. Among the requisites, the most constraining and challenging is the need for less power-hungry sensors, meaning, from nearly-zero to microwatt power devices. The miniaturization of devices has been the pre-eminent approach despite it having been proved insufficient in most cases. Therefore, other approaches have been also explored: light-driven sensors, room temperature sensors, passive sensors, colorimetric sensors, NFC tags, etc.

This Special Issue of Sensors will focus on recent developments in low power gas sensor technologies. Original papers describing completed and unpublished work that are not currently under review by any other journal or magazine are solicited. Both reviews and articles are welcome.

Dr. Cristian Fábrega
Guest Editor

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. 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 2600 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.
